Role description:

Arcadis is seeking a highly skilled and motivated Project Engineer (Civil/Enviromental) to support one of the most iconic and consequential infrastructure initiatives in the United States — the Gateway Hudson Tunnel Project (HTP).

The project encompasses the construction of a new, two-track rail tunnel beneath the Hudson River, along with the full rehabilitation of the existing 113-year-old North River Tunnel. This vital infrastructure supports more than 200,000 daily passengers via Amtrak and NJ TRANSIT and serves as a backbone for economic activity and connectivity between New York and New Jersey.
