Basic Highway Plan Reading

Forward
This Plan Reading Course is to present a step-by-step procedure on how to read, interpret, and relate to a standard
set of roadway plans; to help identify and interpret symbols used in a standard set of plans; and to help develop the
necessary skills to interpret a set of plans in non-technical terms to laypersons (property owners and others). Along
with this manual you will use plan sheets and standards that specifically relate to a project. The plan sheets/
standards included have been reduced to half their original size so they can be handled more easily.
A partnership of Transportation entities, The Georgia Partnership for Transportation Quality (GPTQ), works
together to improve the quality of the nation’s highways and as one of the initiatives, the GPTQ Steering
Committee created a team from public and private sector organizations to jointly focus on the improvement of
highway construction plans. The team determined that quality improvements were attainable by developing a Plan
Presentation Guide to assist designers in the presentation of the work to be accomplished and thereby making
plans more efficient for the user. This guide can be found on the Georgia DOT Web Pages for further information.
Since it is our intent to provide you, the student, with a “well rounded” exposure to highway construction plans,
you may be asked to look at a plan sheet from a particular project. Please be sure that you are looking at the correct
set of plans for the text that you are reading and the questions you may be asked to answer.

Basic Highway Plan Reading
A Note on Safety
As an employee of the Georgia Department of Transportation, it is your responsibility to direct your concern to one
goal, which is to provide the traveling public with the best and safest roadway system that can be constructed.
With this goal constantly in mind, it is the responsibility of each DOT employee to observe, suggest, and act to
achieve a safe system of roadways throughout the State. Regardless of a specific assigned duty, it is the
responsibility of all the employees of the Georgia Department of Transportation to call to his/her supervisor’s
attention any item, whether in design or construction, which appears to be an obvious hazard to the motoring
public.
Safety is our business and will remain the primary factor in designing and constructing highways.

Nuts and Bolts of the Course
This is a self-instructional study course. The subject matter is arranged so that you the student may work at your
own speed. Each part of the course builds on the information that has preceded it and prepares for information to
follow. Most of the parts present new information. Some parts review important concepts that have been
introduced to you earlier in the program and apply these concepts in new ways.
The idea behind this method is for you to read and study the information, actively participate by writing or
checking off answers to questions, then find out immediately if you are correct. This method reinforces what you
have read and enables you to retain what you have learned for a longer period of time. The retention of information
from a self-instructional study course should be far greater than from a lecture or textbook.
To get the most from this course, start at the beginning. Read each section as it comes; preparing you for the next
section. You will find questions within each section. By answering these questions, you will be able to retain what
you have just read longer than by lecture or discussion.
The answers to these questions appear at the end of the text.

GENERAL INFORMATION
REQUIREMENTS AND SPECIFICATIONS
A requirement occurring in one of the parts of a Georgia DOT contract is as binding as though occurring in all. The
Specifications, Supplemental Specifications, Plans, Special Provisions, and all supplementary documents are all
part of the contract.
WHAT PART OF THE CONTRACT APPLIES?
In case of a discrepancy, certain parts of the contract govern over others. The governing order will be as follows:
1. Special Provisions
2. Project Plans including Special Plan Details
3. Supplemental Specifications
4. Standard Plans including Standard Construction Details
5. Standard Specifications
Calculated dimensions will govern over scaled dimensions.
The Contractor shall take no advantage of any apparent error or omissions in the Plans or Specifications. In the
event the Contractor discovers such an error or omission, he shall immediately notify the Engineer. The Engineer
will then make such corrections and interpretations as may be deemed necessary for fulfilling the intent of the
Plans or Specifications.

SCALE
Roadway and structure plans are drawn to scale in order that they might be presented on easy-to-use sheets.
Roadway plans are normally drawn with an engineer’s scale while structure plans use both engineer’s and
architect’s scales.
10
Chapter 1: Beginning to Read Plans
A civil engineer’s scale has divisions of 10, 20, 30, 40, 50 and 60 to
the inch.
An architect’s (or mechanical engineer’s) scale expresses scale as
fraction of an inch to one foot. Sample scales would be 1/4” = one
foot, 3/8” = 1 foot, 1/8” = 1 foot, or similar.
The engineer’s scale is one that expresses “scale” as 1 inch = 10 feet;
1 inch = 20 feet, 1 inch = 30 feet, 1 inch = 40 feet, 1 inch = 50 feet, 1
inch = 60 feet, or some multiple of these numbers. It is usually 1 foot
long and may be triangular or flat.
Figure 1-9. Civil engineer’s scale (above top)
and architect’s scale (above bottom).
The scales are divided into decimal parts of an inch such as 1/10th inch, 1/20th inch, etc.
The triangular, or six-scale scale, has scales with 10, 20, 30, 40, 50, and 60 divisions to the inch. In the next
drawing, each division equals 1-foot - in the 1” = 10’ scale, there are 10 divisions to the inch. Each division can be
treated in multiples of 10 as well, for example, 1” = 100’, 1” = 1000’, etc.

Chapter 2: Index and Review Summary Sheet
INDEX
An index is required for each set of construction plans to help the user in identifying what sheets are in the set of
plans. The index can be included on the cover sheet on smaller projects with few sheets, but normally it will be
included as a separate sheet directly following the cover sheet.
The index sheet includes a description of each plan sheet with each corresponding sheet number. A listing of all the
Georgia DOT standards and construction drawings relating to that particular project, are also shown along with the
corresponding standard number, the most recent revision date of the standard, and the sheet number.
An area is usually available on the sheet for later additions or deletions of sheets and the total number of all sheets
are shown.
REVISION SUMMARY SHEET
At times after the final set of plans have been drawn up, it will be necessary to revise (change) the design for a
portion of the plans. A Revision Summary Sheet is used for the purpose of keeping a record of those revisions. For
this reason, a revision summary sheet is a required element of a set of construction plans.
Figure 2-1. Index Sheet.
Chapter 2: Index and Revision Summary Sheet
Chapter 2: Index and Review Summary Sheet
12
The Revision Summary Sheet consists of three columns (in addition to the normal project information in the title
blocks). The first column is for the date on which the revision was made; the second column is for the plan sheet
number; and the third column contains a description of the revision, described in enough detail to quickly
understand the nature of the revision. The Revision Summary Sheet will typically follow directly behind the Index
Sheet or the Cover Sheet.
Please identify the question as True or False:
2-1 True False An Index is required for each set of Construction Plans.
2-2 True False A Revision Summary Sheet is part of the contract.
2-3 True False A listing of all Standards and Construction Drawings are included in the index.

Chapter 3: Typical Section
13
INTRODUCTION TO TYPICAL SECTIONS
The typical section is a picture, with dimensions, of how the cross-sectional view of the roadway would appear
after the construction is completed. A cross section is how the view of the road would look if cut from side to side.
Figure 3-1 shows an idealized roadway typical section with the various elements identified.
The left side of Figure 3-1 below illustrates how the roadway is to be constructed in a fill area. The right side of
this typical section illustrates how the roadway is to be constructed in a cut area (the road will be below existing
grade). We will talk in more detail about “cut” and “fill” later. However, the right and left sides of the Typical
Section are interchangeable.
Figure 3-1. Typical Roadway Section.
Look at Construction Plan Sheet #7 and find some of the significant features you should know about this Typical
Section:
1. This is a dual-lane roadway with a median.
2. The travel lanes for each side of the roadway are 24 ft. wide.
3. There is a 6’6” paved shoulder on the outside of each roadway and a two foot paved shoulder on the
inside (median) side of each roadway.
4. The profile grade point is at the construction centerline ( C
L
CONST).
5. The location where the typical section is to be used is shown.
6. Paving requirements are also spelled out under the Normal Tangent Section. Refer to Figure 3-2 on

HORIZONTAL DISTANCE
The dimensions given for Typical Sections are
Horizontal dimensions. This means that the distances
are not measured along the slopes of the roadway.
For example, the distance from the profile grade of
the left lane of the Typical Section to the edge of the
pavement is written as 24’. The distance measured
along the 1/4” per foot slope would be slightly longer
than 24’. Figure 3-3 exaggerates that difference. All
the dimensions shown by level lines are Horizontal
Distances. Explanations of Slopes will be discussed
later in this book.
Figure 3-3. Horizontal Distance compared with Slope Distance.
Use Construction Plan Sheet 7, Tangent Section (Section 3), and answer these questions:
3-1 What is the total thickness of the Asphaltic Concrete?
3-2 What is the material used under the Asphaltic Concrete?
3-3 How wide is the outside unpaved shoulder?
3-4 What is the slope required on the outside paved shoulder?
3-5 How many lanes make up the normal section for each side of this roadway?
3-6 How wide is the median ditch?
Chapter 4: Summary & Detailed Estimate Quantities

