Published on

Have you ever marveled at the vast and lengthy engineering art of bridges? Bridges have been significant in human history for connecting people from one location to another. Most bridges’ construction aims to serve as crossing pathways across the water area. In this article, we will learn about the world’s top 10 longest bridges.

Most of the leading longest bridges in the world are in Asia, specifically China. Each of these engineering accomplishments combines creativity and practicality, impacting the world’s infrastructure and bringing societies together in once unimaginable ways.

Sharply, let’s venture into the exclusive list of the top 10 longest bridges in the world.

9 Line 1 (Wuhan Metro) China 23.6 mi (38 km)
10 Manchac Swamp Bridge United States 22.7 mi (9.785 km)

10. Manchac Swamp Bridge

The Manchac Swamp Bridge is one of the longest overwater bridges in the world. At the local level, it is among the top 10 longest bridges in the U.S.

Located in the U.S. state of Louisiana, it goes over the Manchac Swamp for 22.8 miles and takes up one-third of Interstate 55.

In 1979, the Manchac Swamp Bridge was built over the Manchac Swamp so that cars could get through. It is also part of U.S. Route 51 and became open to the public in 1979.

This bridge was created through the collaboration of 600 specialists and ten years of planning. Many of its offshore components were manufactured on land before being transported to sea. The construction cost of the Manchac Swamp Bridge is over $161 million, which is about $460 million when calculated in 2020’s dollars.

9. Line 1 (Wuhan Metro)

Wuhan, Hubei, is home to the elevated metro line known as Line 1 of the Wuhan Metro. It boasts the world’s longest stretch of continuous metro viaduct.

According to Wikipedia, Wuhan became the fifth city in mainland China to have a metro system when Line 1 opened on July 28, 2004, following Beijing, Tianjin, Shanghai, and Guangzhou.

Because it is elevated, this is China’s first Metro line, wrongly referred to as a light rail line in Chinese terminology. Initially, a branch line from the Second Wuhan Yangtze River Bridge to Wuchang District was proposed.

Even before the branch line’s 1995 opening, the Second Wuhan River Bridge included a space in the central median for Line 1 trains to operate. But in 2003, as work on the bridge was progressing, the reservation was taken out to make room for extra lanes of traffic.

8. Lake Pontchartrain Causeway

Lake Pontchartrain Causeway is the eighth-longest bridge in the world and the longest in the United States of America.

The Lake Pontchartrain Causeway is a concrete structure that traverses Lake Pontchartrain in southeast Louisiana, the United States, using two parallel bridges. The longer bridge measures about 23.83 miles in length. The causeway’s southernmost point is at Metairie, Louisiana, a suburb of New Orleans on the south shore. Mandeville, Louisiana, a New Orleans north shore suburb, serves as the northern terminus.

It was recognized by Guinness World Records as the world’s longest bridge over water from 1969 until 2011.

There are up to 9,500 concrete pilings supporting the bridges. The navigation canal is crossed by the two bridges’ bascule, which is located 8 miles (13 km) south of the north coast. The causeway has been used as a toll bridge since it was constructed.

7. Beijing Grand Bridge

The Beijing Grand Bridge is also one of the longest bridges in the world over water. This bridge is a railway viaduct on the Beijing-Shanghai High-Speed Railway in Beijing, measuring 48.15 kilometers (29.92 miles).

The bridge was built to withstand earthquakes as well as high-speed rail forces. The bridge construction project was completed as part of China’s ambitious aim to develop its high-speed rail network.

6. Bang Na Expressway

The $1 billion Bang Na Expressway in Bangkok, Thailand, is not the longest bridge in the world, but it is among the most extensive precasting operations ever conducted.

The box girders were match-cast and post-tensioned with dry joints and external longitudinal tendons in situ. The Bang Na Expressway, also known as the Burapha Withi Expressway, is a six-lane, 54-kilometer-long elevated highway in Thailand. An achievement of Sukavich Rangsitpol, deputy prime minister of the Chuan Leekpai Cabinet (1992–1995), was the construction of the bridge.

