The Coast Guard is establishing a temporary safety zone for navigable waters within a 1000-foot radius of the Gibbstown Bridge. The safety zone is needed to protect personnel, vessels, and the marine environment from potential hazards created by pulling transmission wires over the waterway. Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port Marine Safety Unit Port Arthur.
