Manchac Swamp Bridge

Manchac Swamp Bridge is one of the longest bridges in the world over water

Located in the Tangipahoa Parish of the US state of Louisiana, over the Lake Maurepas the Manchac Swamp Bridge is one of the most spectacular bridges in the world.


Tucked away on the southeast border of the U.S. state of Louisiana, the bridge is a twin concrete trestle bridge carrying the I-55 road. It is 36,710 meters (120,400 feet) long. Opened in 1979, it’s one of the longest bridges in the world over water. It spans a swamp that is supposedly haunted with a Rougarou (Cajun werewolf, also known as loup-garou) and a voodoo princess. It’s quite safe to drive over the bridge despite any legends, but swamp swimmers below should be aware of the fully real alligators that float on the tranquil waters below the pier.
