USACE will close and dewater the IHNC Lock for 60 days starting on September 4, 2020 to investigate and repair lock wall leaks.

  • To allow mariners to continue to travel to and from the East Canal, the Chandeleur Sound – GIWW Alternate Route will again be activated.
  • The route (west to east) generally follows the Mississippi River to Bayou Baptiste Collette then northward in the Chandeleur Sound to the Gulfport Ship Channel and the GIWW East.
