During the SR 99 closure be prepared for traffic delays and full buses during peak travel times Check out the travel options below that can help everyone get around until the new SR 99 tunnel opens.

Work from home—the only way to commute in your slippers

If possible, working from home (or teleworking) is the best (and comfiest) option during the SR 99 closure. You'll save time and stress while helping reduce the number of people sitting in traffic. Work with your employer to see if working from home during the closure is an option.

If you need to come into work, consider arranging a partial-day schedule that avoids peak travel times—usually 6 a.m. to 10 a.m. and 3 p.m. to 7 p.m. Reducing the numbers of days you’re in the office helps reduce traffic.

Are you an employer interested in learning more about ways to incorporate teleworking into your existing commuter program or even doing a test of a program during the closure? Contact us about our WorkSmart program—a free consultation service from King County Metro.

Can’t work from home but still want to work closer to home? Try a coworking location in your neighborhood.

Bus, light rail, Sounder train—getting there together

Riding Transit

Twelve bus routes have changed paths following the Alaskan Way Viaduct closure. They go to the same places and serve the same or similar stops, but travel times could be longer. Check out a set of videos to help you understand the routing for the south end Metro bus routes impacted by SR 99 closure coming into downtown Seattle: 21x, 37, 55-56-57, 113, 120, 121-122-123, 125 and C Line.

See the route maps here (including translated content).

Expect buses, trains and light rail to be more crowded than usual, especially during peak times from 6 a.m. to 10 a.m. and 3 p.m. to 7 p.m. If you need to travel in or near Seattle, consider shifting your travel times. Anticipate longer travel times and unpredictable traffic delays.

Avoiding peak times will make for a more comfortable (and quicker) riding experience while freeing up space for others who can't shift their schedule. It's also a great excuse to grab a bite after work at that spot you've been meaning to try.

To help keep yourself informed about transit services sign up for alerts.

Coming in from the North End?

Accessing downtown Seattle from the north during the closure will be difficult, especially on SR 99. If you're looking for a sure way to dodge traffic, it might be time to try taking Link light rail or the Sounder train.

If you are traveling from farther north, try the Sounder train. It runs from Everett to Seattle with stops in Mukilteo and Edmonds. There are four trips into town in the morning and four back north in the evening.

Link light rail runs from the University of Washington through Capitol Hill and to downtown.

Bus service is available, but traffic will affect travel times and passenger capacity. If possible, plan a few backup routes and travel options in advance so you can adapt to day-to-day changes.

To see how SR 99 buses are accessing downtown at the north end during the closure take a look at the northend pathways map.

Heading in from the South End?

With especially heavy traffic into downtown during this time, it might be time to try taking Link light rail or the Sounder train.

Link light rail starts at Angle Lake and travels through SeaTac, Tukwila, the Rainier Valley and SODO into downtown and on to the University of Washington, with stops along the way.

The Sounder train starts in Lakewood and makes stops in Tacoma, Puyallup, Sumner, Auburn, Kent, Tukwila and Seattle.

Bus service is still an option, but will be facing heavy traffic and extra crowding during peak travel times.

No matter what commute option you choose, keep a backup or two in mind so you can adapt to day-to-day changes.

Bike or walk—good for you, good for traffic

When traffic is slow, it's hard to beat biking or walking. Traveling on your own power builds exercise into your day and can clear your head for a fresh start or end to your work time. Here are some tips:


Try biking for all or part of your commute. If biking the whole trip isn't right for you, try riding to your bus, train or water taxi. Park your bike for the day at a rack or locker. Learn how to load your bike onto transit here. Check out our bike maps and resources to get started or set your favorite mapping app to the bike layer.

Many buildings have secure indoor bike parking, showers and clothes lockers. Ask your Employee Transportation Coordinator or building manager for more information.

On-street bike parking is available throughout downtown Seattle. Check out this commute portal map, click on the 'Public Bicycle Parking' tab then zoom in to your location.

Visit our bikes and transit page.


Bikeshare is available throughout Seattle with rates starting at $1. Download a local bikeshare app, find an available bike on the map, unlock and off you go. Then lock it up.

Bikeshare is particularly great for connecting to or from a bus, train or water taxi and during the SR 99 closure providers are offering discounts. From Jan. 11 to Feb. 15, JUMP will be waiving the $1 unlock fee. Starting Jan. 9, Lime will be offering $1 off rides starting in West Seattle with the code PMCLIME.


Sometimes even walking is faster than sitting in traffic. Try getting on or off your bus at the edges of downtown to get around places where traffic is slower than usual. Getting on your feet might be just what you need to get out of a traffic jam!

Driving—it won't be easy, but it will be possible

If you do have to drive, consider carpooling and be sure to account for heavy traffic. Register on and find carpool partners. If that isn't going to work for you, consider leaving much earlier or later to avoid the rush. Peak travel times are usually 6 a.m. to 10 a.m. and 3 p.m. to 7 p.m., but are expected to begin earlier and end later than typical rush hours during the closure.

I-5 Express Lanes

WSDOT uses Express Lanes to assist the flow of traffic during busy travel times. Contrary to common belief, the I-5 Express Lanes, and some on- and off- ramps between Northgate and downtown Seattle, can be used by single occupant vehicles.
