Lake Pontchartrain Causeway consists of two parallel bridges that are the world’s longest bridge in total length. Total length of the two bridges is 23.87 miles. The bridges are supported by 9,500 concrete pilings and feature bascule spans over the navigation channel 8 miles south of the north shore. The southern terminus of the Causeway is in Metairie, Louisiana, a suburb of New Orleans. The northern terminus is at Mandeville, Louisiana. #NewOrleans #Pontchartrain #Bridges
Lake Pontchartrain is the largest lake in Louisiana and the second largest saltwater lake in the U.S. It is actually an estuary,it is a partially enclosed coastal body of water with at least one river spilling into it and open access to the ocean. It's beautiful!
Lake Ponchatrain is the second-largest inland saltwater body of water in the United States, after the Great Salt Lake in Utah, and the largest lake in Louisiana. As an estuary, Pontchartrain is not a true lake. (Pictured: the Ponchatrain Causeway)

Lake Pontchartrain Causeway, Louisiana This bridge rises just 16 feet above the waters of Lake Pontchartrain, but the real fear factor is that it never seems to end—it spans nearly 24 miles from Metairie to Mandeville, LA. (Once you reach roughly the eight-mile mark, say goodbye to land visibility.)
