Hudson Tunnel Project: Official 2026 Status, Route Map & Cost
The Hudson Tunnel Project is a major passenger rail infrastructure initiative constructing a new two-track river crossing and rehabilitating the existing North River Tunnel to improve reliability along the Northeast Corridor between North Bergen, New Jersey, and New York Penn Station; this guide details the complete hudson tunnel project. Spanning approximately 4.5 mi, the alignment establishes a crucial redundant right-of-way under the Hudson River, connecting New Jersey suburban corridors directly to Manhattan. Managed by the GDC in coordination with Amtrak, NJ Transit, and the FTA, the project is backed by a $16.1B funding model driven primarily by IIJA federal grants and regional matching funds. Following extensive environmental review and official plans, early civil works and tunnel boring preparation are moving forward toward an estimated completion date of 2035 for the new tubes. By expanding capacity on North America's busiest transit corridor, the project safeguards long-term regional mobility, resilience, and economic growth.
Project information is compiled from official agency documents, federal records, environmental reviews, and verified public announcements.
