C :/RPonb/DCCSEH/4655287_.DOC-4/(V2012 - 40 A traffic barrier system for positioning at a water crossing portion of a road, the system including an upstream support for positioning on an upstream side of the road, a downstream support for positioning on a downstream side of the road, and a buoyant barrier connected to the upstream support, the barrier being provided in a storage position alongside the road for allowing traffic to pass along the road, the barrier being configured so that a flow of water across the road causes the barrier to float on the water from the storage position and move to a deployed position in which the barrier engages with the downstream support so that the barrier spans between the supports to thereby prevent traffic from passing along the road.
