In one aspect, the present invention teaches a safety barrier including a plurality of cable posts spaced from each other and disposed adjacent to a roadway. At least two cables are releasably engaged with and supported by the cable posts. The cable posts and the two cables cooperate with each other to prevent a vehicle from leaving the roadway. A plurality of guardrail posts are spaced from each other and disposed adjacent to the roadway longitudinally spaced from the plurality of cable post. A guardrail beam is fixedly coupled to the plurality of guardrail posts and including slots. The two cables extend from the cable posts through respective slots formed in the guardrail beam permitting each cable to engage a respective cable anchor bracket securely fastened to a portion of the guardrail beam.
