WSDOT crews will close S Dearborn St and narrow 1st Ave S to two lanes beginning Thursday, September 12 in order to remove the remaining section of the Alaskan Way Viaduct. S Dearborn St will be closed for up to 10 days while crews remove the viaduct overhead. Plan ahead and prepare for impacts to travel during this period of the #SeattleSqueeze.

It’s time to make a plan and prepare for new routes if you’re driving or taking transit.

This closure will cause unavoidable disruptions to traffic. If you are traveling to and from SR 99 and points south and west of downtown, consider alternate routes or ways of getting around, including exiting SR 99 at Spokane Street, using transit or taking the King County Water Taxi.

Some King County Metro buses will reroute while South Dearborn Street is closed.

The contractor will pull their work zone back from Alaskan Way to open the full four lanes for people driving during this closure.

What’s next for the Seattle Squeeze?

This month will also bring demolition to the section of viaduct around Marion St and changes for passengers arriving at Colman Dock. This construction is just one component of the #SeattleSqueeze as large public and private construction projects continue to impact how we get around. This will all be worth it.

We’re continuing to work closely with our partners at WSDOT, King County Metro, Sound Transit, and the Port of Seattle to keep people and goods moving safely through the Seattle Squeeze. Plan ahead and learn more at www.seattle.gov/traffic.
