Results WSDOT strategic plan

The agency’s roadmap for Washington’s transportation future, Results WSDOT, focuses on six goals: strategic investments, modal integration, environmental stewardship, organizational strength, community engagement and smart technology. Through a culture of continuous improvement, WSDOT is building a more efficient, effective and accountable government for those we serve. This strategic plan aligns with the Governor’s Results Washington initiative.

Results WSDOT supports the six transportation policy goals adopted by the Legislature in RCW 47.01.012 which includes safety, preservation, mobility, environment, stewardship, and economic vitality. These goals are interdependent and support the overall vision for all transportation agencies (like WSDOT) in the state.

As WSDOT delivers transportation services, we also work to identify lowest cost solutions and practical design principles to get the most efficient use of limited resources, preserve environmental quality, improve fish passage, identify clean transportation opportunities to address climate change and aggressively pursue agency reforms to improve our performance.

WSDOT’s diverse programs and projects are supported by more than 6,800 full-time employees, including engineers, vessel captains, maintenance technicians, environmental specialists, planners, and many others. We take pride in our workforce and strive for excellence and integrity in everything we do.
