Seattle’s Alaskan Way Viaduct is now history

Updated 11/22/19: Late on Thursday we published a video that uses drone footage to capture the dramatic sight of Seattle's waterfront without the viaduct:


For nearly seven decades, the Alaskan Way Viaduct dominated the downtown Seattle waterfront. Today, tucked out of view of the waterfront it so long divided, the final pieces of the viaduct were quietly plucked from a steep hillside near Pike Place Market.

Viaduct demolition was an exceptionally challenging project, as the roadway stood perilously close to nearby buildings, live traffic on Alaskan Way, major underground utilities and a critical rail corridor. We kept people and goods moving while the contractor, Kiewit Infrastructure West, and their demolition subcontractor, Ferma Corp., completed the job with no injuries and no significant damage.

This historic milestone caps a year of accomplishment that began with opening the new State Route 99 tunnel in February. Although demolition is now complete, Kiewit will continue working into 2020 on filling and sealing the Battery Street Tunnel and rebuilding Seventh Avenue North.
