Structure Technical Policies (STPs)
Structure Technical Policies (STPs) supplement design specifications by addressing areas not covered; expanding requirements based on successful past practices; and implementing more recent innovations. STPs include policies from previous Memos to Designers (MTDs) and Bridge Design Aids (BDAs). STPs supersede any similar content in the MTDs or BDAs. Content is limited to that which if not followed, requires a Design Exception by the California State Bridge Engineer.
