NEW YORK — Construction of the Hudson River Tunnel project on the Northeast Corridor is on the verge of halting because of the withholding of federal funds, the agency overseeing the project said on Tuesday, Jan. 27. It also notes a stop to construction will increase the risk that the 116-year-old North River Tunnel — actually a pair of single-track tunnels beneath the Hudson — could fail before the new tunnel can be completed. The full project calls for restoration of the existing tubes when the new project is completed, increasing NEC capacity. “It is Chuck Schumer and Democrats who are standing in the way of a deal for the Gateway tunnel project by refusing to negotiate with the Trump Administration,” Desai wrote. One of two tunnel boring machines has arrived in New Jersey and the other is to be shipped next month.
