Delaware Aqueduct Bypass Tunnel Boring Now Complete

In August 2019, the 6.8 m (22.3 ft) diameter Robbins Single Shield TBM broke through after excavating at instantaneous penetration rates up to 6 m (20 ft) per hour. Image credit: NYCDEP In August 2019, a 6.8 m (22.3 ft) diameter Robbins Single Shield TBM accomplished an epic feat of tunneling. The unique machine, designed to statically hold up to 20 bar pressure, had bored below the Hudson River for 3,794 m (12,448 ft) over 582 days with penetration rates of 6 m (20 ft) per hour. The tunnel depth—ranging from nearly 270 m (900 ft) deep where the TBM was launched in Newburgh, New York to over 180 m (600 ft) deep at the exit shaft—the water volume and pressure were significant challenges. “Things went really well. The machine did what it was supposed to do, the rock behaved, the learning curve for running the machine was reached before we hit any problems. We hit a curve, and the crew got used to it—we hit good limestone, and then harder rock. We also hit water, and we learned how to deal with that,” said Ted Dowey, Portfolio Manager for the New York City Department of Environmental Protection (NYCDEP), project owner. Successfully surmounting the obstacles required unique TBM desi...
