ABSTRACT:
A crash cushion having a plurality of beams extending substantially parallel to one another. One end of the crash cushion may be slidably coupled with one end of a traffic barrier. Another end of the crash cushion faces oncoming traffic. A plurality of support posts are coupled to and support the plurality of beams. Forceful impact of a vehicle with the end of the crash cushion facing oncoming traffic results in energy absorption during telescoping of the beams relative to the traffic barrier. A method of manufacturing crash cushions and other energy absorbing devices is provided.
