Section 6: Bridge Design

Anchor: #i1001800

Overview

Design of structures is performed in conjunction with the design of the approach roadway, and traffic forecast requirements for bridges are the same as those for the geometric design of roadways. Traffic volumes are not used to determine the design load of the structure.
