Alaskan Way Viaduct removal scheduled to begin in February

Posted on Dec 4 2018 1:18 PM

Opening Seattle’s new SR 99 tunnel early next year will set the stage for the biggest transformation of Seattle’s central waterfront in a generation. The demolition of the Alaskan Way Viaduct is scheduled to begin in February 2019 and take approximately six months to complete, as work crews move along the structure, removing it section by section.

Our new video provides an overview of the work to come:

The contractor conducting the work, Kiewit, has been finalizing their work plans and schedule, and we'll have new information to share on the Viaduct Demolition section of our website this week. Demolition work is unavoidably disruptive, but the waterfront, Pioneer Square, and other nearby neighborhoods will remain open throughout the project.

Removing the viaduct, however, is just one part of the work to come. After the new tunnel opens, Kiewit will also begin filling and sealing the Battery Street Tunnel, and rebuilding Aurora Avenue North between Harrison Street and Denny Way. Those projects are both scheduled to conclude in 2020.

Live or work near the viaduct or Battery Street Tunnel? Join us for drop-in sessions this week and next. WSDOT and Kiewit project staff will answer questions about the work to come, aided by display boards and handouts. All three sessions will have the same information, covering every part of the project.
