Revision as of 03:08, 1 July 2011
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.
Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges, the next longest design, are practical for spans up to around 1 km. Thus, the 17 longest bridges on this list are all currently the 15 longest spans of all types of vehicular bridges.
Completed suspension bridges
This list includes only completed suspension bridges that carry automobiles or trains. It does not include cable-stayed bridges, footbridges or pipeline bridges.
Bridges under construction
Most of the large suspension bridges built in recent years have been in the People's Republic of China. As the following list shows, most of the bridges under construction are also in China.
Name | Location | Main span |
Scheduled opening date |
Notes |
---|---|---|---|---|
Yi Sun-sin bridge | South Korea | 1,545 m (5,069 ft) | 2012 | |

Taizhou Bridge | near Taizhou, China | 1,080 m (3,540 ft) | 2010 | Two 1,080 m (3,540 ft) spans connecting three towers.[112] |
Ma'anshan Bridge | China | 1,000 m (3,300 ft) | 2010 | Two 1,000 m (3,300 ft) main spans.[113] |
Yingwuzhou Bridge | China | 850 m (2,790 ft) | 2015 | Two 850 m (2,790 ft) main spans.[114] |
Aizhai Bridge | China | 1,146 m (3,760 ft) | 2012 | [115] |
Lishui Bridge | China | 856 m (2,808 ft) | 2012 | [116] |
Nanxi Bridge | China | 820 m (2,690 ft) | 2011 | |
Eastern section of the San Francisco – Oakland Bay Bridge | San Francisco – Oakland, California, USA | 385 m (1,263 ft) | 2013 | This will be the largest self-anchored suspension bridge ever constructed. With one tower, it will have two asymmetric spans of 180 and 385 m. |
Hardanger Bridge | Hardangerfjorden, Norway | 1,310 m (4,300 ft) | 2013 | Construction start was in January 2009, and is estimated to be completed in 2013.[117] |
Planned and proposed bridges
Name | Location | Main span |
Status | Notes |
---|---|---|---|---|
Sunda Strait Bridge | Java to Sumatra, Indonesia | about 3,000 m (9,800 ft) | Preliminary work | This project has been approved by the Indonesian government. If completed, it will not only be the world's longest suspension bridge (26 km), but will also have a main span of about 3,000 m (9,800 ft)—roughly fifty percent longer than the current record.[118] |
Unnamed | Qiongzhou Strait, China | about 3,000 m (9,800 ft) | Preliminary work | A suspension bridge is being considered to cross the 22.5 km wide Qiongzhou Strait.[119] One design consists of four bridges strung together with four main spans of 2,000 m, two main-spans of 1,800 m, five anchorages and 10 towers.[120] If completed this bridge will assume six of the top seven longest spans. |
Unnamed | Aizhai Gorge in Hunan province, China | 1,176 m (3,858 ft) | Planned | [121] |
İzmit Bay Bridge | Marmara Sea, Turkey | 1,688 m (5,538 ft) | Planned | Bidding is expected to start in June 2009.[122] The original design called for a long span, but recent images depict several shorter spans.[123] |
Chacao Channel bridge | Chiloé to mainland Chile | 1,100 m (3,600 ft) | On hold | This unusual design has two main spans of 1,055 m and 1,100 m without an anchorage between them. Construction was supposed to begin in 2007 and completed in 2012, but because of cost overruns, the project is now on hold. |
Strait of Messina Bridge | Sicily to mainland Italy | 3,300 m (10,800 ft) | Planned | The project was canceled on 11 October 2006 by the Romano Prodi-led government amid controversy concerning the bridge's cost and feared Mafia influence.[124] The new government from 2008 led by Silvio Berlusconi wants to pick up the project again. Preliminary works will begin in December 2009. The main construction is expected to begin in the 2010s. |
Gibraltar Bridge | Spain to Morocco | ? | Proposed | Some designs have suspension spans of several miles. The suspension cables of a very long bridge might be suspended from the ends of cable-stayed struts extending diagonally from huge pylons. However, as of 2008, the feasibility of a tunnel is being considered instead. |
Hålogaland Bridge | Narvik, Norway | 1,345 m (4,413 ft) | Plans under consideration | The bridge will reduce the distance between Narvik and Bjerkvik by 17 km. The government of Norway has declared that it wants to build it, with construction to start possibly in 2011, and an opening date in 2015.[125] See no:Hålogalandsbrua. |
Taizhou Bridge | Taizhou, Jiangsu, China | 1,080 m (3,540 ft) | under construction |
