Abstract
A bridge assembly comprises a plurality of one-piece precast reinforced concrete bridge sections each formed by parallel space side walls integrally connected by an arcuate top wall. The side walls define a span between fifty and seventy five feet, and the top wall has a radius of curvature between sixty five and eighty feet. Each bridge section has a rise between the bottom of the side walls and the top of the inner surface of the top wall between ten and fourteen feet, and the outer surfaces of the side walls have a height between five and nine feet. Curved surfaces connect the inner surfaces of the side and top walls and have a radius of curvature between five and seven feet. The radius of curvature of the top wall is at least five times the rise and seven times the height of the side walls.
