Abstract

A cable guardrail release system includes a first number of anchor posts installed adjacent a roadway.
Each of the first number of anchor posts secures an end of a respective cable. Each anchor post is operable to release the respective cable secured by the anchor post upon a vehicle impact to the anchor post. The system may include a length of need section that includes a plurality of intermediate support posts each configured to support each of the respective cables. The length of need section may include portions of each of the respective cables running in between the plurality of intermediate support posts. Each anchor post may be configured to resist release of the respective cable secured by the anchor post upon a vehicle impact to the length of need section generally at an angle to the flow of traffic on the roadway.
