Purpose

This $16 billion project involves building a new two-track rail tunnel under the Hudson River and rehabilitating the existing 114-year-old tunnel. It is critical for the Northeast Corridor, as it doubles capacity for Amtrak and NJ Transit trains, ensuring the reliability of the busiest rail link in the United States.
