PRECAST CONCRETE BRIDGE UNIT AND HEADWALL ASSEMBLY AND METHOD OF PRODUCTION
A method of producing a precast concrete bridge and headwall assembly, includes the steps of casting a reinforced concrete bridge unit having a top wall connecting opposite side walls, releasably attaching a series of counterfort forms to the top wall of the bridge unit at laterally spaced intervals between the side walls, and positioning the bridge unit with a first side supported by a horizontal casting surface, wherein the top wall is positioned adjacent a casting framework and a bottom edge of the counterfort forms is located adjacent the casting framework. The method further includes precasting a concrete headwall unit onto the casting surface, precasting a series of counterfort members into the counterfort forms before the headwall has completely hardened, removing the series of counterfort forms from the top wall of the bridge unit; and removing the headwall and counterfort members as a unit from the bridge unit.
