Corbin Street

Port Authority engaged SJH to prepare Final Design and Contract Documents (III), as well as performing Post Award Services (Stage IV) for the Corbin Street Ramp rehabilitation including study report for (8) elastomeric bearing at one Pier (Pier 12). Located in Port Newark, the Corbin Street Ramp over Conrail (Structure Number 38000033) is an 865 ft. long, 16-span partially curved viaduct carrying two lanes of one way (southbound) vehicular traffic from Port Street to Corbin Street. The curb-to-curb width varies between 29’-0” to 25‘-0”. There is Jersey shaped barrier along the east fascia between Spans 12 to 16, and vertical faced parapet/metal railing with safety walk between Spans 1 to 11 on the east side and full length on the west side. The superstructure consists of steel multi girder with non-composite reinforced concrete deck. The substructure consists of reinforced concrete pier bents and full height abutments.

The design effort included visiting the site for inspection and necessary measurements, coordination with Port Authority Traffic Operations for lane closure hours and lane shifts, and coordination with utility companies for temporary tower locations. Nineteen (19) design drawings and a bearing study report were developed, along with specifications and engineer’s estimate. Our design addressed repair work for the repair of large spalls, cracks, hollow/delaminated areas at piers, columns, cap beams, pedestals, and deck slab. Temporary towers were installed during the construction to support the bridge. The bearing study report included repair alternatives and order of magnitude cost estimates for (8) elastomeric bearings that exhibited up to 3/8” transverse oscillation under live loads. SJH also provided construction support services including review of shop drawings and responding to Request for Information (RFIs) by the contractor.
