The January closure of the Alaskan Way Viaduct in downtown Seattle — also known as State Route 99 — was another step in a long reclamation project that will eventually remove the highway and repurpose the land it occupies.
According to the Washington State Department of Transportation, removing the viaduct will be completed in three stages: site preparation, demolition and site restoration.
Now that Seattle's long-awaited SR 99 tunnel has opened to traffic, demolition of the Alaskan Way Viaduct can begin, moving the $3.3 billion, 30-project endeavor one step closer to the projected 2021 completion.
Seattle celebrated the opening of SR 99 with a party for the public, including a fun run, bike race and walking tour of the tunnel — an opportunity 70,000 people signed on for.

Aug. 6 marked the beginning of an important project that must be completed before the Alaskan Way Viaduct can be removed.

Three years after the tunneling machine dubbed “Bertha” began work on a 2-mi. (3.2 km) tunnel beneath the city of Seattle, the machine has passed the half-way point. Bertha pushed past the Pike Place Market on Sept. 30, successfully excavating more than 4,635 ft.
