The Standard Plans Manual offers these options:
- Plans for viewing or printing as pdf files
- Technical commentary for viewing or printing as pdf files
Each plan contains PDF version of the plan and a ZIP file containing the CAD files (.dgn & .dwg) of the respective plan.
An underlined plan identifier, for example B-5.20 (PDF 33KB), is a technical commentary for that plan.
The next Standard Plans Manual revision, due approximately September 2025, will be posted to this page.

General information for all Standard Plans
Changes in laws, regulations and policies prompt these revisions, as do the requirements to keep pace with evolving technology and to align with policy documents from federal transportation agencies. See the overview of the Standards process and see how the Standard Plans are prioritized.
Future Standard Plans are those approved for publication and are awaiting the next installment of a revision package.
Evolving standards and barrier standard plans
WSDOT continues, in cooperation with FHWA, our implementation of the AASHTO Manual for the Assessment of Safety Hardware (or MASH). MASH is the new national standard for crash testing and design of new roadside barrier. With the MASH implementation schedule now complete, the Design Office has recently removed a number of standard plans that do not represent MASH compliant design, while new designs are in development and published over time. In the meantime, these plans can be viewed on the Plan Sheet Library, and may be incorporated into projects upon review and on a case by case basis.

Slow down on ice and snow.
It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.
Carry chains, practice installing them.
Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.
Pack your winter car kit.
Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
