The Viaduct is shutting down forever on January 11. It will then be replaced with a massive underground tunnel.

It started with Bertha, boring underneath downtown Seattle and generating enough dirt to fill CenturyLink Stadium — about 85,000 dump trucks worth of soil if you're doing the math.

In February 2019 the demolition of the Alaskan Way Viaduct begins and is expected to take six months. That will spell the end of Seattle's double-decker elevated freeway which first opened nearly 66 years ago.

So, where will all that debris—the concrete and steel— end up? We answer that question on the next SoundQs episode.
