The U.S. Army Corps of Engineers (USACE) continues working to restore or maintain the Mississippi River Ship Channel in areas on the Crossings Above New Orleans. The dustpan dredges, JADWIN and WALLACE McGEORGE and the hopper dredge BAYPORT are presently working on the Crossings Above New Orleans.
DEWATERING OF THE INNER HARBOR NAVIGATION CANAL LOCK:
The cutterhead dredge CAPTAIN FRANK completed dredging on Baptiste Collette and the USACE expects to move forward with the dewatering of the IHNC Lock as planned tomorrow morning Friday, September 4, 2020. The dewatering of the IHNC Lock is scheduled to require a full closure for 60 days. The USACE reported the shallow-draft alternate route (Baptiste Collette) is in good condition now and that channel surveys will be updated and posted online. The U.S. Coast Guard reports that all Aids to Navigation are in place and online properly marking the alternate channel route, the Marine Safety Information Bulletin with complete details is attached (UPDATED Inner Harbor Navigational Canal Lock Closure and GIWW Alternate Route).
