PRECAST CONCRETE BRIDGE UNIT AND HEADWALL ASSEMBLY AND METHOD OF PRODUCTION
A method of producing a precast concrete bridge and headwall assembly including casting a reinforced concrete bridge unit having a top wall connecting opposite side walls; positioning the bridge unit with a first side supported by a horizontal casting surface, wherein the top wall is positioned adjacent a framing unit for the headwall; forming a precast concrete headwall on the casting surface adjacent the top wall with a series of earth anchors at laterally spaced intervals along the top wall between the side walls, each earth anchor formed with: a) a body member extending outward from the headwall to the top wall; and b) a foot member extending laterally outward from the body member engaged on the top wall and including an upper surface generally parallel to the top wall; and removing the headwall and earth anchors as a unit from the bridge unit.
