AEA completed the final design services for the Route 440 Ramp J over Route 35 Ramp G Bridge Deck Replacement and Miscellaneous Repairs project as prime consultant. The major items of work were accomplished includes complete replacement of the bridge deck including 3’-6” high F-shape modified bridge parapets and deck joints; Deck slab and overhang design using AASHTO LRFD Specifications; performed seismic analysis and retrofits design of the bridge; and reconstruction of abutment headers/corbels and backwalls to accommodate new deck joints and new bridge approach slabs; Miscellaneous repairs to the concrete substructures; Replacement of  substandard guide rails attached to bridge parapets; and Reconstruction of concrete curbs, milling and paving of entire ramp roadway.

In addition, AEA prepared detour routes for local traffic within Perth Amboy, as well as express traffic from the Outerbridge Crossing, and prepared temporary traffic signal timing directives at Route 35 and Waltrous Avenue for the closure of the Route 440 Ramp J over Route 35 Ramp G. The temporary traffic signal design considered modified roadway geometry, longer cycle lengths, and additional signing during construction. AEA estimated diverted traffic volumes using the express traffic detour, and prepared temporary traffic signal designs for two unsignalized intersections along New Brunswick Avenue to accommodate detoured traffic. After a decision was made to use flaggers in lieu of temporary traffic signals, determined the appropriate hours the flaggers would be required and estimated queue lengths on the exit ramp utilizing Highway Capacity Manual and HCS/SYNCHRO software. The project submissions were made in accordance with NJDOT Capital Project Delivery Process.
