The Great Wall Of Louisiana

The Great Wall Of Louisiana
The IHNC Lake Borgne Surge Barrier also called the Great Wall of Louisiana is a storm surge barrier constructed near the confluence of and across the Gulf Intracoastal Waterway and the Mississippi River Gulf Outlet near New Orleans. The barrier runs generally north-south from a point just east of Michoud Canal on the north bank of the GIWW and just south of the existing Bayou Bienvenue flood control structure. Navigation gates where the barrier crosses the GIWW and Bayou Bienvenue reduce the risk of storm surge coming from Lake Borgne and/or the Gulf of Mexico. Another navigation gate (Seabrook Floodgate) has been constructed in the Seabrook vicinity where the IHNC meets Lake Pontchartrain to block a storm surge from entering the IHNC from the Lake.
