First Boring Machine Launched for New Hudson River Rail Tunnel

Officials gathered in North Bergen, New Jersey, on Monday to ceremonially launch the first tunnel-boring machine for a new passenger rail connection between New Jersey and Manhattan.

The 1,680-ton machine is undergoing final testing and is expected to begin cutting through the Palisades Cliffs in the coming days. A second machine is due to launch soon afterward.

New Jersey Governor Mikie Sherrill said the launch marked the first time in more than a century that a rail tunnel has been dug through the cliffs. She described the machine as a mechanical marvel assembled from nearly 100 complex components, which workers had spent months reassembling and testing.

Jason Green of the Gateway Development Commission explained how the machine works: a rotating cutterhead at the front cuts through rock, while a shield pushes the machine forward. Debris is carried through the centre of the machine on a conveyor belt and out the back.

The $16 billion project has survived years of political and financial setbacks. Federal support was frozen in 2025, prompting a brief construction suspension, but a federal judge blocked the funding freeze and ordered payments restored while the legal dispute continued.

New York Governor Kathy Hochul said many had doubted the day would arrive, citing "a lot of fits and starts," but added that the project was back on schedule. Senate Minority Leader Chuck Schumer called it an incredible engineering project, saying the machines would cut through very hard rock. Senator Cory Booker said constituents often asked why crossing a single river was so difficult when rockets and submarines could travel to space and the ocean depths.

Officials say the tunnel is vital to the national economy. The existing 116-year-old crossing serves about 200,000 passengers daily. Sherrill said the surrounding region generates 20% of the country's gross domestic product and described the rail corridor as its main artery.
