Are you ready?

Viaduct closing for good on Jan 11

It’s happening! The Alaskan Way Viaduct will be closing permanently later today.

This will be the longest major highway closure ever experienced in the Puget Sound region. At the end of the closure, the new Highway 99 tunnel will open, providing a direct route from the stadiums to the Space Needle.

During the three-week closure, as well as subsequent work, significant traffic disruption is expected and travelers are urged to pursue alternative options to their normal commute. WSDOT, the City of Seattle and King County Metro have been actively working to provide information on mobility options and travel tools. These include enhanced traffic operations and monitoring, increased transit options, and innovative web and mobile information tools.

The closure will allow WSDOT to complete the highway and eight ramps connecting the new tunnel to Highway 99 and local streets. The removal of the viaduct is anticipated to begin in February and take approximately six months.

The Transportation Policy Board was briefed on the closure at its meeting yesterday. View the presentation or watch the meeting discussion (starting at about 1:21:47).
