Know before you go this Labor Day weekend and plan ahead for heavy traffic on the state’s major highways.

One way to beat the crowds is to check out our predicted travel volumes on the state’s major travel routes.

To help drivers navigate holiday traffic, we gather data to provide the best times to travel on Interstate 90 over Snoqualmie Pass, US 2 over Stevens Pass, Interstate 5 through Thurston and Pierce counties, and I-5 between Bellingham and the U.S./Canada border.

You can also check out our nifty tools that provide traffic camera images, ferry schedules and a map of highway incidents and closures. Other handy items include the WSDOT mobile app, Twitter and Facebook.
