What is the WTP?

The Washington Transportation Plan (WTP 2035) is a comprehensive and balanced statewide transportation plan that establishes a 20-year vision for the development of the statewide transportation system, from state highways and ferries to sidewalks and bike paths, county roads, city streets, public transit, air and rail. WTP 2035 identifies significant statewide transportation issues, and recommends statewide transportation policies and strategies to the legislature and Governor (RCW 47.01.071(4)). By law, WTP 2035 is required to be consistent with state’s growth management goals, reflect the priorities of government, and address regional needs, including multimodal transportation planning.

It was developed and adopted by the Washington State Transportation Commission in January 2015 and delivered to the governor and legislature. Phase 1 contains 11 key findings and 151 recommended actions.


WTP Phase 2 – Implementation, in process

It will implement recommendations from Phase 1 for the development of the state’s multimodal transportation system. That system includes public roads, ferries, public transportation, aviation, freight and passenger rail, ports, and bicycles and pedestrian facilities. Phase 2 will also implement the Governor’s Executive Order 14-04: Washington Carbon Pollution Reduction and Clean Energy Action; which directs WSDOT to develop, adopt, and implement the multimodal, federally-compliant, long-range statewide transportation plan. Phase 2 will also encompass the six goals of Results WSDOT, the agency’s strategic plan. It is scheduled to be completed by December 2017 and will be approved by the WSDOT Secretary.

WTP 2035 is based on the following six transportation policy goals established by the Legislature:

PRESERVATION: To maintain, preserve, and extend the life and utility of prior investments in transportation systems and services.

SAFETY: To provide for and improve the safety and security of transportation customers and the transportation system.

MOBILITY: To improve the predictable movement of goods and people throughout Washington state.

ENVIRONMENT: To enhance Washington’s quality of life through transportation investments that promote energy conservation, enhance healthy communities, and protect the environment.

STEWARDSHIP: To continuously improve the quality, effectiveness, and efficiency of the transportation system.

ECONOMIC VITALITY: To promote and develop transportation systems that stimulate, support and enhance the movement of people and goods to ensure a prosperous economy.
