The Great Wall, flood protection built to protect New Orleans
Great Wall in LA09.jpg
The Inner Harbor Navigation Canal Lake Borgne Surge Barrier also called The Great Wall of Louisiana, is a nearly two-mile-long, 26-foot-high barrier built for hurricane protection to prevent the kind of flooding that ravaged New Orleans by Katrina. The wall crosses Gulf Intracoastal Waterway and Bayou Bienvenue and has three gates boats can use for passage unless a storm threatens. The project was created by the US Army Corps of Engineers.
