TBM Making Progress in Tunnel!

The tunnel boring machine (TBM) at the South Shaft location is making progress creating the New Crystal Springs Bypass Tunnel!

As of this week, the TBM has mined 401 feet so far, and with the starter tunnel distance included, that brings us to 532 feet or 12.4% complete.

Here is a photo from the bottom of the South Shaft.
