This Manual contains NDDOT Bridge Division policies and procedures for the design, evaluation, and rehabilitation of bridges. Except where noted, the design provisions herein employ the Load and Resistance Factor Design (LRFD) methodology set forth by AASHTO.

Use of this Manual does not relieve the design engineer of responsibility for the design of a bridge or structural component. Although Bridge Division policy is presented here for numerous situations, content of the Manual is not intended to be exhaustive. Therefore, use of this Manual must be tempered with sound engineering judgement.