SUMMARY OF QUANTITIES
The Summary of Quantities Construction Plan Sheets show all the items of construction that are indicated on the
Plan and Profile Sheets. The items are normally lumped together into like categories and then the categories are
placed in boxes on the sheet with their representative quantities. An exception to this is if it’s stated that an item is
included in the cost of another item. Another exception would be on a small bridge replacement project where
quantities are small and pay items are very limited. In this case, the quantities are placed on the Detailed Estimate
only.
Turn to the Summary of Quantities for Sheets 12 through 19. The Summary of Quantity notes the location, size,
etc., where the item is required.
Figure 4-1. Summary of Quantities.
Using Construction Plan Sheets number 18-30, answer these questions:
4-1 How many tons of aggregate surface course is required?
4-2 How many total linear feet of woven wire field fence is needed?
4-3 Between Sta. 153+00 and 159+25, how many feet of guard rail are required?
4-4 How much concrete and steel reinforcing bar are required at structure 23, Sta. 233+20?
DRAINAGE SUMMARY
A numerical drainage summary is used in most project plans. This part of the summary is usually on its own sheet
in a set of Plans and follows after the Summary of Quantities Plan Sheet. Storm drain pipe, drainage structures,
culverts, etc., that are to be placed on the project are listed in a chart format with the quantities needed and then
consecutively numbered. The numbers correspond with the numbers on the Plan View Plan Sheets and the
Drainage Cross Section sheets so that project personnel are able to cross-reference them from one view to another.
Sheet 30 provides an example of drainage quantities, and box culvert information is found on Sheet 21.

DETAILED ESTIMATE
If included in your plan set,the Detailed Estimate lists the required pay item numbers and the quantity for each
item. The Office of Contracts Administration also uses this sheet in preparing the bid proposal.
Figure 4-2. Drainage Summary, Sheet 30.
Remember that these quantities are estimates: the contractor will be paid for the actual quantities used in the
project construction. If there are any items in the contract that are not to be paid for the Department usually lists
them in a separate column labeled “Non-Participatory Items”. The Detailed Estimate plan sheet is listed in
numerical order by the item number.
The pay item number, description, and units are shown verbatim from the Department’s “Pay Item Index”.
Quantities are usually shown in whole units and rounded up unless it is measured “per each.”

INTRODUCTION TO VIEWS
Before going any further, you need to know more about the different viewing angles from which various things are
shown in a set of plans. A view is the way you look at or “see” the different items that are shown on a set of plans.
A view may show something observed from the inside or from the outside. These views are drawn to give you
clear and complete pictures of how the fence, pipe, ditch, or culvert, etc., should be built or placed. To get the
information you need, you must be able to look at the view and “see” what is being pictured. You need to know
from which angle the item is shown. To help you “see” the different views, a chair will be used as the object
pictured because of its familiarity to the reader.
The views here show this chair in the same way that the “real” views show things more appropriate to road and
structure building.
A Plan View is a view from directly above the object. A top view looking down on a chair is
pictured. Dotted lines show parts of the chair you would not see because the seat would hide
the legs and crosspieces and you would not see them.
Figure 5-1.
Plan View
Now look at the set of plans you were given with this material. The first sheet, cover sheet,
shows a Plan View of the entire project. If you were flying in an airplane over this project
and looked down, the plan view is what you would see.
The next set of views shows the elevation or height of the chair from the side and rear. The
view might also be shown from the other side or from the front.
Figure 5-2. Side and Rear Elevations
LONGITUDINAL CROSS SECTION
As you face the side of the chair, a section has been “sliced” away. You see the inside of the seat from the side.
Also note the inside of the crosspieces at the top and bottom of the chair.

CROSS SECTION
As you face the front of the chair, a section has been “sliced” away. Here the chair was sliced across the seat. You
see the layers of the cushion and seat inside the seat. The rest of the chair, shown by dotted lines, is behind the
point where the “slice” was made.
PROFILE VIEW
A Profile View is a lot like a longitudinal cross section of the roadway. Rather than left to right, the profile view
shows the “hills and valleys” of the roadway running along the centerline of the road. It is how the road would look
if you were actually riding on the surface of the road. (Profile view will be further discussed in another chapter,
where you will see example images using the profile view.)

If you missed any of the names of the views, be sure you correct them. Make sure that you understand your
corrections. When you are reading plans, you will not be required to name the views. However, you should know
what the names mean so that when looking at a plan, you will know whether you are seeing the item from the rear
(rear elevation), from the inside (cross-section), etc. This will help you see” the item better.
Of course, the actual views on a set of plans also give dimensions, materials used in construction, and many other
construction details.

The ELEVATIONS generally show the items from the OUTSIDE. These views are
usually very clear drawings, almost like a picture.
The CROSS-SECTIONS always show an inside view - something has been “sliced”
away to show you how the inside part should be. These slices may be made at any
point and would be compared to cutting an apple into two parts with a knife. The next
pages show you how you can sometimes tell where the section is or where the “cut”
was made.
Suppose, for example, sections of a pencil were used to show the inside materials at
different places along the length. See how this is shown in Figure 5-5. The lines be-
tween the letters A-A, B-B, and C-C show where the section is taken. These arrows
on the ends of the lines show which way you’re looking toward when you look at the
section.

STATIONING
Stationing is fundamental to highway plans. A station is the horizontal measurement along the Construction Survey
Line of a project. Distances are measured and points are identified on plans with reference to station numbers. One
hundred feet is equivalent to one station. Highway stationing might be compared with a rope having knots at 100-
foot intervals. The beginning end of the rope would be 0, the first knot at 100 feet would be Station Number 1 and
would be written as 1+00. The second station number would be 2 (which is 200 feet from the beginning) and
would be written as 2+00, and so on.
Station numbers usually increase from the beginning of the project to the end of the project with the convention of
South to North or from West to East. The beginning station of a project can be assumed or referenced to a previous
project. If assumed, it generally starts with 10+00 or 100+00. If there was a project for this road in the past, the
beginning station number may be much higher than the previous example.
Two types of centerline are used. A survey centerline is used to denote the existing alignment, and a construction
centerline is used to denote the proposed alignment. In
this text, a reference to centerline generally indicates
construction line unless the survey centerline is shown
and specifically referenced.
The length of the project in feet may be arrived at by
subtracting the beginning station from the ending
station and multiplying by one hundred.
For instance, if a project begins at station 650 (written
650+00) and ends at station 920 (written 920+00), the
Figure 6.1 How to Think about Stations.
length is (920-650) X 100 = 27,000 feet. This can easily be converted to miles by dividing by 5280 feet per mile.
Think of stations in this way (refer to Figure 6.1).
Just as 12 inches make one foot, 100 feet make one station. It is 100 feet from Station 1+00 to Station 2+00 or
Sta. 493 to Sta. 494, etc.
Answer the question:
6-1 How many feet make up a station?
Chapter 6: Stationing, Symbols
and Abbreviations
Chapter 6: Stationing, Symbols and Abbreviations

HALFWAY
HALF STATIONS
A half station is 50 feet and is located halfway between stations. It is written as +50 after the station number.
Figure 6-2 shows you how station numbers and half stations are written. Any point between two stations is shown
in this same manner.
Figure 6-2. Stationing Example Illustrating Halfway.
For example, two feet forward of station 500+00 is written as 500+02. Numbers less than 10 are indicated as 01,
02, 03, etc. Ninety nine feet ahead of station 500+00 is written as 500+99. Of course, 100 feet ahead of STA.
500+00 is STA. 501+00.
In other words, to show that a point is exactly on a station write it as +00.
To find the distance between any two stations (Except where station equations or equalities are involved) simply
subtract the lower station from the higher one, ignoring the plus sign. You will get the answer in feet.
Example
To find the distance from Station 20+60 to Station
12+80, you can write the numbers without the + sign like
this:
2060
- 1280
780
It is 780 feet from Station 20+60 to Station 12+80.
To check:
From Station 12+80 to 13+00
From 13+00 to 20+00 (7 stations)
From 20+00 to 20+60
20
700
+ 60
780
Please calculate the following:
6-2 The distance from Station 14+10 to 15+00 is feet
6-3 The distance from Station 80+10 to 85+20 is feet
6-4 The distance between Station 48+76.2 and Station 51+24.8 is feet.

