Top 5 Bridges In The World 2022

Top 5 Bridges In The World – Throughout the ages, guy has been the use of structure to bridge the gaps among bodily obstacles, for the reason of supplying an smooth passage. Most of those bridges also are appeared as landmarks and are a critical a part of the infrastructures of areas across the world. Some have even end up metropolis icons due to their impact and engineering wonder. Below is a listing of the maximum well-known bridges withinside the world.

1. Danyang–Kunshan Grand Bridge

The Danyang–Kunshan Grand Bridge (simplified Chinese: 丹昆特大桥; traditional Chinese: 丹昆特大橋; pinyin: Dān-Kūn tèdà qiáo) is a 164.8-kilometre-long (102.4 mi) viaduct on the Beijing–Shanghai High-Speed Railway. It is the longest bridge in the world.

The bridge is located on the rail line between Shanghai and Nanjing in Jiangsu province. It is in the Yangtze River Delta where the geography is characterised by lowland rice paddies, canals, rivers, and lakes. The bridge runs roughly parallel to the Yangtze River, about 8 to 80 km (5 to 50 mi) south of the river. It passes through the northern edges of population centers (from west to east) beginning in Danyang, Changzhou, Wuxi, Suzhou, and ending in Kunshan. There is a 9-kilometre long (5.6 mi) section over open water across Yangcheng Lake in Suzhou.

Construction was completed in 2010 and the bridge opened in 2011. Employing 10,000 people, the project took four years and cost about $8.5 billion. The bridge currently holds the Guinness World Record for the longest bridge in the world in any category as of June 2011.

2. Changhua–Kaohsiung Viaduct

The Changhua–Kaohsiung Viaduct is the world’s second longest bridge. The bridge acts as a viaduct for part of the railway line of the Taiwan High Speed Rail network. Over 200 million passengers had been carried over it by December 2012. THSR Changhua, Yunlin, Chiayi, Tainan stations are built along this viaduct.

Completed in 2004, the bridge is 157.317 kilometers (97.752 mi) in length. The railway is built across a vast series of viaducts, as they were designed to be earthquake resistant to allow for trains to stop safely during a seismic event and for repairable damage following a maximum design earthquake. Bridges built over known fault lines were designed to survive fault movements without catastrophic damage.

3. Jiaozhou Bay Bridge

Jiaozhou Bay Bridge (or Qingdao Haiyan Bridge) is a 26.7 km (16.6 mi) lengthy roadway bridge in Japanese’s China’s Shandong province, that’s a part of the 41.fifty eight km (25.eighty four mi) Jiaozhou Bay Connection Project. The longest non-stop section of the bridge is 25.nine km (16.1 mi), making it one of the longest bridges withinside the world.

The Jiaozhou Bay Bridge transects Jiaozhou Bay, which reduces the street distance among Qingdao and Huangdi via way of means of 30 km (19 mi), as compared with the parkway alongside the coast of the bay, decreasing tour time via way of means of 20 to 30 minutes. The layout of the bridge is T-formed with the primary access and go out factors in Huangdao and the Licang District of Qingdao. A department to Hongdao Island is attached via way of means of a semi-directional T interchange to the primary span. The creation used 450,000 heaps of metallic and 2.three million cubic metres (81×106 cu ft) of concrete. The bridge is designed for you to face up to intense earthquakes, typhoons, and collisions from ships. It is supported via way of means of 5,238 concrete piles. The go segment includes beams in general 35 m (a hundred and fifteen ft) extensive sporting six lanes with shoulders.

The Jiaozhou Bay Bridge has 3 navigable sections: the Cangkou Channel Bridge to the west, the Dagu Channel Bridge to the east, and the Hongdao Channel Bridge to the north. The six hundred metres (2,000 ft) lengthy Cangkou Channel Bridge has the biggest span of the complete Jiaozhou Bay Bridge, 260 m (850 ft). The Hongdao Channel Bridge has a span of a hundred and twenty m (390 ft). The non-navigable sections of the bridge have a span of 60 m (two hundred ft).

4. Chesapeake Bay Bridge-Tunnel

The Chesapeake Bay Bridge–Tunnel (CBBT, officially the Lucius J. Kellam Jr. Bridge–Tunnel) is a 17.6-mile (28.3 km) bridge–tunnel that crosses the mouth of the Chesapeake Bay between Delmarva and Hampton Roads in the U.S. state of Virginia. It opened in 1964, replacing ferries that had operated since the 1930s. A major project to dualize its bridges was completed in 1999, and a similar project to dualize one of its tunnels is currently underway.

With 12 miles (19 km) of bridges and two one-mile-long (1.6 km) tunnels, the CBBT is one of only 12 bridge–tunnel systems in the world and one of three in Hampton Roads. It carries US 13, which saves motorists roughly 95 miles (153 km) and 1+1⁄2 hours on trips between Hampton Roads and the Delaware Valley compared with other routes through the Washington–Baltimore Metropolitan Area. As of January 2021, over 140 million vehicles have crossed the CBBT.

The CBBT was built and is operated by the Chesapeake Bay Bridge and Tunnel District, a political subdivision of the Commonwealth of Virginia governed by the Chesapeake Bay Bridge and Tunnel Commission in cooperation with the Virginia Department of Transportation. Its construction was financed by toll revenue bonds, while operating and maintenance expenses are recovered through tolls. In 2002, a Joint Legislative Audit and Review Commission (JLARC) study commissioned by the Virginia General Assembly concluded that “given the inability of the state to fund future capital requirements of the CBBT, the District and Commission should be retained to operate and maintain the Bridge–Tunnel as a toll facility in perpetuity”.

5. Hangzhou Bay Bridge

Hangzhou Bay Bridge (simplified Chinese: 杭州湾大桥; traditional Chinese: 杭州灣大橋; pinyin: Hángzhōu Wān Dàqiáo; Wu: Han-tseu-uae du-jiau) is a long 35.7 km (22.2 mi) highway bridge with two separate cable-stayed portions, built across the mouth of 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.

It is not to be confused with “Outer Hangzhou Bay Bridge”, a project under study which would ring the bay islands between Shanghai and Ningbo. An official name does not yet exist, hence the terminology clash.
