The Height restriction barrier or traffic gantry are mainly used for gate-shaped frames at the entrances of bridges, culverts and tunnels, parking lot or commerical area. They are generally welded steel structures and play the role of protecting bridges, culverts and tunnels. There are signs or LED light on them with the height limit in meters to remind vehicles. The height barrier also can add swing structure to use for paking lot, to allow vehicle access.
