Abstract
A precast concrete bridge and headwall assembly includes a precast concrete bridge unit including a top wall connecting opposite side walls, and a precast concrete headwall having a bottom surface engaged on the top wall of the bridge unit and a series of earth anchors at laterally spaced intervals between the side walls. The earth anchors include a body member extending outward from the headwall to the top wall, and 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.

A method of producing a precast concrete bridge and headwall assembly, comprising the steps of:
- 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 casting 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.
