Project Type: Structural and Seismic Design

Route 1&9 (Pulaski Skyway)

Newark and Kearny, NJ

The Skyway is a 3.5-mile elevated structure composed of a series of bridges that carries Route 1 & 9 over the Hackensack and Passaic rivers, the New Jersey Turnpike, several railroads and industrial facilities. This vital regional Transportation link handles over 70,000 vpd.  Arora completed a prioritization report for major maintenance and rehabilitation following six consecutive cycles of inspection. Arora, as a prime consultant for Contract 6, is providing the structural rehabilitation and seismic retrofit of the spans over the Hackensack River (spans 61 to 79). This 18 span section is 5,827’ long. This independent rehabilitation project will provide an additional 75-year service life to the structure.  Work entails seismic retrofit, replacement of rocker bents, rehab/replacement of steel truss members, increasing foundation capacity with new drilled shafts, and pier shell construction to replace existing piers. Arora developed 3D finite element model using CSiBridge for general structural and seismic analysis and Midas for soil-structure interaction for a multi-mode spectral analysis for a 1,000-year return period earthquake defined by a site-specific response spectrum. Additional tasks include highway design, construction staging and MPT plans, stormwater management and US Coast Guard approval. Arora is also responsible for utility coordination and ITS design for the entire Pulaski program.  Piers 76 and 77 have been constructed under Contract 5 and Contract 6 cost is anticipated to exceed $300 million. Previously as a subconsultant, under independent agreement for Contracts 3&4, Arora was responsible for accelerated inspection and contract plan preparation for repairs to the bridge deck, curb and historic balustrade, hangers, piers and pier caps, deck joints and bearings repair/replacement, staging and MPT plans. The responsible cost of the construction contract was over $35 million. All work was performed within the allocated budgets and schedule.
