This project was a complete superstructure replacement of an existing 2-span concrete encased steel bridge carrying NJ Route 54 over US Route 322. 

Substructure work included analysis and detailing of the pier and abutments to accommodate the new superstructure including a determination of the need for lightweight fill at the abutments, seismic analysis of the pier and abutments, and modifications to the bridge seats as required to accommodate the new superstructure geometry.

Malick & Scherer, P.C. was responsible for all structural design, including the design of a 2-span simply supported prestressed voided slab beam superstructure on reconstructed substructure units. 

The superstructure consisted of adjacent 21” deep prestressed concrete voided slab beams topped with an 8” minimum concrete deck. Sidewalks were provided at each side of the bridge, along with concrete parapets and curved picket fence.
