Bertha is getting back to work this week, but will she come out roaring or will it be more like a whine? That's what critics are wondering as "Bertha," the giant boring machine being used to dig a tunnel under Seattle is brought back to life.
Bertha had several mechanical problems over the past year that left it sitting idle for almost that long. According to Q13 Fox, the Washington State Department of Transportation says the rotary drill will have to be stopped periodically to allow it to cool off, as it has a tendency to overheat.
