NEW YORK, NY — The Gateway Development Commission (GDC) announces that the Hudson Yards Concrete Casing - Section 3 (HYCC-3) Project is more than 50 percent complete and is on track to be finished in 2026. The project reached this milestone on schedule and on budget.
The Hudson Tunnel Project (HTP) is the nation’s most urgent mass transit infrastructure project, which will provide train service into, out of, and through New York, and end the immediate threat posed by the 115-year-old tunnel between New Jersey and New York.
The HYCC-3 Project is building the final link that will enable the new tunnel to connect to New York Penn Station. The other two sections of the concrete casing were completed in 2018. This section is approximately 500 feet long, 60 feet wide, and 60 feet deep. Its structure will consist of heavily reinforced concrete ranging from 3.5 to 10 feet thick, with a waterproof membrane covering its perimeter.
Construction of the HYCC-3 Project is supporting 4,820 jobs and $986 million in economic output. In total, construction of the HTP is projected to support 95,000 jobs and drive $19.6 billion in economic activity.
Amtrak is the supporting or executing partner and construction manager on the HYCC-3 Project, working on behalf of GDC.

“We talk about the HTP as a single megaproject, but when you think about the scope and complexity of each construction package, it is more like 10 megaprojects rolled into one," GDC CEO Tom Prendergast said. "Reaching the halfway point on the HYCC-3 Project on scope, schedule, and budget is an amazing accomplishment that speaks to the entire GDC team’s expertise and dedication, but our work is just beginning."
Five of the ten construction projects that make up the HTP are currently in progress, and GDC anticipates awarding contracts for two more projects in 2026. Aside from the HYCC-3 Project, the other ongoing projects include:
- The Tonnelle Ave Bridge and Utility Relocation Project will enable the Tunnel Boring Machines (TBMs) to launch by building a new roadway bridge supporting the highway, creating access to the entry point for digging. This project is more than three-quarters finished and is on track to be completed by the end of 2025.
- The Hudson River Ground Stabilization Project involves mixing concrete into the silt that makes up the shallow riverbed on the Manhattan side of the Hudson River to create a block of reinforced earth that is strong enough for TBMs to pass through. Geophysical surveying of the entire area set to be stabilized has been completed, and concrete mixing is in progress.
- The Palisades Tunnel Project is the first tunnel boring project of the HTP. Early work, including installing monitoring equipment, geotechnical borings, and clearing the area where the TBMs will launch, is in progress and the TBMs are in production. Tunnel boring is expected to begin in 2026.
- The Manhattan Tunnel Project will build a section of the new tunnel connecting to the Hudson Yards Concrete Casing and an access shaft at 12th Avenue that will be used to remove the TBMs that build the portion of the tunnel under the Hudson River. GDC awarded the contract for this project in February, and early work began in April.
