Bertha Triumphs: Tunnel Boring Machine Will Cross the Finish Line Today

KIRO reports that contractors expect Bertha “to complete her journey underneath downtown Seattle” today, April 4.

KIRO also features a timeline of WSDOT’s Alaskan Way Viaduct project marking the ups and downs Bertha experienced along the way. “Maybe it’s not on par with the pyramid of Giza, or even the Great Wall of China, but the tunnel that Bertha just bored beneath Seattle is still a marvel,” the station observes.
