# 5 - Plan and Elevation

## 5.1 General

A. This drawing is the general layout of the bridge in plan and elevation views.

B. See SDMEx-7.

## 5.2 Scales

A. Draw Plan and Elevation views to the same vertical and horizontal scale if possible. In some cases a larger vertical scale larger than horizontal is required. More than one sheet may be required.

B. Do not indicate the scale on the drawing.

C. Select scales selected providing 100% drawing legibility when reproduced to 11-inch x 17-inch prints. See the CPCH for additional information. See Chapter 2
for recommended scales.

## 5.3 Plan and Elevation Drawing

Show the following items:

A. The bridge in both plan and elevation views entitled with "PLAN" and "ELEVATION". This is mandatory for 30% and subsequent submittals.

B. The elevation (vertical) scale.

C. All vertical and horizontal geometry including:

1.) Horizontal alignment. (Horizontal curve data or Bearing of tangents.)

2.) Vertical Curve Data.

3.) Profile grade lines.

a. When the bridge is on a tangent grade, show the grade and station and elevation of the nearest P.I. or P.V.I.

b. When the bridge is on a vertical curve, use a profile grade diagram showing as a minimum the percent slopes, the station and elevation of the P.I., the length of the vertical curve, the location of the Bridge and a reference to the horizontal control line to which it applies See Chapter 2
.

D. Location of profile grade line and roadway alignment.

E. Stations at begin and end of bridge and approach slabs. Stations at centerlines of bents or piers. Stations at intersections of centerlines of roads. Stations on lower roadway, stream, railroad or other physical feature at the location on the structure plan along the stationing line for the structure.

F. Span lengths and overall length of bridge.

G. North Arrow, direction of flow for water crossing and direction of stationing.

H. Skew angle at bents and intersecting base lines.

I. Roadway width, barrier width, shoulder width, median width, sidewalk width, out-to-out width, width of widening and width of removal (including removal of slope protection).

J. Critical locations and dimensions of horizontal and vertical clearances.

K. Location of expansion and fixed bearings.

L. Traffic data (for each facility, if grade separation): design speed, present and design year (+20), percentage of trucks and direction of traffic.

M. Boring Locations.

N. Utilities, sanitary and storm sewers, telephones, etc.

O. Right-of-way lines (roadway, railroad, etc.)

P. Limits of slope pavements, sand cement riprap or rubble riprap.

Q. Edge of shoulder.

R. Embankment slope.

S. Toe of slope.

T. Berm width.

U. Existing ground and finished ground profiles.

V. Low, mean and high water elevations as appropriate.

W. Guardrail in Plan and Elevation views.

X. Bridge-mounted Lighting, Signs and Signals.

Y. Distance to milepost from intersection of railroads.

Z. Existing bridge numbers.
