Please accept this reminder that the 48-hour period of one-way transits from Mile 2 Above Head of Passes (AHP) to the Head of Passes (Mile 0) will commence at 0600 hours tomorrow morning (Sunday, November 17, 2024). This period of one-way transits should be seamless as pilots often implement one-way transits when dredges are working from Venice to the Southwest Pass jetties. 

The U.S. Army Corps of Engineers (USACE) recently awarded a cutterhead dredge rental contract to Weeks Marine to remove 4 million cubic yards (mcy) in the base of the contract with options to add up to another 4 mcy of dredged material to be removed from the Hopper Dredge Disposal Area (HDDA). Weeks Marine will utilize the cutterhead dredge R.S. WEEKS to begin this dredge contract with submerged dredge pipeline installation operations scheduled to start on Sunday, November 17, 2024. The expected schedule for the submerged pipeline installation and dredging is detailed below. The pipeline will cross the Ship Channel from east to west between Mile 1.4 Above Head of Passes (AHP) and Mile 1.2 AHP. The material will be beneficially utilized in the West Bay Receiving Area and will bring the total to over 14,000 acres created since 2009, the largest wetlands restoration project in the world. 

The Marine Safety Information Bulletin as issued by the U.S. Coast Guard is attached and was developed with the input of industry and pilots’ associations.
