The Bridge Design Manual chapters are available in an on-line format from the WSDOT Engineering Publications Office.

Updates to Manual
We are continuously improving the way we do business. From time to time design memorandums are issued as interim updates to the Bridge Design Manual. These memos supercede the contents of the Bridge Design Manual.

Customer Survey
We are in the process of updating the BDM as part of our transition to the AASHTO LRFD Bridge Design Specification. We have put together a short survey to gather feedback from engineers who use the BDM. Please help us make the BDM the best that it can be by taking a few minutes to fill out the survey.
