Make the most of your holiday weekend travels by planning ahead

WSDOT Holiday Travel Chart shows expected traffic congestion May 24 and 25 on US 2 between Skykomish and Stevens Pass.

Memorial Day weekend is often the unofficial start of summer, and many people are expected to take to Washington state’s highways. To help with your travel plans, we released travel charts for the holiday weekend last week. The charts include the best (and worst) times to travel on major routes like Interstate 5 between Olympia and Tacoma, US 2, I-90 and the I-5/U.S.-Canadian border.

Most state highway construction work is suspended through the holiday weekend – including Friday, May 24 – to ease congestion. Please stay alert for new lane shifts or other work zone staging areas that may remain in place. And please give any emergency repair crews plenty of space to work safely.

Snoqualmie Pass

Even though there is no planned construction on I-90 over Snoqualmie Pass, you should still expect delays with increased holiday traffic. Text message alerts about significant delays are available by texting the words “WSDOT Snoqualmie” to 468311.


In the Puget Sound region, weekend toll rates will be in effect on Monday, May 27, on the State Route 520 bridge and SR 99 tunnel. The I-405 express toll lanes will be free and open to all drivers on the Monday holiday. Out-of-town travelers, including those using rental cars, can learn about toll roads and temporary account payment options on the Good To Go! visitors page.

"Know before you go"

We recommend following these tips whether traveling across town or statewide:

FERRIES: Nearly 350,000 riders expected for Memorial Day weekend travel

Washington State Ferries expects to welcome approximately 350,000 people aboard over the Memorial Day holiday weekend.

As the crewing situation improves, Washington State Ferries’ cancellation rate has been cut in half over the past year. That’s good news for the hundreds of thousands of people that will take to the Salish Sea for the unofficial start of the busy summer travel season. State ferry ridership is expected to approach 350,000 over Memorial Day weekend, from Thursday, May 23, through Monday, May 27.

Holiday schedules

On Memorial Day, May 27, there will be a few holiday schedule changes for the Anacortes/San Juan Islands, Edmonds/Kingston, Mukilteo/Clinton, Point Defiance/Tahlequah and Port Townsend/Coupeville routes. The Seattle/Bainbridge Island run will operate a Saturday timetable, and the Fauntleroy/Vashon/Southworth route will run on a two-boat weekend timetable. Holiday sailings are marked on the schedules for each route.

Travelers can download the WSDOT mobile app for up-to-the-minute service information, including rider alerts and a real-time map to track the boats.

Increase in completed sailings

WSF has been vigorously recruiting, hiring and training employees to increase crewing during a global shortage of mariners. Because of those efforts, the system completed 99.1% of sailings scheduled in January through April of this year, up from 97.8% during the first four months of 2023.

Keep an eye out for Ski to Sea racers in Whatcom County

Nothing says Memorial Day weekend in Whatcom County quite like the Ski to Sea race. The annual event, a seven-leg relay from the Mt. Baker Ski Area to Marine Park in Bellingham, is scheduled for Sunday, May 26. Teams of eight will compete in cross country skiing, downhill skiing/snowboarding, running, road biking, canoeing, cyclocross biking and sea kayaking, and a couple of those legs could affect your travel plans.

SR 542/Mount Baker Highway will be closed east Silver Lake Road in Maple Falls from 7:15 to 11 a.m. Sunday. You also could see riders crossing SR 547/Kendall Road and SR 544 in Everson, where law enforcement officers will control intersections. Please keep your eye out for competitors, follow instructions from officers and plan for delays around the race route with extra traffic in the area.

Construction, maintenance and special events

Road work ahead

We often have special events and roadwork taking place in the Northend, including construction projects, maintenance and repairs. We always try to minimize any effects to travel, but sometimes it is necessary to close a lane to do the work or create a safe work zone for our crews.

While we aren't doing a lot of roadwork this week, our crews will still be out monitoring and keeping the roads safe. If you spot them, slow down and give them space to work! A huge thanks to our crews for all their hard work through the holidays.
