- 22 - Abstract A light weight, ballasted temporary highway median barrier of the type wherein a plurality of barrier units are positioned in an end-to-end relationship to provide a substantially continuous barrier for temporarily dividing a roadway into two lanes of traffic which are intended to move in opposite directions and to inhibit head-on and side-swipe collisions between vehicles moving in opposite directions in those respective lanes is disclosed. According to a first embodiment, a hollow shell which accommodates a ballast bag for receiving and retaining a liquid ballast is connectable to identical units to form a substantially continuous temporary highway median barrier. In a second embodiment, a fully enclosed shell having end walls and a bottom wall likewise accommodates liquid ballast. Each type of unit includes accessible drain orifices for draining liquid ballast from the respective units. The units are preferably constructed to be approximately twice as wide as the standard pre-cast temporary concrete barrier of the same type so that the barriers provide substantially the same mass as a concrete barrier to resist an impact from a colliding vehicle. The advantage of the barriers is that they are light in weight, easily handled and the first embodiment provides a stackable unit for efficient storage and transport.
