Alaskan Way shifting from under viaduct this weekend, expect traffic delays

Alaskan Way Viaduct

SEATTLE – Alaskan Way will be closed on Saturday from 8 p.m. to 10 a.m. on Sunday as crews begin prepping to take down the viaduct in early 2019.

This weekend Alaskan Way will move west of the viaduct, with the new alignment featuring two lanes in each direction from King Street to Union Street. Moving the travel lanes west allows the Washington state Department of Transportation to keep the street open when work begins to remove the viaduct.

Western Avenue will be the primary detour route and access to Colman Dock will be from South Jackson Street (entrance) and Yesler Way and Marion Street (exits).

Drivers are encouraged to plan their routes accordingly this weekend.

“Something I really want to make sure folks are aware of is when this traffic shift happens on Alaskan Way, it’s going to go right in front of the Seattle Ferry Terminal at Colman Dock, so that means folks who are driving in or out of Colman Dock – whether you’re in a bicycle or car, or even if you’re just walking – there’s going to be lots more traffic,” said Broch Bender with the Washington State Ferries. "So, we want to make sure folks look both ways and pay attention."

Expect additional closures on Alaskan Way near Pike Street:

The crosswalk at Pike Street will close on Saturday and reopen by Sunday.

Pedestrians will be detoured one block south to Union Street.

When Alaskan Way reopens, it will be narrowed to one lane, controlled by flaggers from Union Street to north of Pine Street.

By Monday morning, once paving and pavement markings are installed, Alaskan Way will open to one lane in each direction and remain like this for another six weeks to allow for utility and signal work.

Alaskan Way around Pike Street will expand to two lanes in each direction towards the end of November.

Starting with the commute Monday morning, folks are really going to see a difference,” Bender said. “There’s going to be more traffic and we want to make sure people stay safe.”
