One of the most urgent rail infrastructure programs in the US, the Hudson Tunnel Project (HTP), is a transformational effort to build a new two-tube rail tunnel under the Hudson River between New York City and New Jersey. It also includes rehabilitating the existing tunnel and improving passenger rail tracks between the two states.

MPA Delivery Partners, a joint venture of Mace, Parsons Corporation, and Arcadis, is supporting the Gateway Development Commission in delivering the project. In 2025, the joint venture received a 4.5-year contract extension. MPA was initially selected as delivery partner in 2024.

Construction of the HTP is expected to create over 95,000 jobs across the US and generate over $19 billion in economic activity. In New York, New Jersey, and across the country, the project is driving demand for domestic suppliers of steel, aggregates, rail, track, and ventilation systems. The new Gateway Tunnel is scheduled for completion in 2035, with rehabilitation of the existing tunnel by 2038.

This is a once-in-a-generation project and a true collaboration between public and private sectors. It will serve as a model for delivering future mega-infrastructure projects around the world.
