World's Scariest Bridges
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.)
Where: Across Lake Pontchartrain between the towns of Metairie and Mandeville.
Stats: 24 miles long; 16 feet above water.
