Nine Day Alaskan Way Viaduct Closure Coming

Nearly 110,000 cars travel across the Alaskan Way Viaduct each day. Next month, those drivers will be pushed onto other streets as Washington Department of Transportation crews demolish the southern end of the Viaduct.

Starting on Friday, October 21st, the Viaduct will be closed for nine full days.

“The nine-day closure of the viaduct will significantly affect traffic across the Puget Sound region,” said Matt Preedy, WSDOT Alaskan Way Viaduct deputy program director. “We realize that not everyone can completely change their commute. But for those who have a choice, options such as vanpooling, carpooling or other forms of transportation can help you avoid long delays.”

Northbound closure details:

Northbound SR 99 between the West Seattle Bridge and South Royal Brougham Way will be closed around the clock from 7:30 p.m. Friday, Oct. 21, to 5 a.m. Monday, Oct. 31.

Southbound closure details:

Southbound SR 99 between the Battery Street Tunnel and West Seattle Bridge will be closed around-the-clock from 7:30 p.m. Friday, Oct. 21 to 5 a.m. Monday, Oct. 31.
