A guardrail system includes a plurality of posts spaced apart along a longitudinal direction and a plurality of rail sections extending between and coupled to the spaced apart posts. Each of the rail sections includes an uppermost surface. A cable extends along the longitudinal direction and is coupled to the rail sections and/or posts. The cable is vertically spaced above the uppermost surface of the rail sections. A guardrail retrofit kit includes a front anchor bracket, a rear anchor bracket, an intermediate bracket and a cable having end portions adapted to be coupled to the front and rear anchor brackets. The intermediate bracket is configured to releasably capture the cable. Methods of retrofitting a guardrail system and arresting a vehicle impacting a guardrail system are also provided. |
