Hudson Tunnel Project (Gateway Program)

Builds a new Hudson River rail tunnel (opening targeted 2035) and rehabilitates the century-old existing tunnel (targeted complete 2038), doubling passenger-rail tunnel capacity between New Jersey and Manhattan. In October 2025 the federal Office of Management and Budget withheld funding for this project (along with Second Avenue Subway Phase 2), citing objections to "DEI principles"; work was briefly suspended February 2–6, 2026 before $235 million in unfrozen funds allowed full resumption on February 24, 2026.

Why This Isn't in DOB's Live Data

This is a bi-state federal/interstate commission project, not subject to standard NYC Department of Buildings permitting the way private construction is — so it doesn't and won't appear in DOB Job Application Filings or DOB Permit Issuance, the two datasets the rest of this site is built on. That's why it's tracked here by hand instead of pulled live like everything else on Constructel NYC.

Who's Building It
