They are some of the greatest engineering and architectural achievements ever made by humanity. Since their conception millennia ago, bridges have evolved into more complex structures capable of traversing vast distances and attracting crowds.
The meaning of bridge may need to be clarified when calculating the world’s longest bridges. A suspension bridge, which spans a picturesque trench or a big body of water, is one of the most striking representations of a bridge.
Most of the world’s longest bridges are viaducts, even though several of them have been designed specifically for that purpose.
Like an aqueduct, a viaduct is composed of a series of arches supporting an elevated walkway. Frequent use is maintaining a constant height across a large area of uneven or unstable terrain. While viaducts are quite useful, it is rare to get picturesque vistas from them.
Regardless, all 12 of the world’s longest bridges are viaducts. Southeast Asia is home to the vast majority of them. In this country, viaducts are often used for high-speed rail transit because of the smooth, level terrain they provide.
High-speed rail travel is prevalent in river valleys prone to flooding. Viaducts, on the other hand, retain valuable land and are more resistant to floods.
The Danyang Kunshan bridge in China’s Jiangsu province is the world’s longest viaduct. This bridge is over three times as long as Rhode Island is broad at over 102 miles long. While there is little doubt that the Danyang Kunshan Bridge is the longest in the world, it lacks the luxury of some of its rivals.
When traveling through the Yangtze river delta, Danyang Kunshan does not cross any huge body of water or perch on the edge of a chasm.
Even though there are more bridges in China than anywhere else, seven of the 10 longest are dedicated to high-speed rail.

The 10 longest bridges in the world, in terms of total length:
- In Danyang-Kunshan, China, there are around 547,000 people.
- Changhua-Kaohsiung, China, and Taiwan (516,132), respectively
- 380,200-person capacity bridge at China’s Canada
- Grand Bridge of Tianjin, China (373,000)

- Thailand’s Bang Na Expressway (177,000)
- The Great Wall of China’s Capital (157,982 feet)
- Louisiana’s Lake Pontchartrain Causeway (126,122)
- Wuhan Metro, Line 1 (123,976 riders) China
- Manchac Swamp Bridge, United States (population: 120,440)
We’d be negligent if we didn’t include viaducts, whose accomplishments are unquestionably impressive, albeit rather repetitious. However, a second list may be essential to grab the reader’s attention. This is a list you’ll want to share with your pals.
The world’s longest continuous suspension bridges are the focus of this list, which focuses on suspension bridges. In other words, the longest section of the bridge that isn’t supported by the rails. It’s no surprise that China has six of the 10 largest bridge spans on this list.
The Akashi Kaikyo Bridge in Japan has the world’s longest main span at 6,532 feet, connecting Kobe, Honshu, with Iwaya, Awaji. With a total height of 928 feet, Akashi Kaikyo is one of the world’s highest bridges.
However, Akashi Kaikyo’s most astonishing statistic is the quantity of material needed to build the structure.

There were around 187 million kilometers of cable utilized to support the bridge. The Earth could be circled 7.5 times with that amount of material. With a 4,200-foot main span, the Golden Gate Bridge is at a respectable 17th place on our list.
However, the Verrazzano-Narrows Bridge in New York City, which links the boroughs of Staten Island and Brooklyn, is only a hair ahead of the Golden Gate Bridge as the longest single-span in the United States.
For the longest single-span bridge in feet, see this list:
- Japan’s Akashi Kaikyo (population: 6532)
- Five thousand six hundred yangsigang bridge
- Nansha, a city of 5,538, is located in China.
- Xihoumen, China (5,413)
- 5328-Mile Great Belt of Denmark
- Osman Gazi
- South Korea’s Yi Sun-sin
