Though the Highway 99 tunnel is still about a year and a half from opening, WSDOT is ready to talk about what happens once it’s open – the demolition of the Alaskan Way Viaduct. Published on the AWV website today:
With tunnel boring complete, we’re deep in the planning stages for demolition of Seattle’s Alaskan Way Viaduct. On Thursday, we’ll launch an online open house to show what’s ahead and give the public a chance to comment on the work to come.
Removing the seismically vulnerable viaduct will be the most visible change to Seattle’s waterfront in decades. The demolition work begins after the new State Route 99 tunnel opens, which is estimated for early 2019.
WSDOT has successfully completed this type of work before. In 2011, we demolished the viaduct’s southern mile and built a new road in its place. However, the remaining section of the viaduct is more challenging, as it is much closer to buildings, businesses, homes and the busy Colman Dock ferry terminal.
Demolition is expected to take up to nine months, with the viaduct being demolished in sections to minimize localized disruptions. This contract will also involve other project elements, like filling in the Battery Street Tunnel and reconnecting several surface streets across Aurora Avenue North, which will take additional time.
Several weeks before the new tunnel opens, WSDOT will shift Alaskan Way to the west of the viaduct, which will allow traffic to move along the waterfront before and during viaduct demolition. This new video below explains some of the planning for the demolition.
