WSDOT technical manuals are updated continuously and revisions are issued periodically. It is the responsibility of the user of these materials, regardless of their format or means of transmission, to determine that they are using current versions. The publications on this page are the most recent versions of the manuals we distribute from Administrative and Engineering Publications.
Electronic Only manuals are noted by "EO" after the manual title. These manuals are no longer available in printed form from the Department of Transportation. Please check the General Store for availability of printed publications if you are not a WSDOT employee.
WSDOT employees can order manuals from Administrative and Engineering Publications.
If you have questions or suggestions on how we can improve our publications or our website, please e-mail us at: engrpubs@wsdot.wa.gov
