You can almost hear the roar of an X-Wing starfighter.
The Washington Department of Transportation posted drone footage from inside the new Highway 99 tunnel, showing the partially constructed roadway and the innards of Bertha’s giant cutting head.
The tunneling machine is more than one-third of the way through its 385-foot journey under the Seattle viaduct. WSDOT estimates the closure of the elevated roadway between South Spokane Street and the south end of the Battery street tunnel will last approximately two weeks.
The drone begins at the opening near the Alaskan Way Viaduct and zips through the lower and then upper decks of the tunnel during a worker shift change, according to the video description.