On the Plan Sheets, the Station Numbers are usually written along the Construction Centerline. Stationing is
sometimes along a baseline, or along one lane of a multiple lane highway. On a project, AHEAD means in the
direction in which Station Numbers increase (usually toward the END of a project) BACK means in the direction
in which Station Numbers decrease (usually towards the BEGINNING of the project).
Ahead is sometimes abbreviated FWD (for FORWARD), and BACK is abbreviated BK.
On a plan sheet, stationing would be similar to that shown above on Figure 6-3
Figure 6-3. Plan Sheet Stationing.
Please answer the following questions based on this figure:
6-5 How far is it from Station 410+00 to Station 411+00? feet
6-6 How far is it from Station 409+00 to Station 409+69? feet
6-7 How far is it from Station 410+30.17 to Station 412+89.29? feet
6-8 What is the Station Number of a point on Survey C/L 50 feet AHEAD of Station 412+00?
6-9 What is the Station Number of a point 50 feet BACK of Station 412+00?
6-10 What is the distance between Station 411+50 and Station 412+50? feet
Generally, station numbers progress (increase) from WEST to EAST or from SOUTH to NORTH. Since highways
curve and change direction, the above statement is not always true on any one segment of the road.
Just remember that when you say AHEAD you mean toward a higher or “up” station. When you say BACK, you
mean toward a lower or “down” station.

STATION EQUATIONS (EQUALITIES)
Sometimes it is necessary to relate a system of stationing to another system as the connection between two projects
or to account for an increase or decrease in the project’s length due to a change in horizontal alignment.

Equalities are written to describe a point on a Construction C

the station numbers of another system.
Here is one equality:
where the station numbers of one system change to
Station 138+49.42 BACK = Station 114+11.00 AHEAD as shown in Figure 6-4.
The first number is the stationing that is ending. The next number is the beginning station number.
Please answer the following questions:
6-11 If you are walking along the reading the station numbers written on the stakes and these numbers
are getting larger as you go, there is a good chance that you are walking toward what direction?

DETERMINING OF THE PROJECT LENGTH
If there are NO STATION EQUALITIES on the project, you can subtract the beginning station from the ending
station and have the length of the project.
This project ends at station
This project begins at station
Equals the length of the project
701+50.00
409+69.00
291+81.00
Always remember that this length, 291+81.00 (or 291+80 X 100 ft/station) is the length of the project only if no
equalities occur between the beginning and the end of the project. To determine the mileage in a project, you
divide the feet in the project by 5280 ft. (the number of feet in a mile). In this case you would divide 29,181.00 by
5280 and you would get 5.526 miles.

INTRODUCTION TO SYMBOLS
A legend of symbols and abbreviations is not included in the plans. However, certain symbols and abbreviations
are common to a set of highway plans. For example, see Figure 6-6.
Figure 6-6. Symbols for Proposed (Left) and
Existing (Right) ROW Markers.
Refer to pages 28-35 for excerpts from the Department’s Manual of Guidance (MOG) which define the symbols
used by the Georgia Department of Transportation. You should become familiar with the location of the MOG’s
used by your unit.
Introduction to Plan Abbreviations
It is often necessary to abbreviate words on plan sheets. Some standard abbreviations are:
Ahd/FWD = Ahead
Beg = Begin
Emb = Embankment
Hwy = Highway
Pd = Pond
R/W = Right-of-Way
If you run across an abbreviation you don’t understand, turn to Appendix B: Abbreviations in this book.

Introduction to Plan and Profile Sheets
Roadway Plan Sheets depict details of the project’s horizontal alignment. They may be presented in conjunction
with the corresponding profile on the lower half of the sheet called a Plan/Profile Sheet, or the Profile Plan Sheets
will be a separate sheet from the Plan Sheet.
Existing features and roadway design elements such as pavement and shoulder widths, medians, curbs, drainage
elements, tapers, turning provisions, and intersecting roadways are shown on these sheets. All horizontal geometry
is depicted and labeled to fully define the design intent. Separate Plan Sheets may be required for details, which
cannot be adequately shown on the Roadway Plan Sheets.
Both separate Plan & Profile Sheets and combinations Plan/Profile Sheets give a view of the entire project. They
both begin with the lowest station number and the beginning of the project and show the entire roadway ahead to
the end of the project.
PLAN VIEW
Remember that a PLAN VIEW shows the roadway as if you were flying over the project and were looking down.
Turn to Construction Plan Sheet 60. On this Plan Sheet, the PAVEMENT LINES (edges of the pavement) are
shown.
You can also see the SURVEY LINE running from the left of the sheet “AHEAD” to the right of the sheet, then
continuing on the Construction Plan Sheet 61. Above Construction
C
L
, on the Plan Sheet, is considered left of
the
Survey Line.
Below the survey
C
L
is considered right of the Survey Line. Either case will be as though you were standing on the
Survey Line facing ahead.
Remember throughout this course and when speaking of plans that LEFT refers to LEFT of the Construction Line
C
L
and RIGHT refers to the Right of the Construction Line
C
L
, relative to increasing stationing as, shown in the
previous drawing, not the left and right side of the Plan Sheet.

On all construction plans and right of way plans, there is an arrow-like symbol with the point indicating North.
The north arrow will be orientated on the plans to north (not necessarily to the top of the page) and will indicate the
basis of north. Figure 7.2 shows a north arrow referenced to magnetic north and one referenced to the Georgia
Figure 7-2. North-South Arrow.
State Plane Coordinate System West Zone.
The direction of all control and boundary lines is in reference to this North arrow.
The direction of a Construction Line as you are advancing in stationing, as expressed by a bearing, defines the
relationship between the direction of the survey line and a North line. It is customary to orient drawings so that the
North direction is to the TOP of the plan. However, since plans for a complete highway project can seldom be
confined to a single sheet, and must be a series of sheets, it is an accepted practice to make the plans so as to
extend from left to right without regard to the North direction. Look again at Construction Plan Sheet 61 and see
the NORTH ARROW at the top right corner of the sheet. Remember that Station Numbers usually increase from
SOUTH to NORTH.
Circle the correct answer:
7-1 There is an arrow-like symbol with the point indicating (north / south) on all construction plans.
7-2 (Roadway Plan Sheets / Drainage Cross Section Sheets) depict details of the project’s horizontal
alignment.
7-3 Below the Centerline is considered (left / right) of the survey line.

HORIZONTAL ALIGNMENT
Horizontal Alignment consists of tangents (straight sections of road) and curves and is shown on the Plan View.
Plan views are shown on the construction and right of way plan sheets. Construction Plan Sheet 60 shows the
Horizontal Alignment. Construction Plan Sheet 106 shows the Vertical Alignment or Profile View of the same
section of roadway. (Vertical Alignment will be discussed more later).
Point on Curve: A point on a curved segment of roadway
Superelevation: Elevating the outside edge of pavement; this compensates for centrifugal force in a
curved segment of roadway.
Delta Angle: The angle that intersects between the forward and back angle.
Superelevation Rate: Percent slope required on a pavement surface in a curve segment of roadway
Superelevation Runoff: The distance of the transition area where the road goes from a normal crown to
full superelevation.
Tangent Distance: The distance measured from the P.C. (point of curve) or P.T. (point of tangent) to the
P.I. (point of intersection)
Length of Curve: The distance measured along the curve from the P.C. (point of curve) to P.T. (point of
tangent)
Degree of Curve: Angle to express how quickly a curve turns.
Tangent: A straight segment of roadway
Point of intersection: The point where 2 tangents intersect
Curve: Segment of roadway joining two tangent segments
Point of curvature: Beginning of a horizontal curve
Point of Tangent: The end of a curve.

Turn to Construction Plan Sheet 60 and answer the questions:
7-6 At what station does the project begin?
7-7 What do we call the sheets that give horizontal alignment information?
Turn to Construction Plan Sheets 60 and 61 and answer the questions:
7-8 What is the station number of the P.C. for curve 42?
7-9 What is the degree of curve for this curve?
SPIRAL CURVES (Transition Curves) are introduced for the purpose of connecting a tangent with a circular curve
in such a manner that the change of direction and elevation from one to the other takes place gradually. A spiral is
a curve in which the degree of curve increases directly with the length of curve measured from the point where the
curve leaves the tangent. The degree of curve is zero at the tangent and at the point at which the spiral meets the
circular, it is equal to the degree of circular curve.
Spiral curves are always used in railroad work, but are seldom used in new construction highway work.
Figure 7-4 shows the following significant spiral curve stations.

