Part of the machine which will create the SR 99 tunnel [May. 11th, 2013|04:38 pm]
Russell Brunelle



It's the largest-diameter tunnel boring machine in the world.

The cutting mechanisms attach to the bottom side of the tilted cylinder you see here; the blue things on its top are the motors.

Cutting should begin in mid-July.
