SEATTLE — It’s been a few weeks, but we still don’t know what is blocking Bertha’s path.

A senior engineer told the Seattle Times that workers have checked the soil in six spots in front of the SR-99 tunneling machine but haven’t bumped into anything yet.

Contractors will likely send workers into Bertha’s flooded front end on Thursday to see if they find anything.

The 7,000 ton machine is 60 feet underground working on a new tunnel that will replace the Alaskan Way Viaduct.

    It's a boat that was sunk before they built over Old Seattle.

    I thought that the reason DOT bought this thing was because it can drill through anything and everything…..next thing just use explosives and blow whatever is in the way all to hell.

    Shows how unknown the soil conditions really are in that area, makes me wonder if it really is viable for for a tunnel. Anyone seen the movie Daylight?
