Plan Sheet Library

These drawings were developed and are supported by the Headquarters Design Office; however, they are provided “as is”. The user assumes full responsibility for the plan’s adequacy to address a specific construction situation and for any alterations to the drawing by the user.

When a drawing from this Plan Sheet Library is used in a contract document, a Professional Engineer must review the plan and accept full responsibility for its contents in the manner prescribed by the Washington State Department of Licensing.

The Plan Sheet Library provides drawings (Details) of:

  • Site-specific details
  • Experimental designs that are precluded from adoption as Standard Plans
  • Former Standard Plans which no longer meet current design policy criteria, but are offered for maintaining existing installations (not meant for new WSDOT installations)

These drawings each have a narrative explaining the intended use and some of the possible impacts associated with its usage.
