First tunnel boring machines complete testing for Hudson Tunnel Project
The Gateway Development Commission (GDC) has completed manufacturing and factory testing of the first two tunnel boring machines (TBMs) for the Hudson Tunnel Project, marking a major construction milestone for the $16-billion rail infrastructure program.
The custom-built TBMs will now be shipped to New Jersey for on-site assembly at the base of the Palisades in North Bergen. Components of the first machine are scheduled to arrive in January, with on-site assembly and testing expected to take about three months. Tunnel excavation is slated to begin in spring, while the second TBM is expected to arrive in early 2026 and start boring in the summer.
The two machines will simultaneously bore the parallel tunnel tubes on the New Jersey side of the Hudson River, constructing roughly one mile of new rail tunnel. Each TBM is designed to advance approximately 30 ft per day while installing the concrete tunnel lining behind it.
GDC also reported progress across multiple active construction fronts, including completion of a bridge structure beneath Tonnelle Avenue, excavation of the TBM launch box, initiation of major concrete work at Hudson Yards, deep soil mixing in the Hudson River, and ongoing ground stabilization and shaft construction in both New Jersey and Manhattan.
Officials said the completion of TBM manufacturing and testing keeps the Hudson Tunnel Project on schedule as it enters its next major construction phase.
