Abstract
A prefabricated, modular bridge is provided that can be assembled to construct bridges of various lengths, widths and skew angles relative to the orientation of foundation elements. The modular bridge includes longitudinal frame members, and a roadway surface made of roadway deck panels and transverse hubs. The transverse hubs define transverse ledges to support ends of the roadway deck panels. The transverse hubs have attached hub attachment clamps that move transversely relative to the transverse hubs to selectively disengage or engage the top flanges of the longitudinal frame members. An assembly for splicing the longitudinal frame members is provided, including an anchor bolt extending between bearing support members attached to the longitudinal frame members. An external reinforcing assembly for the modular bridge is also provided. The external reinforcing assembly includes longitudinal tendons, anchor blocks, and spacers and hangers for deviating the tendons from the bottom flange of the frame members.
