The Alaskan Way Viaduct Program has posted two video simulations to show the proposed replacements for the Alaskan Way Viaduct.

The simulations show the current design concept for the proposed SR 99 bored tunnel and the new Alaskan Way surface street on the Seattle waterfront.

See the simulations here.

The first video shows the current design concept for the proposed SR 99 bored tunnel. The drive-through starts at the tunnel’s south portal, which is near the stadium district and the Port of Seattle’s terminals, and takes you to the exit in the north, onto Aurora Avenue North.

Along the way, there are ramps at either end of the tunnel that will allow drivers to access the downtown street grid from SR 99, as well as the new street connections that will be built over the tunnel’s portals.



The the second video shows what the waterfront would look like. The state plans to build a new Alaskan Way boulevard in the footprint of the current viaduct.

The new road would connect to Elliott and Western avenues, which is important for those traveling to the northwest section of the city, and will provide access to downtown and SR 99.

The state says removal of the viaduct will allow creation of new public open space on the waterfront.
