Crews begin unloading Bertha off ship

SEATTLE — Crews on Elliott Bay started unloading some of the 41 pieces that make up Bertha on Saturday.

Bertha, a tunnel boring machine, is a 900 ton load and workers only got a small fraction of it.

Over the next two weeks, the parts will make their way to a work site. Then it will take a few months to assemble Bertha.

“What you’re going to see here today is a lot of smaller stuff. The big show is going to be when we lift the cutter off and move that over to the job site,” Preedy said.

KIRO 7 Eyewitness News spoke with Matt Preedy, a Washington State Department of Transportation program administrator, about the machine.

Bertha will be used to dig a tunnel under downtown Seattle to replace the Alaskan Way Viaduct.
