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.

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

Effectively immediately, Engineering Publications will no longer sell printed department manuals or publications to the general public, contractors, consultants, cities, or counties. This service is now available through the Washington State Department of Printing’s Fulfillment Center. Printed copies of the Department of Transportation’s most requested manuals are available through an online service called the General Store. This is a secure Web site. Once you have established an account with them, you may purchase any product they have available..

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.
