Top 10 longest bridge in the world
10. Atchafalaya Basin Bridge – 29,290 metres (96,095 ft)
The Atchafalaya Basin Bridge, also known as the Louisiana Airborne Memorial Bridge, is a pair of parallel bridges in the U.S. state of Louisiana between Baton Rouge and Lafayette which carries Interstate 10 over the Atchafalaya Basin. With a total length of 96,095 feet (29,290 m) or 18.2 miles, it is the second-longest bridge in the US and fourteenth-longest in the world by total length.The bridge includes two exits: one for Whiskey Bay (LA 975) and another for Butte La Rose (LA 3177). While the bridges run parallel for most of their length, they merge when crossing the Whiskey Bay Pilot Channel and the Atchafalaya River. The average daily traffic count is (as of 2011) 24,540 vehicles.Accidents occur frequently near the two river crossings as both are very narrow and lack shoulders. Accidents along the bridge can be problematic as the Atchafalaya Basin is sparsely inhabited. In 1999, Governor Mike Foster lowered the speed limit on the bridge from 70 MPH to 60 MPH. In 2003, the Louisiana Legislature enacted new traffic regulations for the bridge. The speed limit for 18-wheelers was lowered to 55 MPH, and they must remain in the right lane while crossing the bridge.
9.Shanghai Maglev line – 29908 metres (98123 ft)
The Shanghai Maglev Train or Shanghai Transrapid (“Shanghai Maglev Demonstration Operation Line”) is a magnetic levitation train, or maglev line that operates in Shanghai, China. The line is the first commercially operated high-speed magnetic levitation line in the world.Construction of the line began in March 1, 2001, and public commercial service commenced on 1 January 2004. The top operational commercial speed of this train is 431 km/h (268 mph), making it the world’s fastest train in regular commercial service since its opening in April 2004. During a non-commercial test run on 12 November 2003, a maglev train achieved a Chinese record speed of 501 km/h (311 mph). The Shanghai Maglev has a length of 153m, a width of 3.7m, a height of 4.2m and a three- class, 574- passenger configuration.
8.Donghai Bridge – 32500 metres (106600 ft)
Donghai Bridge is a Chinese bridge counted among the longest cross-sea bridges in the world. It was completed on December 10, 2005. It has a total length of 32.5 kilometres (20.2 mi) and connects mainland Shanghai’s Pudong New Area with the offshore Yangshan Deep-Water Port in Zhejiang’s Shengsi County. Most of the bridge is a low-level viaduct. There are also cable-stayed sections to allow for the passage of large ships, the largest with a span of 420 m. Donghai Bridge is part of the S2 Hulu Expressway.The bridge has a long and narrow speedway and does not allow vehicles that do not meet the weight requirements.
7.Runyang Bridge -35660 metres (116990 ft)
The Runyang Yangtze River Bridge is a large bridge complex that crosses the Yangtze River in Jiangsu Province, China, downstream of Nanjing. The complex consists of two major bridges that link Zhenjiang on the south bank of the river and Yangzhou on the north. The bridge is part of the Yangzhou–Liyang Expressway. Construction of the bridge complex began in October 2000 and was completed ahead of schedule. The bridge cost 5.8 billion Yuan (about US$ 700 million). The complex opened to traffic on April 30, 2005. The total length of the bridge complex is about 35.66 kilometres (22.16 mi). In between the two bridges is the island of Shiyezhou.Prior to the bridge’s completion, round-the-clock ferry services operated across the river. It took about 40 minutes to reach the Zhenjiang Railway Station from Yangzhou.
6.Hangzhou Bay Bridge -35673 metres (117037 ft)
Hangzhou Bay Bridge is a highway bridge with a cable-stayed portion across Hangzhou Bay in the eastern coastal region of China. It connects the municipalities of Jiaxing and Ningbo in Zhejiang province.Construction of the bridge was completed on June 14, 2007, and an opening ceremony was held on June 26, 2007. The bridge was opened to public May 1, 2008, after a considerable period of testing and evaluation. The bridge shortened the highway travel distance between Ningbo and Shanghai from 400 km (249 mi) to 180 km (112 mi) and reduced travel time from 4 to 2 hours. At 35.673 km (22 mi) in length, Hangzhou Bay Bridge was among the ten longest trans-oceanic bridges.
5.Yangcun Bridge -35812 metres (117493 ft)
Yangcun Bridge is the high-speed railway with the length of 35,812 m (117,493 ft) and was completed in 2007.
4.Manchac Swamp bridge- 36710 metres (120440 ft)
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.
3.Lake Pontchartrain Causeway – 38422 metres (126122 ft)
The Lake Pontchartrain Causeway, sometimes only the Causeway, is a causeway composed of two parallel bridges crossingLake Pontchartrain in southern Louisiana, United States. The longer of the two bridges is 23.83 miles (38.35 km) long. The southern terminus of the Causeway is in Metairie, Louisiana, a suburb of New Orleans. The northern terminus is at Mandeville, Louisiana.Since 1969, it was listed by Guinness World Records as the longest bridge over water in the world; in 2011 in response to the opening of the allegedly longer Jiaozhou Bay Bridge in China, Guinness created two categories for bridges over water: continuous and aggregate lengths over water. Lake Pontchartrain Causeway then became the longest bridge over water (continuous) while Jiaozhou Bay Bridge the longest bridge over water (aggregate).
2.Bang Na Expressway -54000 metres (177000 ft)
The Bang Na Expressway (full name: Bang Na – Bang Phli – Bang Pakong Expressway), officially Burapha Withi Expressway , is a 55 km long six-lane elevated highway in Thailand. It is a toll road and runs above National Highway route 34, (Bang Na–Bang Pakong Highway) owned by the Expressway Authority of Thailand (EXAT).The highway is elevated onto a viaduct that has an average span length of 42 meters. It is a 27-meter wide box girder bridgeand was completed in January 2000. It took 1,800,000 cubic meters of concrete to build the bridge. The structure was built using a design-build contracting method. The columns and superstructure were designed by Jean M. Muller (U.S.) and the alignment and foundations were designed by Asian Engineering Consultants (Thailand). The owner’s engineer was Louis Berger Group (U.S.) and the project was built by a joint venture of Bilfinger + Berger (Germany) and Ch. Karnchang (Thailand).
