What is a Cattle Guard?
A cattle guard is a series of parallel metal bars which is installed in a roadway over a ditch to prevent ungulates from escaping a fenced area. The parallel bars are designed to be wide enough so that hooves and legs will fall through, while cars can drive over them safely, although they do need to slow down. Most hoofed animals are smart enough to recognize the potential hazard of a cattle guard, and they will avoid them: in some cases, animals will even avoid lines painted on a busy road to resemble a cattle guard. Cattle guards are in use all over the world as a practical alternative to gates, which must be opened and closed every time someone wants to pass through.
