Written by 
The joint venture known as THE Partnership (THEP), consisting of Parsons Brinckerhoff, AECOM, and STV, Inc., has been awarded a contract modification worth $111 million for the New Jersey Transit/Port Authority of New York & New Jersey multi-billion-dollar, 3.5-mile Trans-Hudson Express Tunnel (THE Tunnel), also known as the ARC (Access to the Region’s Core) Mass Transit Tunnel.

The project includes the construction of two new tracks in New Jersey’s Meadowlands, two new single-track tunnels under the Hudson River, and an expansion of Penn Station New York under 34th Street, including direct connections to city subways at 8th, 7th, and 6th avenues as well as Port Authority Trans Hudson (PATH) trains. Additional capacity and a connection to New Jersey Transit’s Main, Bergen County, Pascack Valley, and Port Jervis lines will allow for transfer-free service to Penn Station New York. The project also includes new train-storage facilities in Kearny, N.J.

A variety of construction methods will be employed to advance the project, including tunnel-boring machines, rock mining, sequential excavation, and cut-and-cover.
