ABSTRACT:
A traffic barrier section with a centrally-located, built-in carrier is disclosed. The carrier includes a fluid-operated ram which is connected to an axle carrying wheels located below the ram. Then the wheels are in a retracted position, the barrier section rests on the ground and when the wheels are extended, the barrier section is supported fully on the wheels. In that position, a plurality of the barrier sections which are pivotally connected in end-to-end relationship can be moved from one construction site to another as needs change. Each axle and the wheels can be turned to a position other than perpendicular to the longitudinal extent of the barrier section so that some of the barrier sections can be moved transversely to place them in other than a straight line position.