Figure 7-4. Spiral Curve.
SUPERELEVATION
Superelevation of Curves - “superelevate” may be defined as the rotating of the roadway CROSS SECTION in
such a manner as to overcome the centrifugal force that acts on the motor vehicle while it is traversing curved
sections.
In other words, when you are in a curve, your car tends to be thrown to the outside of the curve. So, in order to
overcome centrifugal force, it will be readily seen that the normal roadway cross section will have to be “tilted” to
the superelevate cross section. This tilting is accomplished by means of rotating the cross section about the inner
edge of the pavement for divided highways so that the inner edge retains its normal grade but the centerline grade
is varied. On two (2) lane pavements, the tilting is accomplished by means of rotating the section about the center-
line axis.
The distance required for accomplishing the transition from a NORMAL to SUPERELEVATED SECTION is
called a “transitional runoff” (t) and is a function of the design speed, degree of curvature, and the rate of
superelevation. Transitional runoff is between the beginning of superelevation and the beginning of full
superelevation.
Turn to Sheet 690 (Standard 9028C) and look at the methods for obtaining superelevation for 2 lane pavements and
divided highways.

BEARINGS
A bearing is a method used to express direction. Bearings are used on a set of plans to indicate the magnetic
direction
of the Construction Line
C
L
and the magnetic direction of survey lines and property lines.
Bearings may be referenced to true north, magnetic north or grid north (state plane grid).
Angular measurement is referenced to a circle, and the circle can be broken into more precise measurements of
minutes and seconds. There are 360 degrees in a full circle. There are 60 minutes for each degree and 60 seconds
in each minute. When shown as a compass circle, the circle is divided at North, East, West, and South points into
four section of 90
o
each. The four 90
o
sections are called QUADRANTS and designated: Northeast (N.E.), North-
west (NW), Southeast (SE) and Southwest (SW). This is illustrated by Figure 7-5.
Figure 7-5. Compass Bearing.
All Bearings on the plans must be definitely described as to direction, degrees, minutes, and seconds. It is not
sufficient to describe a line or bearing simply as Northeast or Southwest. The bearing must be described as so
many degrees, minutes, and seconds in the direction in which the line is progressing. The accuracy of calculations
is dependent on exact measurements of distances and bearings. A bearing might be written as N 65º 15’ 30” E.
Bearings are the angular measurements of a line running East or West of due North; and East or West of due
South. Highway bearings do not go beyond 89º 59’ 59”, which is read as 89 degrees, 59 minutes, 59 seconds. After
the aforementioned bearing, they are either due East or due West, or in another quadrant.

PROFILE VIEW (VERTICAL ALIGNMENT)
Now turn to Construction Plan Sheet 106. Look at the profile shown on the sheet. The next few pages in this book
are about the PROFILE VIEW or VERTICAL ALIGNMENT.
A profile is like a longitudinal (length-wise) cross section of the roadway; rather than the left to right width of the
roadway. The profile shows vertical alignment along the roadway at the centerline, survey line, construction
centerline, or another point. The cut or fill on the point shown on the profile does not necessarily mean that the
cut or fill will be the same at this or at any other point on the cross section. For instance, the left side of the
roadway might be in a cut section while the right side might be in a fill section.
Please note that on your reduced plan sheets, in the PLAN VIEW, scale is ½” = 50’ (1” = 100’) in the PRO-
FILE VIEW - VERTICAL ALIGNMENT scale is ½” = 10’ (1” = 20’). Keep this difference in mind when
you look at the VERTICAL ALIGNMENT sections of the Plan Sheets.
On the Profile View, a heavy dark solid line usually shows the proposed Profile Grade Line. It is a regular and
smooth line, just as the top of the roadway will be when finished being built. Look at the Profile Grade Line in the
bottom section of Construction Plan Sheet No. 106. The Original Ground Line is usually shown by a dashed line
and is very irregular since the original ground is irregular (or bumpy) before construction begins.
The primary purpose of the profile (grid) Profile Sheet is to show the relationship between the proposed Profile
Grade and the Original Ground Line.
Circle the correct answers:
7-17 Another name for profile view is (vertical alignment / horizontal alignment).
7-18 A profile can show the vertical alignment along the roadway at the (centerline / cross-over).
7-19 The cut or fill on the profile (does / does not) always mean that the cut or fill will be the same on
each side of the roadway.
7-20 The proposed profile grade line is usually shown as a (solid / dashed line).
Chapter 7: Plan and Profile Sheets

Please refer to Figure 7-7 above and answer the questions:
7-21 In sketch A above, is the area beneath the Grade Line a cut or a fill area?
7-22 Does sketch B, above, show a cut or a fill area?
ELEVATIONS
Elevations are given in feet above a datum. A datum is a reference surface such as sea level. These are numbers
shown on the right and left edge of the Profile Sheet. Looking at Construction Plan Sheet No. 106, look at the
station numbers at the bottom of the page. On each side of the gridline that is drawn from the station number are
two elevation numbers. On the left side of each line is the existing grade elevation at that station number and on
the right side of the line is the proposed grade elevation at that station. Note that these numbers are elevations (in
feet) ABOVE sea level.
The surveyors set reference points of known elevations so that they measure differences in elevations (vertical
distances). Sometimes, markers will be set in trees or in structures and their elevations determined and recorded.
These markers are called BENCH MARKS(BM) and are shown by Numbers (BM #1, BM#2, etc.) These Bench
Marks may be listed on the Plan’s Profile Sheets.

GRADE
Grade is the slope of the roadway. It is expressed as a percentage of the horizontal distance.
That is, a +3% grade means a RISE of 3 feet per 100 feet of horizontal distance.
The grade is considered to be + (positive) or - (negative) depending upon whether it rises or falls as you proceed
along the GRADE LINE in the direction of increasing stations.
Circle the correct answers:
7-23 Elevations are given in (feet / yards).

VERTICAL CURVES
When a road goes over a hill or mountain, it must curve over the top, (crest), or down in a valley (sag). These are
VERTICAL (up and down) CURVES and are shown on the PROFILE SHEETS. They differ from horizontal
curves in two ways.
1. They are parabolic and not circular curves.
2. They define neither vertical and nor horizontal alignment.
A small triangle at the intersection of the tangents shows the P.V.I. or Point of Vertical Intersection. These P.V.I.s
Figure 7-9. Vertical Curves and P.V.I.s.
are similar to the P.I.s (Point of Intersection) for horizontal curves. Look at the P.V.I.s in Figure 7-9, and notice
that the P.V.I.s are NEVER on the actual grade. They will be either above or below grade.
The beginning point of the curve is the PVC (Point of Vertical Curve), and the end of the curve is the PVT (Point
of Vertical Tangent). The length between the PVC and PVT is the length of vertical curve (LVC). Almost always,
the PVC to P.V.I. and P.V.I. to PVT is 1/2 of the LVC. The grade into the P.V.I. is g
1
, and the grade out of the
P.V.I. is g
2
. A negative grade is downhill.
GRADE POINT
The Grade Point is a point where the profile grade line (proposed roadway surface) crosses the original ground
line. Refer to Figure 7-10 below.

7-33 What is the P.V.I. elevation at Sta. 171+00?
7-34 Is the elevation above or below the construction profile?
7-35 What is the percent of grade from Sta. 171+00 forward?
Using Construction Plan Sheet No. 111, answer the questions:
7-36 Is this vertical curve between Stations. 302+50 and 315+50 a sag or a crest?
7-37 Where are the PVC, PVT and the P.V.I. Stations?
7-38 What is the length of this vertical curve?
PAVING LIMITS
Paving limits are the LENGTH AND WIDTH of the roadway to be paved. Look at Construction Plan Sheet 13.
Typical sections for the crossroads are shown. Note that a different cross section is used for tangent and super
elevated sections.
Using Construction Plan Sheet 13, answer the questions:
7-39 What are the tangent section paving limits for the following crossroads?
a. Jackson RD
b. Glad RD
7-40
What are the paving widths?
Chapter 7: Plan and Profile Sheets
50
Construction Limits
The Construction Limits of grading represent either the toe of the fill or limits of the cut slopes or lateral ditches,
berm ditches or surface ditches showing where the limits of the construction should be. These limits of grading are
usually shown as dashed lines on the plans. Looking at Construction Plan Sheet 60, left of the survey line at Station
155+00, you will notice that the letters “F” are part of that dashed line. This indicates that in this area, the limits
will be in a fill section of the terrain. At Station 159+00, left and right of the centerline a dashed line is shown with
the letter “C.” This indicates that in this area, the limits will be in a cut section of the terrain. It is possible to have
cut on one side of the centerline and fill on the other.
FENCING
Fencing is used to physically delineate the right of way of a controlled/limited access roadway or to replace fence
that is along the right of way and personal property. A separate “Fencing Plan” may be included in a set of plans if
the amount of fence warrants it. In most plans, fencing is pictured on the construction plans, as any other
construction item would be, however, the quantities and locations are listed on the Quantity & Summary Sheets of
the plans.
GUARD RAIL
Turn to Construction Plan Sheet 676 of your set of sample plans and note the details for Guard Rail location under
the various conditions. Please note that this one sheet covers only a few of many different conditions. Look at
Construction Plan Sheet 77 near the bridge. The beginning, end and type of guard rail locations are shown. The
Summary of Quantities would also show this information.
RIGHT OF WAY MARKERS
Right of Way (ROW) Markers are used to physically mark the limits of the land, property, etc. that was acquired
for highway purposes on the ground. Normally right of way markers are placed where there is a break in the right
of way such as a PC or PT.
Figure 7-11. Symbols for Proposed (Left) and
Existing (Right) ROW Markers.
Refer to Figure 7-11 for the symbols for proposed and existing Right of Way Markers.
In addition to the symbol used, the locations are flagged with a station number and the distance from the
construction centerline.

