Filling of Seattle's Battery Street Tunnel using viaduct rubble could begin as early as next week
Now that a thorough cleaning has been completed, the now-unused Battery Street Tunnel is closer than ever to becoming a thing of the past, when it will be filled with debris from the Alaskan Way Viaduct demolition.
Before that can happen -- which could be as early as next week -- sewer lines will need to be installed and other utility work needs to be completed.
When that is done, rubble from the demolition will be trucked in and deposited inside the tunnel, the Washington State Department of Transportation said in a blog post. Crews have already cleaned the tunnel to remove vehicle exhaust and have removed mechanical and electrical systems from inside the tunnel.
"The Battery Street Tunnel, like the Alaskan Way Viaduct, is seismically vulnerable," officials said in the blog post. "Decommissioning it improves surface mobility by allowing three blocks of Seventh Avenue North (formerly Aurora Avenue North) to be rebuilt into a two-way surface street with four-way intersections and bus lanes."
