SR 99 Closure - Reminder

Post Date:12/20/2018 10:00 AM

Beginning January 11, 2019, after the evening commute, the Washington State Department of Transportation (WSDOT) will be closing SR 99 through downtown Seattle for approximately 3 weeks to realign the highway into the SR 99 tunnel,  and permanently close the SR 99 Viaduct. Additional ramp closures mean this work could create up to six weeks of traffic disruption.

No matter how you commute, or where from, you should expect significant delays during these closures and be prepared for crowded buses, trains, water taxis, and light rail. All buses coming into or through downtown Seattle will face delays. Twelve southwest routes and five northern routes will be directly affected by the closure. 

Commuters are urged to start thinking NOW about how their commute patterns will be impacted and how their commutes will need to be adjusted:

  • Shift your travel time to avoid the busiest times on the roadway
  • Start or join a carpool, vanpool or van-share
  • Use transit, particularly light rail and King County Water Taxi
  • Stay off the road: work from home, postpone discretionary trips, take time off
