Highway System Plan

Over half of the vehicle-miles traveled each year in Washington occur on state highways, and planning helps keep the wheels turning on these facilities. People travel the state highways in personal vehicles, vanpools and buses to reach jobs, schools and services. Some also walk and bike along and across state highways to reach these destinations. Truckers use state highways to move goods. The state highway network supports successful businesses and healthy communities. WSDOT is committed to providing safe, reliable and cost-effective transportation options for the traveling public.

Draft 2024 Highway System Plan now available for review

Check out the draft HSP plan (PDF 5.6 MB) and let us know what you think over at our online open house!

WSDOT has developed a new draft HSP that recommends new revenue for state highways over the next 20 years be dedicated first to adequately funding preservation and maintenance, with remaining funds balanced between safety and efficiency strategies and highway expansion projects at a 2:1 ratio. This draft recommendation provides for a resilient state highway system that is:

Sound

All bridges and highways remain open and are maintained in working condition.

Safe

Fewer crashes on state highways by providing safer travel spaces for all modes.

Smart

• Healthier Environment. Removal of fish passage barriers, fewer vehicle miles traveled, and decreased greenhouse gas emissions.
• More equitable outcomes. Agency investments and policy decisions that are equitable and inclusive.
• More walking, bicycling, and rolling. Closure of most active transportation gaps on, next to, or across highways.
• More travel options. Reduction of commute trips by coordinating with cities, employers, and transit to add or support more modes and travel options.
• Smoother transportation operations. More effective handling of crashes, information, and low-cost solutions.
