Euclid Creek Starter and Exit Tunnels

A 300-foot long tail tunnel running in the opposite direction to ECT was required to provide a future connection to the 2nd phase Dugway Storage Tunnel. A 125-foot long, 30 foot diameter starter tunnel was constructed as the TBM launching chamber. At completion of the TBM drive these tunnels required a cast in place final liner originally designed with a single layer of steel bar, which was later changed to Barchip’s synthetic fiber reinforcement.
