Abstract: A reusable composite bridge structure permits composite strength action of steel girders and concrete deck panels in a bridge structure that is removable and reusable. The bridge comprises precast concrete deck panels, each of the panels having a plurality of holes therein extending through the panels to match stud group locations on top flanges of steel girders, the holes having smooth inside surfaces through the panels, a plurality of shear studs at each of the stud group locations extending up from the top flanges, the shear studs having removable connections to the top flanges, and concrete grout filling the holes of the deck panels and between adjacent deck panels to provide a substantially flush deck surface, the concrete grout joining the shear studs and the panels to provide composite strength action between the deck panels and the bridge girders.
