Bridge Design Manual
1.1 Manual Description
1.1.1 Purpose
The Bridge Design Manual (BDM) M 23-50 is a guide for those who design bridges for the Washington
State Department of Transportation (WSDOT).
This manual supplements the AASHTO LRFD
Specifications. It explains differences where it deviates from the AASHTO LRFD Specifications.
It contains standardized design details and methods, which are based on years of experience.
The Bridge Design Manual is a dynamic document, which constantly changes because of the creativity
and innovative skills of our bridge designers and structural detailers. It is not intended for the design of
unusual structures or to inhibit the designer in the exercise of engineering judgment. There is no substitute
for experience, good judgment, and common sense.
