Three-week closure of SR 99

Three-week closure of SR 99

When the new SR 99 tunnel is ready to open, travelers will experience the longest major highway closure the Puget Sound Region has ever seen. The closure is currently planned to begin on Jan. 11, 2019.

WSDOT will need to close SR 99 through downtown Seattle for approximately three weeks to realign the highway into the tunnel. During this closure both the viaduct and the tunnel will be closed. This disruption is unavoidable due to the large amount of work involved in re-aligning SR 99 with the new tunnel. Additional ramp closures mean up to six weeks of traffic disruption.

#REALIGN99 IS COMING JAN 11: START MAKING YOUR PLAN

We will need everyone's help during the closure to avoid gridlock. Commuters and employers, start thinking now about how you can change commute patterns:

  • Shift your travel time to avoid the busiest times on the roadway
  • Bike or walk to work or school
  • Start or join a carpool, vanpool or vanshare
  • Start a telecommute program for employees
  • Use transit, particularly light rail and King County Water Taxi
  • Stay off the road: work from home, postpone discretionary trips, take time off
  • Be prepared for your new route when the closure ends and the new tunnel opens.

More options and ideas: We have developed a handout of ideas and resources for changing your commute or travel habits.
