In Construction
The two new tubes under the Hudson River—the Hudson River Tunnel—are estimated to be complete in 2035. Then the existing North River Tunnel will be rehabilitated one tube at a time, estimated to be finished in 2038.
As of October 2025, five of ten contract packages for HTP are in construction and two are inactive procurement.
The Tonnelle Avenue Project will reach substantial completion in 2025, ensuring the first tunnel boring machines can launch in New Jersey in 2026.
GDC expects to award the Hudson River Tunnel contract in Q4 2025 and the NJ Surface Alignment Project in Q1 2026.
RFQs for two additional contracts will be released in the coming months.

The Hudson Tunnel Project (HTP) involves construction of a new, two-track Hudson River rail tunnel serving New York Penn Station and the rehabilitation of the existing Superstorm Sandy-damaged North River Tunnel (NRT).
The HTP will improve reliability and redundancy in this critical section of Amtrak’s Northeast Corridor (NEC). At present, approximately 450 Amtrak and NJ TRANSIT trains pass through the NRT on a typical weekday, servicing nearly 200,000 daily passenger trips across the Hudson River. With such a high volume of rail traffic, the operational flexibility the HTP will provide is crucial not only to rail service, but also to the mobility and economic vitality of both the region and the nation as a whole.
The NRT was built by the Pennsylvania Railroad and completed in 1910. The tunnel consists of two, single-track, electrified tubes, which serve as the only passenger rail connections between Manhattan and New Jersey and the rest of the NEC. In October 2012, the tunnel was inundated with millions of gallons of salt water during Superstorm Sandy, leaving behind corrosive chemicals which continue to degrade the concrete tunnel liner, bench walls, and other systems that support Amtrak and NJ TRANSIT train operations.
A Final Environmental Impact Statement (FEIS) for the HTP was prepared by the Federal Railroad Administration (FRA), Port Authority of NY & NJ, and NJ TRANSIT, and a Record of Decision (ROD) issued in 2021.
In 2022, the Gateway Development Commission (GDC)—a partnership among Amtrak, the State of New York and the State of New Jersey—assumed the role of Project Sponsor for the HTP, and in 2023, early construction works began on both sides of the Hudson River. In New Jersey, overhead bridge and utility relocations commenced at Tonnelle Avenue in North Bergen, and in New York, the construction of Hudson Yards Concrete Casing (HYCC-3) began in Manhattan. The first major civil construction project of the HTP, Hudson River Ground Stabilization (HRGS), kicked off in May 2024.
Today, work is underway across five construction sites in New York and New Jersey. The Tonnelle Avenue project is on track for completion before the end of 2025, and tunnel boring machines (TBMs) are scheduled to launch from the Palisades portal in 2026.
The Hudson Tunnel Project is fully funded by $12 billion in federal funding and $4 billion in local funding shared among the States of New York and New Jersey and the Port Authority of New York and New Jersey.
