New County Road Bridges

Seacaucus, NJ

The last project in the $450 million infrastructure upgrade, called the Secaucus Interchange and Rail Transfer Station Program (SIP), was to connect 11 rail lines in northern New Jersey to reduce passenger commute times and increase destinations.

The program included the construction of a new rail station, expansion of the rail line from two to four tracks, and development of an $84 million interchange on the New Jersey Turnpike expressway (I-95). This portion of the project entailed constructing bridges and expanding local roads in Secaucus to handle the increase in traffic.

Conti rehabilitated the New Country Road bridges (SIP 501 project). Work included a dual-span bridge built over a rail yard and a single-span bridge built over ramps leading to a busy roadway. The team coordinated daily with Norfolk Southern, Conrail, and Hudson County to develop a detour that would minimize traffic impact and support extensive truck traffic.

Conti handled utility relocations for electrical, gas, telecom, sanitary, drainage, and fiber-optic lines. The team drove steel sheeting down the center of the road and built a temporary ramp to separate live traffic from work operations. Conti also developed a wetland mitigation and enhancement plan.

The team used an innovative slip form design mix technique during the concrete bridge parapet construction process, as well as re-staging work to meet an aggressive fast tracked schedule for the project. This and other time- and money-saving techniques won Conti excellent reviews from the NJTA.

“Conti’s team approach and positive attitude were key to maintaining schedules in a highly congested area with numerous constraints.” – Assistant Chief Engineer, Construction, NJTA
