Welcome to the Washington Transportation Plan 


The Washington Transportation Plan (WTP) establishes a 20-year vision for the development of the statewide transportation system. WTP is based on the six transportation system policy goals established by the Legislature: preservation, safety, mobility, environment, stewardship, and economic vitality (RCW 47.04.280). The WTP is done in two phases:

WTP 2035 – Phase 1 (Policy) was completed by the Washington State Transportation Commission (WSTC) and it provides the statewide policy recommendations to the Legislature. The Commission’s most recent update is available at www.wtp2040andbeyond.com.

WTP Phase 2 – Implementation 2017-2040 was updated by the Washington State Department of Transportation (WSDOT) and replaces the 2007-2026 long range transportation plan and meets federal and state requirements. It implements key policy recommendations for the development of the state’s multimodal transportation system through four focus areas and eleven action items.