INTRODUCTION TO DRAINAGE
Project drainage is accomplished by means of ditches, pipe culverts, box culverts, bridges and minor drainage
structures such as drop inlets, junction boxes, man-holes, spring boxes, endwalls, etc. The amount of water to be
drained determines the type of drainage structure(s) to be built.
Although the terms of culvert and bridge are sometimes used interchangeably, they are different structures.
A culvert is a structure not classified as a bridge that
provides an opening under a roadway - usually for
water drainage. Standard Specifications 101.21
defines a culvert as any structure under the roadway
with a clear opening of 20 feet or less.
A bridge is a structure having a length of over a
twenty foot span that is erected over a roadway,
stream, railroad, depression, or combination of
these.
Each drainage structure is pictured in the Plan Sheets
(Refer to Figure 8-1 at right). Also included in plans will
be a cross section view of each of the drainage structures
to be installed.
PIPE CULVERTS
Figure 8-1. Drainage Table from Sheet 198.
Several examples of pipe culverts are found on Sheet 62. Look near station 192+50. An 18” slope drain (SD) pipe
culvert is used to drain a portion of the median and incorporates a median drop inlet. The pipe flows to a flared end
section at the outfall (left side of road). Note also the profile view. This structure is identified as 10A. Construction
Plan Sheet 214, median drain profiles, shows pipe profiles.
At station 192+29.09 a 5’x4’ box culvert is shown. It is identified as structure 10. A portion of the existing culvert
will be removed and rebuilt to accommodate the road widening. Construction Plan Sheet 202, Drainage Profiles,
shows the culvert profile.
On Construction Plan Sheet No. 198, Drainage Map Plan Sheets, note the culvert details. Station location, skew
angle, size, drainage area, Q

(water flow rate) and receiving stream are shown.
Circle the correct answers:
8-1 Drainage structures (are / are not) pictured in the Plan /Profile Plan Sheet

PLAN VIEW
Look at the PLAN VIEW shown below for the box culvert. Wing Walls and Parapet are not shown. This plan view
shows the culvert from the top. See the centerline of the roadway? Notice that the culvert is on a line perpendicular
to the roadway centerline. This culvert is said to be on a 90 degree SKEW.
Figure 8-5. Plan View of a Box Culvert
This SKEW ANGLE is the angle that the centerline of the culvert makes with the centerline of the roadway as
measured in a clockwise or counterclockwise direction from the centerline of the roadway looking ahead. Look at
the next drawing of a 45 degree skew condition.

8-15 What is the SKEW ANGLE of the CULVERT as shown on the plans at Station 192+24.02?
8-16 Does water flow from left to right, or from right to left in this culvert?

What is the % grade of the old portion of the culvert?
WING WALLS
The barrel of the culvert is the portion of the
structure that conveys the water. Wing walls are
on both ends of the barrel.
The purpose of wing walls is to keep the earth “fill”
above the culvert from spilling into the stream bed.
At right is a section of the wing wall on the previous
drawing of a culvert.

Figure 8-8. Part Plan of Box Culvert on 60 degree Skew.
Wing walls are extensions of the
barrel walls that flare out away from
the stream. Figure 8-9 shows a box
culvert on a 60-degree skew. Notice
how one wing is shorter than the other.
Notice that the length of each wing is
such that the fill slope, as indicated by
the arrowed lines, proceeds down the
slope from the shoulder line of the
roadway.
Therefore, the wing lengths will vary
from culvert to culvert - depending
upon the height of the culvert, the
slope of the fill, and skew of the
culvert. Turn to Standard 2328 on
Sheet 655 of your example plans. Plan
views for different skew angles are
Figure 8-9. Box Culvert on 60 degree skew.
shown. Notice the lengths of Wing M and Wing N. These varying wing lengths are examples of short and long
wings.
The angles that the wings make with the barrel are illustrated in the part plan shown below. Note that the wings are
parallel to lines that cut in half (bisect) the interior corner angles of the culvert.
This procedure is the normal or standard method of establishing the direction of the wings. There are special
occasions (not very often) when the wings are not placed as shown in the “Part Plan” (Figure 8-10) above.
Circle the correct answers:
8-20 The purpose of a wing wall is to keep the earth (fill / cut) from entering the stream.
8-21 Wing wall wings (are / are not) different lengths if the culvert is built on a skew.

BRIDGES
A bridge is constructed over a roadway, stream, or railroad, or a combination of these. Refer to Figure 8-11 below
for two views of a three span bridge over a roadway. Look this structure over carefully.
Figure 8-11. Plan and Elevation Views of a Bridge
Notice these things particularly on the views of the bridge:
1. Look at SPANS A, B, and C - These Spans make up the riding surface of the bridge and consist of a
reinforced concrete deck (slab) supported on steel or concrete BEAMS or GIRDERS that is supported on
the end by BENTS.
2. BEAMS OR GIRDERS - These are placed lengthwise along the bridge (parallel to the Centerline of the
Bridge as shown in the PLAN VIEW) with each end resting on the BENT CAP. They can be made of
steel or concrete. They directly support the roadway slab.
3. BENT - considered to be composed of the BENT CAP, COLUMN, FOOTING, AND THE PILES,
beneath the footing or the Bent Cap and the Pile supporting the cap (in some instances, there are no
columns or footings such as a stream crossing, this is known as a pile bent).
4. BENT CAPS - These are constructed of reinforced concrete and are supported either by means of
concrete or steel PILES or reinforced concrete columns. End Bents normally use Piles.

5. FOOTINGS - These support the Columns and are constructed of reinforced concrete. Footings are sup-
ported either on Piles or firm soil. Footings are not seen once the bridge has been constructed since they
will be covered with earth.
6. PILES - Piles are used when there is no firm material available to support a footing. Steel piles are used in
areas where rock is found; concrete piles are also used in areas where steel piles would corrode easily
such as in coastal areas.
7. SUPERSTRUCTURE OF A BRIDGE - This is the part of the bridge that is above the top of the bent
caps.
8. SUBSTRUCTURE OF A BRIDGE - This is the part of the bridge that is below the top of the Bent Caps.
9. FILL - This is the earth that was required to be placed on top of the existing ground to provide the
foundation for the roadway.
10. FILL SLOPE - This is the slope of the earth which has been placed on existing ground. Fill slope is
normally 2:1 for bridges over highways and streams.
11. CUT SLOPE - The slope beneath a bridge can also be a cut slope. This would be the case where the
bridge is to be built on an existing roadway and the earth below the bridge must be removed to provide for
the roadway below.

