The Manchac Swamp Bridge is a twin concrete trestle bridge in the U.S. state of Louisiana. With a total length of 22.80 miles (36.69 km) it is one of the longest bridges in the world over water. Some claim it is the longest toll-free road bridge in the world. The bridge carries Interstate 55 over the Manchac Swamp in Louisiana, and represents one-third of the highway's approximately 66 miles in Louisiana. Opening in 1979, its piles were driven 250 feet (76 m) beneath the swamp and with the cost of the span being $7 million per mile to complete.
