Abstract: A traffic barrier section is disclosed herein. The traffic barrier section includes a prefabricated or pre-cast concrete barrier wall section and a poured in-place (i.e., in-situ) moment slab footing. As constructed, the traffic barrier section is suitable for constructing a continuous protective barrier for a roadway. In that regard, a plurality of traffic barrier sections are placed side-by-side in close proximity and supported on a retaining wall to form a continuous protective barrier along the edge of the roadway. In use, the erected continuous protective barrier restrains a moving vehicle on the elevated roadway from traveling over the edge of the retaining wall.

Abstract: Embodiments of retaining wall systems suitable for use as a traffic barrier for roadways include a prefabricated concrete retaining wall section and a pour-in-place footing. Another system includes a pre-cast retaining wall section and a pre-cast footing. In use, a plurality of retaining wall sections may be placed side-by-side in close proximity to one another to allow for a continuous retaining wall to be constructed.
