Demolition, Tunnel Opening, & Waterfront Impacts.

Alaskan Way Viaduct and waterfront

The Alaskan Way Viaduct is permanently closing. Before the new tunnel opens, crews need 3 weeks to build essential connection points.

The Alaskan Way Viaduct (AWV) was built in the 1950s as an elevated portion of the SR 99 highway along Seattle’s waterfront. Its age coupled with decades of wear and tear have made the structure vulnerability to earthquakes. Demolition is critical to public safety. WSDOT will begin tearing it down as early as this fall.
