The end of the road is in view: WSDOT selects contractor to tear down Alaskan Way Viaduct

SEATTLE -- The Alaskan Way Viaduct's days are officially numbered.

We knew that already with the new SR-99 waterfront tunnel getting close to completion, but the next step was taken Wednesday as the WSDOT has chosen its contractor to demolish the viaduct.

Kiewit Infrastructure West bid $93.7 million to not only tear down the viaduct, but fill in the soon-to-be-defunct Battery Street Tunnel and reconnect the city streets that have been severed by the current SR-99.

“We are excited to be so close to removing the seismically vulnerable viaduct and ushering in a new era on Seattle’s waterfront,” Brian Nielsen, WSDOT’s Alaskan Way Viaduct Replacement Program Administrator, said in a statement released to the media.

An exact date to begin demolition hasn't been set yet, but it's expected to begin later this year. A more precise schedule will be released once the contract is finalized.

WSDOT officials say the viaduct will be permanently closed before the new tunnel is expected to open in the fall. Workers will then realign SR-99 and the ramps at the tunnel portals. Once the tunnel opens, limited demolition work on the viaduct could begin in late 2018 with the majority of demolition completed in 2019.

The Battery Street Tunnel project will take about two years, WSDOT officials say, then Thomas and John Streets will be reconnected to the other side of the old SR-99.
