The Hudson Yards Concrete Casing – Section 3 Project will provide the vital link that connects the new Hudson River Tunnel to New York Penn Station.

The Hudson Yards Concrete Casing – Section 3 (HYCC-3) Project is an essential rail right-of-way (ROW) preservation project on the west side of Manhattan that will enable the new Hudson River Tunnel to connect to New York Penn Station.

This project involves extending the existing concrete casing on a diagonal alignment from 11th Avenue to 30th Street, where it will link up with the new tunnel.

HYCC-3 will be approximately 500 feet long, 60 feet wide, and 60 feet high. Its structure will consist of heavily reinforced concrete ranging from 3.5 to 10 feet thick to support future loading from the overbuild platform. A waterproofing membrane will cover its perimeter.

Background

The design and construction of the concrete casing beneath Hudson Yards has been in progress since 2012.

Sections 1 and 2 of the concrete casing were built underground in the block bordered by 10th and 11th Avenues and 30th and 33rd Streets. Construction of the first 800-foot section (between 10th and 11th Avenues) began in August 2013. The second section extended the project west another 105 feet under the 11th Avenue viaduct in Manhattan. Both sections were completed in 2018.

HYCC-3 is the final segment that will enable the new Hudson River Tunnel to connect into New York Penn Station.

Current Activities & Next Steps

Construction of HYCC-3 launched in November 2023, marking the start of work on the Hudson Tunnel Project in New York. Construction is expected to conclude in 2026.

This project is funded by a $292 million grant through the U.S. Department of Transportation’s Mega Grant Program, which was created under the Bipartisan Infrastructure Law.
