A prefabricated bridge system was designed to minimize on-site construction time. The system consists of a double-cell adjacent box beam superstructure supported on precast posttensioned abutment units on cast-in-place footings. The design concept was implemented in a demonstration bridge replacement project, a single-span bridge crossing a creek in southwestern Pennsylvania. The construction project demonstrated the feasibility of the design concept as a means to reduce construction time by eliminating cast-in-place concrete for abutment walls.
