The Tunnel Boring Machine is here!

On Friday, July 10th, major parts of the Tunnel Boring Machine (TBM) arrived at the South Shaft site from Japan.
The TBM will be used to bore the tunnel between the North and South Shafts. It will be assembled this summer and will begin tunneling in late summer/early fall.
The photograph is of the TBM cutter head.
