Hudson Tunnel Project Timeline: 15 Years in the Making
From its 2011 origins to federal funding fights and active construction, here's a complete timeline of the Hudson Tunnel Project's turbulent history.
The Hudson Tunnel Project has been fifteen years in the making, and its path from blueprint to active construction has run through political fights, natural disasters, and a federal funding freeze that shut down work and idled a thousand workers earlier this year.
Here is how the project got to where it stands today.
The effort began in February 2011, one year after the cancellation of the Access to the Region’s Core project, which would have added rail capacity under the Hudson River. The initiative launched under the name Gateway Project with an estimated price tag of $13.5 billion. Then Superstorm Sandy hit in October 2012, flooding the existing North River Tunnels and making the case for new infrastructure even more urgent. Amtrak went to Congress in December 2012 requesting $276 million to repair damaged infrastructure that would also support Gateway’s planned right-of-way.
The Gateway Development Corp. was created and announced by Amtrak in November 2016. Within a year, though, federal support was crumbling. In December 2017, a Trump administration official at the Federal Transit Administration labeled Gateway a “local” project, a designation that effectively put federal funding in question.
The project gained its footing again under the Biden administration. Federal approval came in May 2021. By July 2022, New York and New Jersey each agreed to cover 25 percent of costs, with the federal government committing to the remaining 50 percent. The Gateway Development Commission put the total cost at $16.1 billion and set a completion date of 2035 for the new tunnels, with renovation of the existing North River Tunnels to finish by 2038.
Ground broke in November 2023. Construction was moving. In July 2024, the Gateway Development Commission signed a full funding grant agreement with the Federal Transit Administration locking in $6.88 billion in federal dollars.
Then the second Trump administration moved to freeze it.
In October 2025, Office of Management and Budget Director Russell Vought withheld a combined $18 billion earmarked for the Hudson Tunnel Project and the Second Avenue Subway Phase 2 project. Vought cited diversity, equity and inclusion practices in contracts, calling them unconstitutional. President Trump declared the tunnel project dead. Contractors kept work going by securing a line of credit, but that arrangement had limits.
By February 2026, the situation broke into open legal conflict. The attorneys general of New York and New Jersey filed suit against the federal government on February 3, arguing the funding suspension was unlawful. Two days later, the suspension forced a full construction halt. A thousand workers were sent home. At that point, $2 billion had already been spent on the project.
The legal fight moved quickly. On February 6, U.S. District Court Judge Jeannette A. Vargas ordered the federal government to resume reimbursement payments. The federal government filed a notice of appeal on February 8. Four days after that, the U.S. Court of Appeals declined to overturn Judge Vargas’s ruling. On February 13, the Gateway Development Commission confirmed it had received a first disbursement of $30 million from the federal government and expected payments to continue.
The stakes go beyond construction schedules. The two existing North River Tunnels, built more than a century ago and still damaged from Sandy, carry roughly 200,000 Amtrak and NJ Transit passengers daily. Engineers have long warned that losing even one tunnel to an unplanned outage would cripple commuter rail service across the region. The new tunnels are designed to allow the existing tubes to be taken offline for the first time for full rehabilitation.
New Jersey’s economy runs, in part, on the ability of workers to move between the state and New York City. Logistics, healthcare, pharma, finance. All of it depends on rail capacity that the current infrastructure can barely support. Delays on this project are not abstract. They translate into deferred maintenance on aging tubes that could fail, and into a regional economy that cannot grow its transit capacity.
As of mid-March 2026, construction has resumed. Whether federal funding remains stable through the rest of the project is a question the courts, not engineers, are still answering.
