Does Lake Pontchartrain Causeway is the longest high way bridge in the world?
The Lake Pontchartrain Causeway, or the Causeway, consists of two parallel bridges crossing Lake Pontchartrain in southern Louisiana. The longer of the two bridges is the longest in the world over water, measuring at 23.87 miles (38.42 km) long. It is also the second longest in the world over any terrain, behind the Bang Na Expressway landbridge. The bridges are supported by 9,500 concrete pilings. The two bridges feature bascule spans over the navigation channel 8 miles (13 km) 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.

The Lake Pontchartrain Causeway is the longest highway bridge over water in the entire world, spanning 23.9 miles from Metairie on the South Shore to St. Tammany Parish on the North Shore. The original span opened to the public over 40 years ago in 1956 as a two way, two lane bridge. In 1969 a second two lane span opened, substantially increasing the bridge’s safety when each span became a one way, two lane route for many commuters. The parallel spans are 80 feet apart and seven crossovers connect the spans for use as pull-over areas for auto emergencies. Each span has a road width of 28 feet.
