The New Jersey Turnpike Authority initiated the Secaucus Interchange Program in concert with planning for Allied Junction to help establish a new gateway to New Jersey’s “Gold Coast,” Bergen and Hudson Counties located just west of New York City. The goal of the program was to use transportation improvements as a conduit for job promotion, construction, sustained commerce and the strategic renaissance of Hudson County by linking Frank R. Lautenberg Rail Station and the New Jersey Turnpike. The Secaucus Interchange Program was divided into five project design sections with multiple construction contracts. The Louis Berger Group was the lead consultant for two contracts, sections 2 and 3. LBG prepared final design and contract documents for construction of a 3,100-ft, high-level curved ramp structure spanning over wetlands and the New Jersey Transit main Line. The design challenges included construction in the eco-sensitive meadowlands adjacent to rail traffic, utilities and other facilities. LBG led the design team that developed innovative concepts required to solve constructability issues and address temporary and permanent impacts to the wetlands. Our engineers developed a complex horizontal and vertical alignment that passed over NJT tracks and transmission lines and also provided for future connections to Tonnelle Avenue and Bergen Arches. LBG completed the design documents within a fast-track schedule of 11 months.
