The World's Longest Bridge in New Orleans

The Lake Pontchartrain Causeway is the longest overwater highway bridge (28 miles or 38 KM) in the world (the Guinness World Record).

The first span was built in 1955 - 1956 and opened August 30, 1956.

The second span was built in 1967 - 1969 and opened May 10, 1969.

The twin spans are 80 feet apart and connected by seven crossovers which function as pullover bays for motoring emergencies.

More than 10 million vehicles traveled the Causeway each year.

Lake Pontchartrain is 610 square miles and was named for the Count de Pontchartrain, minister of the marine during the regime of France's "Sun King" for whom Louisiana was named.

Lake Pontchartrain and its Causeway, the world's longest bridge, comprise one of America's most scenic attractions.