The Bang Na Expressway was developed by the Expressway and Rapid Transit Authority of Thailand (ETA) and designed by the late Louis Berger. The structure was constructed using the design-build procedure. This bridge is currently positioned among the world’s longest bridges.

5. The Weinan Weihe Grand Bridge

In China, the Zhengzhou–Xi’an High-Speed Railway connects Zhengzhou and Xi’an via the Weinan Weihe Grand Bridge. The Weinan Weihe Grand Bridge is also one of the longest bridges in the world.

The 79.3-kilometer bridge crosses the Wei River twice and numerous other rivers, including the Ling River, Luofu River, Xi River, Shi Di River, and countless others. During the construction of the Weinan Weihe Grand Bridge, at least 10,000 individuals, 2,300,000 cubic meters of concrete, and 45,000 tons of steel were utilized.

It was the longest bridge in the world when finished, but two new bridges on the Beijing-Shanghai High-Speed Railway completed in 2010 exceeded it. However, the railroad line began operation on February 6, 2010, despite the bridge’s completion in 2008.

4. Cangde Grand Bridge

Cangde Grand Bridge is the fourth-longest bridge in the world. The bridge, a section of the Beijing-Shanghai High-Speed Railway, was completed in 2010 and is the third longest on the line.

The bridge was built with earthquake resistance in mind. The Cangde super-large bridge has 3092 piers and is 105.81 km (65.75 mi) long. The three-hour journey between Hong Kong, Macau, and mainland China may be completed in just 30 minutes, thanks to the network of bridges on the railway route.

3. Tianjin Grand Bridge

The Tianjin Grand Bridge is also among the longest bridges in the world. It spans a distance of 113.7 kilometers (70.6 miles) between Langfang and Qingxian and functions as a railway viaduct for the Beijing-Shanghai High-Speed Railway. The Tianjin Grand Bridge was officially opened in 2011 and is the third-longest bridge in the world.

The elevated track’s design was selected to avoid constructing numerous individual structures for crossing roads and railways and to reduce the construction time.

A railroad trestle needs 28.4 hectares per kilometer of track, but the bridge itself only needs 10.9 hectares, which is less than half as much land.

The bridge has box girders that are 32 meters long and weigh 860 tons each. These rafters were made in two places near the bridge. They were then moved to the installation site on an already-built part of the bridge and set on the piers by a special crane.

2. Changhua–Kaohsiung Viaduct

The second-longest bridge in the world, the Chang-hua-Kao-hsiung Viaduct, achieved completion in 2007. The Chang-hua-Kao-hsiung Viaduct opened in 2007 and is the world’s second-longest bridge. As part of Taiwan’s High-Speed Rail network, the bridge spans 157.3 kilometers (97.8 miles) from Zouying in Kao-hsiung to Baguashan in Chang-hua County.

The railway was built across a vast network of viaducts that were meant to be earthquake resistant. This allows trains to halt safely during a seismic event and provides for repairable damage after a maximum-design earthquake. According to sources, as of December 2012, it had conveyed over 200 million passengers.

1. The Danyang-Kunshan Grand Bridge

The longest bridge in the world is the Danyang-Kunshan Grand Bridge. It is a 164.8 km (102.4 miles) long bridge on the Beijing-Shanghai High-Speed Railway that connects Shanghai and Nanjing in Jiangsu province. The bridge opened in 2011 after its completion in 2010.

The project employed 10,000 individuals for four years, costing approximately $8.5 billion. Its average height is 100 meters (328 feet), traversing rice terraces and other wetlands while running roughly parallel to the Yangtze River.

The bridge was designed and constructed by China Road and Bridge Corporation (CRBC), which is a part of the China Communications Construction Company. According to Wikipedia, the CRBC is a Chinese government-funded enterprise that was formerly part of the Foreign Aid Office of the Chinese Ministry of Communications.
