Abstract
A highway crash attenuation system having W-beam rail elements attached to a plurality of vertical posts. An impact terminal with a feeder chute guides one or more of the W-beam rail elements through the impact terminal. The feeder chute has an impact shield extending along a traffic-facing side of the chute from an upstream-most end to a downstream-most end of the chute closing the traffic-facing side of the chute. The system also has an anchor cable release mechanism for releasing the cable downstream of the first vertical post and an improved first breakaway post.