Notice the following things shown on the preceding drawing of a cross section of a bridge. Remember that you are
looking at a cross sectional side view of Section A-A.
1. The concrete inserts are placed in the slab when the concrete is poured. The ¾” hangers are then
screwed into the bottom of the insert when the utility is put in place.
2. The utilities are normally placed inside the exterior beams and above the bottom of the beam so they
cannot be readily seen by anyone passing under the bridge in a vehicle.
3. The utilities must clear the steel diaphragm. At times the diaphragm may have to be adjusted up or
down to permit the utility to be placed on the bridge.
4. The lines or conduits are normally located by the dimensions d1, d2, d3, and d4 as shown.
Using the previous bridge cross sections, answer the questions:
8-29 What three utilities are shown in the cross-section?
8-30 How many and what size telephone conduits are shown?
Utility details are more difficult at the end of a bridge. The view below is one looking at the beginning or the
ending end of a bridge which shows the end wall that pipes and conduits must pass through. The bottom section is
a profile view at the end bent.
Examine each diagram carefully.
Figure 8-14. End Bent Elevation and Section
Chapter 8: Drainage
66
Notice the following things shown on the previous End Elevation drawing:
1. The end wall that the utilities must pass through is a reinforced concrete wall that is poured at the same
time as the concrete slab is poured.
2. Note the pipe sleeves that are cast in the end wall for the pipes to pass through. Also, see the opening that
is left for the telephone conduits.
Chapter 9: Utilities
67
Utility plans are used primarily to facilitate coordination between the construction contractor and utility companies
having facilities in the roadway corridor. (The DOT is not involved in the relocation of utilities unless it is done
under a Force Account). These plans show the contractor the approximate locations of existing, relocated, and pro-
posed new utilities aiding the designer and contractor in identifying and/or avoiding conflicts or damage to
facilities. Information is typically obtained from either field survey data and/or the affected utility owner.
Construction Plan Sheet 419 is an example utility plan. Note the gas lines shown before Station 180+00. One gas
line is being relocated, and the other remains in the original location. Also note the Colonial Pipeline dig
notification requirement.
Please identify the following statement as True or False.
9-1 True False Utility plans show the exact location of the utilities of the project.
Plans are also prepared consisting of signs and pavement markings. These plans are normally in the same general
format as the roadway plans.
All permanent roadway signs and pavement markings are placed on the plans as they are supposed to appear upon
completion of the project. See Construction Plan Sheet No. 474 for an example of this.
Chapter 9: Utility Plans
68
Chapter 9: Utilities
Chapter 10:Signing, Pavement Markings, Signals, Highway Lighting & Landscaping
69
All required pavement markings are depicted on the plans including the color, width, and spacing, etc. Call-outs
may be provided to identify the type of each line on Plan Sheet. All required arrows and hatching in accordance
with Department Standards are included. Each arrow may not be labeled but at least one note referencing the
applicable standard is included on each sheet.
A summary of the quantities for any overhead signs typically follow the sign/pavement marking plans. For post
mounted signs, a summary is included with the normal Summary of Quantities Plan Sheets discussed previously in
Chapter 4. It lists the location, installation number, sign codes, etc. for each sign.
TRAFFIC SIGNALS
The signalization plans will show the complete site layout, equipment details, electrical circuitry, signal phasing,
and other relevant data for the installation of traffic signal(s). A separate plan sheet(s) for each intersection
requiring signalization will be provided. A summary table of items needed for each of intersection will be included
showing the name of the item, the method of payment and the quantity to be used for each of the installation(s).
See Construction Plan Sheet 523 for a sample of an installation.
LIGHTING
Highway lighting plans are required when a project involves lighting improvements. The lighting plans are to
provide a comprehensive set of construction details, electrical circuit tabulations, pole data summaries, conduit
descriptions, service point locations, luminaire type and intensity, foundations and details, and all other specific
data relevant to the construction of all lighting related features and components.
If the project consists of high mast lighting towers, it is also required that a soil survey and foundation design is
done.
LANDSCAPING
Projects which require landscaping may require a separate set of plans, at the Department’s direction. These plans
may be included in the roadway contract or as a stand-alone set of plans.
The following information is usually provided in landscape plans:
1. An overall Site Plan and an area map depicting the roadway corridor in relation to the surrounding
environment
Chapter 10: Signing and Pavement Markings,
Signals, Highway Lighting & Landscaping
2. A Planting Plan
3. A Planting Plan Detail

The Traffic Control Plan consists of the plans and specifications developed for each individual construction
project, supplemented by such detailed plans as required by the contract. The Traffic Control Plan complements
the Traffic Control Specifications and the Manual of Uniform Traffic Control Devices (MUTCD).

Chapter 10:Signing, Pavement Markings, Signals, Highway Lighting & Landscaping
Chapter 10:Signing, Pavement Markings, Signals, Highway Lighting & Landscaping
71
Special attention is given to constructability, traffic handling, detours, restrictions to traffic, hours of closure/lane
loss, and responsibility of the contractor. Signing and markings for the Traffic Control Plans are included for
projects such as off-site detours and projects of unusual complexity. Routine projects do not necessarily identify
specific signs, markings, and other devices ordinarily required by the Specifications and Standard Drawings.
Preliminarily, specific Traffic Control Plan sheets for each stage of construction using information from the plan
sheets and intersection and interchange layout sheets are prepared. For each construction stage, plans show the
roadway areas and major drainage structure to be constructed, along with traffic flow patterns, including lane
widths, for the stage. Indicate on the plan areas of temporary pavement, locations of temporary barriers, and any
temporary drainage structures.
Also included on these plan sheets is a narrative of the sequence of construction and of the handling of traffic for
each stage. Where necessary, cross sections of the stage indicating the area to be constructed along with the area to
be used to maintain traffic are included, showing any areas of temporary pavement and any temporary barriers.
If an on-site detour is required, detour plans with cross sections and signing are usually included showing detour
centerline/baseline with curve and alignment data, detour profile, pavement edges, pavement width, construction
limits of the detour, required right-of-way and easements, temporary drainage, and temporary barriers if necessary.
If a road closing and an off-site detour is required, there will be a plan showing a layout of the local roads with the
road closure points and the detour route.
Please answer the following true/false questions:

INTRODUCTION
Steep embankments, ditches, or other exposed surfaces adjacent to a roadway require some means to be taken to
keep exposed soil from eroding away by the action of wind, water, and freezing and thawing action of the weather.
Depending upon the need, erosion control measures such as grassing, silt fence, paved ditches, straw mulch, silt
gates, baled straw, and other devices such as bituminous treated glass fiber, soil reinforcing mats, etc. may be used.
In creating the Erosion, Sedimentation and Pollution Control Plans (ESPCP), references such as the most recent
Department’s Uniform Code System For Soil Erosion And Sediment Control Design Guidelines (Section 161 of the
Department Specifications), the Department’s Manual On Drainage Design For Highways, the Department’s Standard
Specifications Construction of Roads and Bridges, the Department’s Construction Details, and the Georgia State Soil
And Water Conservation Commission Manual For Erosion And Sediment Control in Georgia, to name a few, may be
used in preparing the Erosion, Sedimentation and Pollution Control Plans (ESPCP) and/or package.
WHEN ARE ESPCP NECESSARY?
If the total project disturbs less than one (1) acres only a set of BMP (Best Management Practices) Location Details
are prepared and included in the project construction plans. BMP’s are either structural or vegetative. Structural
measures are structures that control erosion such as rip-rap or paved ditches. Vegetative measures are methods
such as grassing, sod or soil matting.
Figure 12-1. Erosion, Sediment & Pollution Control Plan
Chapter 12: Erosion, Sedimentation, and
Pollution Control Plans (ESPCP)
Chapter 12: Erosion, Sedimentation, and Pollution Control Plans
74
If the total project disturbs 1 acre or more, there will be a standalone erosion control package. This package will
be placed at the back of a set of final construction plans.
WHAT IS INCLUDED IN THE ESPCP?
Included in ESPCP standalone package you should find the following sheets:
Cover Sheet (Construction Type)
General Note Sheet
Drainage Area Map
BMP Plan Sheets (Best Management
Practices)
Comprehensive Monitoring Program
General Note Sheet
Topographical Sheet
Erosion Control Item Construction
Details and Standards
NOI (Notice of Intent)
The BMP Plan Sheets (Figure 12-2, below) contain the recommended types and locations for permanent and
temporary erosion control items. The types of temporary items that should be shown on the plans include silt
control gates, sediment basins, temporary slope drains and sediment barriers, or any other items deemed necessary
and designated as “Temporary Erosion Control” on the uniform code sheets. Any staging to be done on the project
must also be included in these sheets.
The sheets are designed with the same scale and matchlines as the construction plans.
Figure 12-2. Stage 1 BMP Plan Sheet: Location Details.
Chapter 12: Erosion, Sedimentation, and Pollution Control Plans
75
CONTRACTOR RESPONSIBILITIES
The Department of Transportation provides all these plans; however, if there are any changes to the staging, the
contractor is responsible for revising the plans. In addition, the contractor is responsible for the ESPCP for borrow
pits, haul roads, and waste pits.
EXAMPLES
Berm ditches may require concrete ditch paving as erosion control measures. The limits and quantities are noted in
the Summary of Quantities.
Erosion control measures are identified by standard symbols. Measures shown on Construction Plan Sheet 721
include Co (construction exit), Sd3 (temporary sediment basin), and Ch (channel stabilization). These measures are
considered structural BMPs. All measures required for the project are found in the construction details.
Circle the correct answers:
12-1 If a total project is (greater / less) than one (1) acres a set of Erosion Control Plans will be
included in a separate package and attached to the back of the project plans.

