A single anchor terminal is provided for a roadside wire rope barrier. The single anchor terminal includes a release post, a brace, and an anchor base. The brace supports the release post in an upright position and extends from the release post to the anchor base. The brace has a first portion attached to the release post and a second portion coupled to the first portion with a release component. The anchor base includes a main post that supports the release post and a brace anchor that is coupled to the main post.

Single anchor terminal

A guardrail terminal end system for use at the upstream end of a W-beam guardrail mounted along the side of a roadway. The system includes a flat plate rail which extends horizontally along and is flared away from the roadway in a substantially straight linear direction and is supported by a plurality of horizontally spaced vertical break away posts. A vertical energy absorbing cylinder is supported by a vertical break away post which is located generally along the center line of the cylinder. The rail is operatively associated with the cylinder to attenuate the force of a vehicle impacting the cylinder. A transition shoe has a flat section which connects to the downstream end of the flat rail and a W-beam section which is adapted to connect to the standard W-beam guardrail. The cylinder distributes the load of an impacting vehicle equally on its support post to rapidly shear the post and cause bending or buckling of the flat rail which has low column strength in comparison to a W-beam rail. The flat rail bends or buckles on itself at each support post to create a failure mode at each post and thus absorb more energy from the impacting vehicle.
