The last holiday weekend of the summer typically brings additional traffic, so planning ahead and allowing extra travel time is even more critical as Labor Day approaches.
Travelers can consult the Washington State Department of Transportation’s holiday-weekend traffic volume charts to help plan the best times to travel on key routes. If possible, altering travel to less busy times can improve individual trips and help keep all traffic flowing more freely. Those venturing out on land or sea can also use several WSDOT tools to keep updated throughout the trip.
Know before you go
- Check WSDOT’s mobile app, Facebook page, multiple Twitter accounts and online tools for traffic information and ferry schedules. (When driving, have a passenger check online updates or pull over to safe place before using electronic devices).
- Call the 511 travel information hotline. For out-of-state callers, it’s 1-800-695-ROAD (7623).
- Pre-program vehicle radios to 530 AM and 1610 AM for highway advisory radio alerts.
- Carry extra water, snacks and other supplies in case you’re delayed along the way.
Statewide construction halted, but expect holiday travel delays — especially on passes
To ease congestion statewide, WSDOT suspends most state highway construction work during the holiday weekend, starting Friday, Aug. 30, through Monday, Sept. 2. This includes Interstate 90 from North Bend to Vantage, but some construction zone detours will remain in place. Traffic is always heavy over Snoqualmie Pass on summer weekends – especially Labor Day – so travelers should allow extra travel time or consider traveling during non-peak times, typically early in the day or later in the evening.
In the Puget Sound, weekend toll rates will be in effect on Monday, Sept. 2, on the State Route 520 bridge. The Interstate 405 express toll lanes will be free and open to all drivers on the Monday holiday. Travelers can learn about toll roads and rental car tips on the Good to Go! visitors page.
Washington State Ferries passengers should expect heavier traffic during the holiday weekend and reservations are strongly recommended for the Anacortes/San Juan Islands; Anacortes/Sidney, British Columbia; and Port Townsend/Coupeville ferry routes.
- Reservations can be made online or by calling 888-808-7977.
- Visit the schedules and best travel times website for more details.
Other travel considerations
Travelers planning to avoid highway congestion by traveling via train, personal aircraft or transit also should factor the holiday into their plans:

- Check the status of state-operated airports online or by calling 800-552-0666.