Chapter 13: Cross Sections
77
INTRODUCTION TO CROSS SECTIONS
Cross Sections depict the existing ground conditions, including all man-made features, as sections perpendicular to
the construction centerline or baseline. The proposed cross-sectional outline of the new roadway with all its
elements is also shown on the cross sections. Standard Cross Section Plan Sheets are used for showing the roadway
cross sections. The recommended scale is 1” = 100’ or 1” = 200’. If the entire cross section cannot be shown on
one sheet, the sheets may be turned horizontally or more sheets with appropriate match lines shown are used.
Existing ground lines are shown with a dashed line. A note of the existing ground line elevation at the profile grade
line (PGL) just below the ground line is shown. The surface and subgrade of the existing construction such as
pavements, curbs, and sidewalks are shown also with a dashed line. If present, the limits of unsuitable material are
shown. The station number of the section is normally shown in heavy numbers to the right of or below the cross
section.
The proposed roadway template is shown with a solid line. The proposed profile grade elevation is vertically
shown just above the profile grade line. If there are any special ditches, the elevations are normally included as
well. Any and all station equations are shown, even if a cross section may not be plotted at that point.
Roadway Cross Section Plan sheets are usually lined up in a similar way to the list below:
1. Mainline
2. Cross Streets
3. Side Streets
4. Ramps
5. Major Driveways
EARTHWORK
Figure 13-1 is an illustration of typical terrain upon which a two-lane roadway is shown. The illustration can only
be a general picture, but it does convey a third dimension-depth, which a plan view cannot show. Within the
illustration, you can see one item of construction that is changing from station to station and that item is
earthwork (cubic yards of dirt).
Figure 13-1. Typical terrain for a Two-Lane Roadway
Because earthwork is usually a costly item in highway construction, it must be accounted for in the estimate pre-
pared for the project. Since it would be extremely difficult to measure the exact amount of earthwork in a project,
the designer resorts to approximation. This is accomplished by using the Cross Section Plan Sheets.
Remember that the cross section shows what you would see if the highway were cut at right angles to the center-
line.
Chapter 13: Cross Sections
Chapter 13: Cross Sections
78
See the next illustration with examples of cross sections taken in cut and in fill:
The cross section is not always all cut or all fill as shown previously; it may also be part cut and part fill.
Many factors are considered before combining a typical section of the roadway with a cross section of the ground.

The typical section represents an end view of the pavement necessary to carry the type and volume of traffic
established in the highway design.
Figure 13-4. Typical Cross Section along Centerline.
The cross section of the original ground is distinctive for every location along the centerline.
By combining the typical section and the cross section of the original ground, a determination is made of the area
of cut, fill, or both.
Figure 13-5. Cross Section at Station 194+50.
The drawing on Figure 13-6 shows how depth (100 ft.) is multiplied by an averaging of end areas to give a
“volume” answer. The vertical point of reference for a typical section at a particular location along the roadway is
called the profile grade.
Figure 13-6. Volume of Cut.
On projects where the amount of dirt is over a set amount by the Department, the earthwork is paid for as a Cubic
Yard item and not Lump Sum. The District Earthwork Coordinator will verify the cubic yard amount of earthwork
at the beginning of each project. Project personnel will pay up to 95% of the verified quantity of earthwork per the
Standard Specifications until final dressing, etc. is complete.

Upon completion of the final dressing, project personnel should submit to the District Earthwork Coordinator a list
of all areas where the contractor deviated from the plan template with approval of the Department. This form is the
“Earthwork Template Exceptions List”. In the case that the project was built without any exceptions, project
personnel should send a letter stating such to the District Earthwork Coordinator as well.
GRADE
Look at Construction Plan Sheet 236, a Cross Section Plan Sheet, and note that the profile grade elevation (top
elevation) listed for 196+00 is 880.82. The lower elevation is the finished grade for the ditch. The smaller
elevation just below and right of the profile grade elevation is the existing grade. Turn to Construction Plan Sheet
106 and verify the elevations at Sta. 196+00. Now turn to Construction Plan Sheet 8 for the typical section and
compare the required grading template to the plotted cross section. Note that the profile grade is at the center of the
median.
SLOPES
Slopes are usually referred to as “cut slopes” (back slopes), “fill slopes” and “side slopes” (front slopes). A cut
slope is that portion of the roadway between the side drainage ditch and the top of the cut. A fill slope is that
portion of roadway between the shoulder point of the roadway and the toe of the fill. The side slope is that portion
of the roadway between the shoulder point and the adjacent drainage ditch. These slopes are measured as a ratio of
horizontal distance (from and to edge of pavement) versus each foot of decrease or increase in elevation (height).

A 2:1 slope means that for every 2 feet of horizontal distance, the elevation (or vertical distance) increases (cut
section) or decreases (fill section) 1 foot, depending on the type of slope shown on the previous drawing.
Using Cross Section Construction Plan Sheet No. 236, look at Sta. 194+50. Notice that the left side slopes shown
here is a 2:1 slope which is a “fill slope”. Look now at Construction Plan Sheet 8 - Typical Section - and notice
that a fill slope over 10 feet will have a 2:1 slope and that guardrail will be required in this section because of the
depth of fill.

SLOPE STAKES
The following information is a general guide only. Information on these stakes varies with various contractors,
surveyors, and districts. Stakes contain information that tells the Contractor how much “cut” or “fill” is required
from the point of the stake to the ditch line (or shoulder point) of the roadway, depending on whether the stake is in
a cut or in a fill section.
Slope stakes are placed at the point of intersection of the cut or fill slope and the natural ground line.
Figure 13-9. Slope Stake Positioning
Chapter 13: Cross Sections
83
The following information may be shown on the side of the slope stake facing the roadway (this would be the front
of the stake). Refer to Figure 13-10 below.
1. Indicates cut (C) or fill (F)
2. The amount of cut (to the bottom of the ditch) or the amount of fill (to the shoulder point).
3. The distance from the stake to the centerline of the roadway or some other reference line.
4. The rate of slope (such as 2:1)
5. The rate of super elevation (only required when roadway is in a curve section).
Figure 13-10: Station Numbering on Slope Stake.
The station number is shown on the side of the stake away from the roadway or back of the stake. Refer the right
side of Figure 13-10 above.
Often, slope stakes are offset in order to allow the Contractor to perform his work without destroying the slope
stakes. In this case, information should be shown in the same manner as the in-place slope stake except that the
following additional information should be shown encircled on the front of the offset stake.
The distance from the offset stake location to the slope stake location.
The change in elevation between the slope stake location and the offset location as indicated by a + or a -
depending on whether the offset stake location is higher + or lower - than the slope stake location.

INTRODUCTION TO STANDARDS AND DETAILS
“Georgia Construction Standard Drawings” or Standards are generalized construction drawings that are applicable
to most construction projects. Think of Standards as drawings of the normal way the Department of Transportation
wants something built or to be done.
“Georgia Construction Detail Drawings” or Details are a more specific and specialized way that the Department
wants something built. It will usually be something that is not as common a way of doing something on most
construction projects.
“Georgia Special Construction Details” are drawings that are specific and specialized to that project only.
Turn to the Index Sheet and note that Construction Plan Sheets 566-631 are Construction Details and Sheets 632-
707 are Construction Standards and are to be used on the job. Two of these Standard Drawings, Construction Plan
Sheet No. 690 (9028C Superelevation) and Construction Plan Sheet No. 694 (9031S Median Drop Inlet), are
included as examples.
INTERSECTION DETAILS
Intersection details are larger scale views
showing detailed information that could not be
shown clearly on a smaller scale normal Plan
Sheet.
Figure 14-1. Ramp Identification by Letter.
Each ramp in an interchange is identified by a letter designation. These are usually assigned as shown in Figure 14-
1.
Interior ramps or loops are designated with a Subscript A1, A2, etc. or as Loop A, Loop B, etc. At this particular
interchange, Ramps A & B were constructed under a previous contract and would be shown by a dashed line,
indicating existing conditions.

