The Engineering Publications office functions include researching, reviewing, and distributing Washington State Department of Transportation technical manuals and publications. Most of the department's primary technical manuals, used by transportation engineers
and technicians, are available from the Index.
Effectively immediately, Engineering Publications will begin charging state sales tax for publications purchased by consumers per RCW 82.08.02525. Please include sales tax for your order using the sales tax rate for your shipping (city) address. If you have questions, please contact us.
All manuals can be downloaded and printed using a pdf format without charge.
