Niagara Tunnel - May Report

May 2nd 2010 -

The TBM is at 6,882 meters (22,578.4 feet). The TBM has been shutdown for scheduled maintenance and to allow for the launch of the arch forms into the tunnel. On May 11th, the widening of the new air vent shaft will begin.

Well, the fire didn't slow them a bit! They are having lots of fun zooming through the cap rock at a tremendous speed. No word on how well they are doing with the splatching of the overbreak, but something is going on, since it looks like they will start slipforming the final liner. If they use the nuclear waste funds to pay for this, then we are golden. :)
