Cable Barrier System

A cable barrier system, sometimes referred to as guard cable or wire rope safety barrier, is a type of roadside or median safety traffic barrier/guard rail. It consists of steel wire ropes mounted on posts. As is the case with any roadside barrier, its primary purpose is to prevent a vehicle from leaving the traveled way and striking a fixed object or terrain feature that is less forgiving than itself. Also similar to most roadside barriers, cable barriers function by capturing and/or redirecting the errant vehicle.

Because these barriers are relatively inexpensive, as opposed to concrete step barriers to install and maintain, and are very effective at capturing vehicles, their use is becoming increasingly prevalent worldwide.
