Throughout the construction period and while workers are present, all mariners are requested to pass with extreme caution at their slowest safe speed to minimize wake, ensuring the safety of the contractors working on the Huey P. Long Bridge.

On closure days, a temporary reporting point for all down-bound vessels has been established at Guy Mallory Light #114, MM 112.9, LDB. Vessels operating in close proximity to the Huey P. Long Bridge sector (Guy Mallory Lt. MM 112.9 to Cargill Grain Elev. Westwego MM 103.1) are required to monitor Channel 12 VHF-FM for updates and up to the minute instructions on vessel movement plans after the reopening of the waterway.

During scheduled closures, a Safety Zone will be in effect from the start of the closure until the marine traffic backlog has been cleared after the reopening of the waterway. The Vessel Traffic Service (VTS) will manage vessel movement to clear up traffic that has stopped or slowed to accommodate the closure. All vessels will be required to contact "Vessel Traffic" on Channel 12 VHF-FM for permission to transit through the construction site during the post closure time period of the Safety Zone. The Safety Zone will end after the backlog of vessels has been cleared and marine traffic has been returned to a normal flow by the VTS.
