Gateway Development Commission press release reads:

NEW YORK – Senate Majority Leader Charles Schumer, U.S. Department of Transportation Secretary Pete Buttigieg, New York Governor Kathy Hochul, New Jersey Governor Phil Murphy, Senator Kirsten Gillibrand, Senior Advisor to the President and White House Infrastructure Coordinator Mitch Landrieu, and other officials joined Amtrak and Hudson Tunnel Project Sponsor the Gateway Development Commission (GDC) in celebrating the start of construction in New York on the Hudson Tunnel Project and the final phase of the Concrete Casing project.

The Hudson Yards Concrete Casing is an essential rail right-of-way preservation project that will
clear the way for the Hudson Tunnel Project’s full construction. The first two sections are
complete and run under the block bordered by 10th and 11th Avenues and 30th and 33rd Streets.
Section 3 extends the casing on a diagonal alignment from the western edge of 11th Avenue to
30th Street, where it will connect with the new Hudson River Tunnel, providing access for trains
that will use the new Hudson Tunnel into New York Penn Station. This portion of the project is
expected to be complete in Summer 2026.

In January 2023, President Biden announced that the Hudson Yards Concrete Casing – Section 3
project would receive $292 million through the U.S. Department of Transportation’s Mega Grant
Program, which was created under the Infrastructure Investment and Jobs Act, also known as the
Bipartisan Infrastructure Law.

Today’s announcement coincides with the two-year anniversary of the Bipartisan Infrastructure
Law, the Biden Administration’s landmark legislation that represents the largest ever federal
investment in public transportation.
