Overpass bridge replaced in 57 hours

According to a report by the Accelerated Bridge Construction University Transportation Center, in Florida, a bridge was replaced in just 57 hours. The bridge is the Route 30 bridge over Bessemer Avenue in Pennsylvania.

The project used accelerated bridge construction to speed up the process. The bridge was constructed with precast concrete abutment caps, modular deck beams, and precast concrete approach slabs. The six modular deck beams consist of two steel I-girders, which were connected with ultra-high performance concrete deck joints.
