Route 7, Hackensack River (Wittpenn) Bridge, Contract 1 – River Piers & Pier Protection System (DP#11111) NJDOT

Project Overview :

The Wittpenn Bridge, in service since 1930, is undergoing a complete reconstruction. Contract 1 involved the river piers & pier protection system, which includes the construction of drilled shafts, concrete piers, and pier protection for the river portion of the new bridge.

New Jersey Route 7, a major connector between the Holland Tunnel and the NJ Turnpike, carries over 50,000 vehicles per day across the Wittpenn Bridge and is an important link for both commuters and cargo transport across Hudson County.

Working closely with Conti, Garden State provided survey control, construction layout and monitoring services for the construction of a concrete precast cofferdam system as well as setting of large steel encased concrete piles to support the new bridge piers and abutments. The projected cost of the project was approximately $500 million.
