ABSTRACT:
An impact barrier and restraint is provided for use on a longitudinally extending roadway. There are several barrier mechanisms, each including a base or diaphragm extending transversely of the roadway and related to the roadway by releasable anchors. In one version the diaphragm includes overlapping, transversely extending plates arranged to move transversely of the base. There are lateral buffer beams diverging and overlapping and secured to the diaphragms and to each other for telescoping movement. Between the diaphragms there are energy absorbing cells supported on the base and subject to disintegration upon impact of a vehicle or the like against the impact barrier, whether head-on or from the sides.
