The Elephant in the Room: Is Bertha toast?

Seattle's multi-billion dollar Viaduct replacement tunnel is in trouble — and has been, for a year. The shaky waterfront portion of Highway 99 has been settling into the loose soil beneath it. Buildings and streets above the new tunnel have sunk as well, and cracks have opened up in some streets and foundations in Pioneer Square.

Digging the deep shaft that will give workers access to our tunneling machine's damaged drill head may be making things worse. At best, the complex task figures to delay the tunnel's opening by nine months, pushing it back to August 2107.

So how close is this monster tunneling project to the land of boondoggle? Can Bertha be reached (safely) and repaired?

Crosscut contributors — and Bertha afficionadoes —  Matt Fikse-Verkerk and Knute Berger joined Steve Scher at Zeitgeist Coffee in Pioneer Square, just blocks from the troubled project, to ask: Is Bertha toast?
