Work continues at the Gateway Tunnel cofferdam site off Pier 66 on the North River, with funding for the rail tunnel project restored by court order earlier this year. Tug work is spread across a range of locally active towing firms and Thursday morning found Haugland Group towboat Emma Rose maneuvering a crane barge while Stasinos’s Brynn Courtney delivered a deck barge loaded with cement silos.

The cement will be mixed with mud and water and pumped to the bottom inside the cofferdam to reinforce the riverbed so that tunnel boring machines can eventually move through. The work is gradually shifting from last-year’s mid-channel site and is now closer to the Manhattan shoreline.
