An anchorless crash cushion apparatus comprises a number of crash cushion elements and a number of hinge plate assemblies. The crash cushion elements are configured to be connected end-to-end. Each hinge plate assembly comprises a forward structure, a rearward structure, and a wedge incline. The forward structure supports the front end of one of the crash cushion elements. The rearward structure supports the rear end of the crash cushion element. The wedge incline extends diagonally upward toward the forward structure and is configured to drive a subsequent one of the crash cushion elements upward when the forward structure is driven toward the subsequent one of the crash cushion elements.

Hinge plate with wedge

A crash cushion includes a number of spaced-apart supports or bulkheads; energy absorbing modules positioned between the supports; overlapping side panels that interconnect the supports and envelop the energy absorbing modules; front and rear fixed anchors; and reinforcing cables extending between the anchors. The cables extend through cable guides formed in the supports so as to stabilize the supports and facilitate controlled collapse of the supports during vehicle impacts.
