Niagara Tunnel on the Road Again

July 8th 2010 -

At the beginning of the day shift, the TBM is at 7,152 meters (23,464 feet). The TBM is averaging 15 meters daily There is no appreciable overbreak. The Invert Concrete Carrier is at 5,075 meters (16,651 feet). The Arch Concrete Carrier is at 112 meters (367 feet).

Yeah! It's amazing what an infinite amount of money can accomplish! The TBM has virtually been replaced, and they are on the move! The main roof liner seems to be stuck, must be that pesky overbreak...