INTRODUCTION
In order to construct any highway, the Right of Way Office must be successful in securing the needed land for
right of way purposes. The Right of Way Office personnel, in most instances, are the first official contact that the
property owner will have with the Department. It is imperative that they also be competent in highway plan
reading so that the plans can properly be interpreted for a highway project to the property owner.
The property owner, above anyone else, is most vitally concerned as to how a proposed highway will affect his
own property. The Right of Way specialist will be required to answer questions concerning the plans in addition to
the general questions concerning the right of way acquisition procedure. On the initial contact with the property
owner, it is of prime importance to properly interpret the highway plans for the owner as well as explain other
phases of the right of way acquisition procedure.
Many times the owner will ask questions regarding ingress (enter in) and egress (exit from) of a proposed highway;
how cuts and fills will affect his property; and how his residence or business will be affected by the highway
project. The farmer is particularly interested in such matters as how his fields and pastures will be divided by a
proposed highway; how his woodland will be affected; how the access to water will be affected; and the
appropriation and relocation of fencing.
Farmers will also ask questions regarding the movement and protection of livestock; how the construction schedule
of the project will affect his planting, growing, and harvesting seasons; and many other questions such as the
appropriation of farm outbuildings and his access to the proposed highway facility. These are only a few of the
questions that a Right of Way Specialist may be asked by a property owner, and the importance of highway plan
reading cannot be stressed too much. If a Right of Way Specialist is hesitant about answering questions regarding
the plans, due to his lack of knowledge, the property owner is apt to become defensive and the Specialist will have
a difficult time in acquiring the property.
In Urban areas, the Right of Way Specialist should be particularly careful in noting the “cuts” and “fills” as
indicated on the plans. Major “cuts” and “fills” can affect locations as to where driveways can be reconnected. It is
entirely possible that the depth of a cut or the height of a fill could eliminate a driveway from being reconnected
even though the project has no limited or control of access.
Urban property owners are particularly interested in such matters as to the appropriation of landscaping, how close
a roadway is to a dwelling or business, driveway reconnections, and parking on a proposed street. Property owners
may have more questions regarding highway construction. In many instances, a property owner will move a
residence or commercial building, which is located within the right of way limits of a highway project to a new
location.
For these reasons, it is imperative that the Right of Way Specialist properly and accurately interprets the plans and
read slope stakes. Highway plan reading is of vital importance to employees of all sections of the Right of Way
Office and all employees should take full advantage of this Plan Reading Course.

RIGHT OF WAY PLAN SHEETS
Right of Way Plans are a separate set of plans from the construction Plans. In going through this section of the
manual, you will find yourself being referenced to a sample set of a Right of Way Plans. You will find those sheets
at the back of your sample pack of Plan Sheets that you received when you began this manual.
In your set of plans, you will find two (2) Cover Sheets for “Proposed Right of Way SR 16Arthur K. Bolton
Parkway.” Notice the Sheet Number differences for the Cover Sheet. The Right of Way information begins on
Cover Sheet Number 1 and finishes on Sheet number 2. The construction plans had one coversheet. Similar to
construction plans, a revision summary sheet is also included (Sheet 3).
Figure 15-1. Right of Way Plan Sheet: Cover Sheets 1 and 2.
Chapter 15: Right of Way
92
While there are similarities between a Construction Cover Sheet (page 4) and a Right of Way Cover Sheet, there
are also differences.
A. Similarities
1. Title of Description - “SR16—Arthur K. Bolton Parkway” in Spalding and Butts counties. It is a federal-
aid project, but the project involved partial limited access and is not on a Federal route. The interstate
improvements are on I-75.
2. Project Number - you will notice that the Right of Way Sheets included in your sample pack of plans is
STP-IM022-1(26) and IM-0000-00(523), the same as the construction plans. Between the time the Right
of Way plans are developed, in the Preconstruction phase of a project, and the time the project reaches the
Construction phase, slight changes may be made, such as an administrative or funding source change.
This could cause a change in the Project Number.
3. Location Sketch - both Cover Sheets have a location sketch on them.
4. Sheet Identification Block - both have blocks in the upper right corner showing the project number, the
sheet number, and the total number of sheets. This set of Right of Way plans has 82 sheets compared with
the 770 sheets in the construction plans.
5. Scale & Length of Project - both have a Scale Box & a Length Box. Sometimes the Gross length of
Construction plans may be different than the Right of Way Length. It is likely that a difference is the
distance needed to tie into the existing construction where the right of way was already purchased and
the new construction.
6. Miscellaneous - both sets of cover sheets have information attesting to their legal status and the basis on
which they are developed.
B. Differences
1. Property Owners - instead of an Index, the Right of Way Cover Sheet shows adjoining parcels and a
number identifying the parcel (rectangular boxes with numbers).
2. Plan View - the Plan View shows the project in the relationship to the affected property lines rather than
the topographical landmarks of a Construction Cover Sheet.
3. Conventional Symbols - notice, particularly, the block in the upper right side. You should pay close
attention to the slight variations among the various types of lines. Refer to Figure 15-2 for an example of
a Conventional Symbol block.
Chapter 15: Right of Way
93
Figure 15-2. Right of Way Plans Sheet 1.
Refer to Sheet 3 of the Right of Way Plans included with your set
of sample plans, which shows the following information. Parcels
are identified by a rectangular box with the name of the owner
underneath (See Figure 15-3 at right). These circled numbers
correspond to the circled numbers on the cover sheet and show
the location of the property owned by that person or company
who will be affected by the project.
Land Lot Lines are thin, dashed lines distinguished from “Req’d
R/W & Limit of Access” lines by the thickness and the letters
L.L.L. (Right of Way Limit Lines are thicker or “blacker” than the
Land Lot Lines (L.L.L.).
Notice the group of four (4) numbers that occur on the Cover
Sheet at the intersection of each of the L.L.L.’s. The numbers refer
to the Land Lots that are adjoining at that point.
Figure 15-3.
Right of Way Plan Sheet 3, Parcel 4.
Using the Cover Sheet, answer the question:
15-1 What are the Land Lot Numbers in which parcel 4 is located?
Chapter 15: Right of Way
94
Figure 15-4. Parcel Required Right of Way.
The letters P & L written on the line identifies property lines. Usually a property line is a thin solid line broken by
a single dash. Notice that the symbol for existing Right of Way is the same as that for a property line, but without
the P.L. This applies to the Right of Way Plans. On Construction Plans, existing Right of Way is shown by long,
broken thin lines. Look at Construction Right of Way Plan Sheet 61, near Station 175+00, either to the right or left
for an example of this.
Using Right of Way Plan Sheet 31, answer the questions:
15-2 Locate the property of Frank Chen, Parcel 37. At what station point and offset does the property
line between Chen and Holcomb intersect the required right of way?
Property information that details the right of way
taking is either shown on the same plan sheet on
which the property is shown, or on a separate
plan sheet. The property being taken will be
described by a point, offset/distance,
station/bearing and alignment. The point
reference is shown on the right of way plan
sheet. The offset/distance is the offset from
centerline, and the distance is to the next right of
way point. The station/bearing is the station of
the point, and the bearing is to the next right of
way point. The alignment indicates what
construction centerline is being used (mainline
or side road). Using Figure 15-4 from KC25004
to KC25005 is 48.252
feet at a bearing of N 88° 34’ 56.99” E. Point
KC25004 is 38.630 feet left of Rehoboth Road at
Station 10+75.
Similar information is also given for required
drive easements, temporary easements,
construction easements, and limited access.
On this project, there are a number of
construction and/or drive easements. An easement is giving permission to temporarily use a part of someone’s
private property to perform an act of construction for a set amount of time.
By looking at the Right of Way Plan Sheets, you can identify most of the locations at a glance. They are marked
with diagonal shadings. To see one of these locations, look at Right of Way Plan Sheet Number 3 at Parcel Num-
ber 3.
Using Right of Way Plan Sheet 31and 32 (data on Parcel No. 37) to answer the questions:
15-3 How much right of way is required on Frank Chen’s property (Parcel No. 37)?
15-4 How many feet of limited access is required for the same property?

centrifugal force that acts on a motor vehicle. The difference in elevation between the edges of a traffic lane
applied where curves in the roadway alignment are used.
SUPERSTRUCTURE OF A BRIDGE - that part of the bridge that is above the top of the bent cap.
SURFACE COURSE - the top layer of the pavement structure.
SURVEY LINE - a line established by surveying to mark the location of a highway as the boundaries of property.
SYMBOLS - a conventional sign used in writing or printing which relates or represents quantities, items, or
things.
T
TANGENT - any straight section of the roadway (alignment). A tangent to a curve is a line that touches the curve
at one point and is also at right angles to the radius at the point of contact with the curve.
Appendix A: Definitions
106
TEMPORARY EASEMENT - an easement granted to the Transportation Department on a temporary basis
usually for a specified time and specified purpose. A right to use the land during construction which, upon
completion, the land reverts back to the owner.
TOTAL TAKE - the acquiring of a property in its entirety for highway purposes.
TRAVEL LANES - lanes in which vehicles move.
TYPICAL SECTION - a cross sectional view of a roadway showing how the roadway would appear after the
roadway is completed.
U
UTILITY - physical plants and operating facilities which provide public or private utilities consisting mainly of
communication lines, electric power lines, gas lines, water mains, sewer mains, and other pipe lines, and the
supporting structures for these facilities.
V
VERTICAL - perpendicular to the plane of the horizon or to a primary axis.
VERTICAL ALIGNMENT - see “Profile View”.
VERTICAL CURVE - a parabolic curve drawn tangent to intersecting grade lines to provide a smooth transition
from one grade to another.
VIEW - the way you look at or see” the different items that are shown in a set of plans.
