The Coast Guard is establishing a temporary safety zone for all navigable waters from mile marker 45 to mile marker 47 of the Port Allen Route, Iberville, LA. The safety zone is needed to protect Grosse Tete bridge repairs and ferry operations for crossing school students during morning and afternoon commutes as a result of the Grosse Tete bridge closure. Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port, Sector New Orleans.
