Bridge Design Memos
Bridge Design Memos (BDMs) provide guidance and best practices to designers to efficiently and consistently implement Caltran's Structure Technical Policies (STPs) and design specifications. BDMs include guidance and best practices from previous Memos to Designers (MTDs) and Bridge Design Aids (BDAs) and supersede any similar content in the MTDs or BDAs. The BDMs have been organized to closely align with the organization of the AASHTO LRFD Bridge Design Specifications.
