The New Jersey Turnpike Authority undertook a major program to replace and reconstruct bridge and roadway surfaces in order to maintain this vital traffic route, phasing work to minimize the disruptions to commuters.
Conti reconstructed a high performance structural concrete deck bridge roadway slab over the Hackensack River, spanning over a mile along the eastern spur of the mainline New Jersey Turnpike between exits 15E and 15X. Conti performed seismic retrofits and structural steel repairs, including the removal of existing paint from the structural steel members and applying a new four-coat paint system. The project team removed and reconstructed deck joints, replaced median barriers, modified the wingwalls, repaired the substructure, improved lighting, reconstructed the shoulder structures, resurfaced the deck, and rehabilitated the access walkway.
Conti worked with NJTA and the designer to restage the project by using a half-section barrier system that enabled more flexible staging. The Turnpike Authority was open to this alternative provided the proposed barriers met FHWA specifications. Conti consulted with industry professionals and conducted a crash test to prove the barrier system would safely work and meet the specifications. This resulted in reducing the project from five to four stages and an overall schedule reduction of 7 months. This project was awarded the 52nd Annual NJ Grand Concrete Award by NJ Concrete.
Conti staged the project in this heavily congested traffic artery to reduce the schedule by 7 months.

SCDOT needed a new interchange along I-26 to provide direct access to the newly-built Volvo Manufacturing Facility providing 2,000 jobs to local workers.
One of the busiest and most congested interchanges in New Jersey, the intersection of I-295, I-76 and Route 42 in Camden County handles daily traffic volumes of over 250,000 vehicles and has one of the highest accident rates in the state.
