Highway System Plan update – Open house

Welcome to the Washington State Department of Transportation (WSDOT) online open house for the Highway System Plan (HSP) Update.

The Highway System Plan is WSDOT’s blueprint for preserving, maintaining, improving and operating interstates, US routes, and state routes in Washington.

This is your opportunity to provide input on how to invest funds to improve the future highway system.

Thank you to everyone who attended our virtual public meetings, scenario workshops, and equity workshops over the past few months. We are looking forward to using your feedback to inform the Highway System Plan. If you haven’t shared your thoughts with us yet, be sure to watch the video and take the opinion poll below!
