ABSTRACT:
A bracket for mounting a roadway guardrail to a post adjacent a roadway involves a generally rectangular backing member having an inwardly-extending flange extending along each of the upper and lower edges thereof. The bracket can be interposed between, preferably, a W-shaped guardrail and the post with the upper and lower edges of the guardrail being located adjacent the upper and lower flanges of the bracket respectively. The normal guardrail-mounting bolt will extend through the guardrail, a central aperture in the bracket, and the mounting post for clamping the guardrail end bracket to the post. Upon the impact, particularly sliding impact from a snowplow or the like, the upper and lower edges of the guardrail will contact the flanges and further deformation thereof will be resisted by the flanges. Thus the guardrail which would otherwise be detrimentally deformed by minor impacts will now retain its shock-absorbing capabilities, such detrimental having been resisted by the back of the invention.
