ABSTRACT:
A speed bump for use in connection with highways located in climates where snow plow is used to clear the highways includes a raised mass fabricated from highway construction material. The raised mass has a crown, a base where the raised mass meets a surface of the highway, and a slope of the raised mass between the crown and the base. The slope presents a profile in the area of the slope at which a snow plow is likely to encounter the speed bump such that the snow plow is lifted smoothly over the speed bump.
