cattle guard

Encyclopedia Article


Also know as a cattle grid, this metal grate is used to deter livestock from crossing a road or train tracks. The guard extends across a depression in the road, secured on both sides. The spaces between the bars are small enough to allow cars and other vehicles to pass over, but large enough for an animals' foot to fall through, making animals reluctant to cross, ideally preventing them from crossing the road.
