Havengore Bridge is another area which can be closed when activities are taking place on the range. The outer sea area around the bridge is only open when the range is not in use and several hours each side of high tide. All other areas off limits to the public along the Shoebury coastline are clearly signposted and warn of the dangers of trespassing, as well as hazards such as unidentified objects. What should I do if I find an unidentified object? It is possible that members of the public will find objects in areas they are allowed to go.
