alaskan way viaduct

On the eve of a two-week closure of the Alaskan Way Viaduct, former Washington Governor Chris Gregoire said she’s confident the tunneling project under Seattle’s waterfront will ultimately succeed.

The viaduct is closing to allow the tunnel-boring machine known as Bertha to dig underneath the double-decker structure. Under the original timeline the tunnel was supposed to be open by now and the viaduct long ago torn down.
