Why you should go…

The Lake Pontchartrain Causeway is a pair of parallel bridges crossing the lake between Mandeville on the north shore and Metairie on the south. The longer span is 23.83 miles, and Guinness lists it as the longest continuous bridge over water. The first span opened in 1956 and the second in 1969, and the American Society of Civil Engineers named it a National Historic Civil Engineering Landmark in 2013. Tolls are collected only on the north shore, at the Mandeville end.
