Top 10 Longest Bridges in the World That Broke All Records (2025)
When it comes to infrastructure, few structures match the scale and ambition of the world’s longest bridges. These engineering feats span cities, rivers, lakes, and entire regions, linking transport systems, accelerating economies, and redefining what is possible.
This article ranks the 10 longest bridges in the world by total linear length as of 2025. These records measure full bridge length, including approaches and spans, capturing accurate engineering scale and impact.
While many of the top spots are held by Chinese high-speed rail viaducts, a new wave of massive elevated highways is emerging in countries like Bangladesh and the Philippines.
Key Definitions for Context:
Total Length
: Includes the full continuous span of the bridge structure, not just the segment over water or a valley.
Main Span
: The longest unsupported stretch between two towers or piers.
Continuous Over Water
: Total bridge length uninterrupted over a water surface.
Aggregate Over Water
: Total length of segments over water, even if separated by land.
Understanding these definitions is crucial. For example, the Lake Pontch
The Longest Bridges In The World
Bridges come in all shapes and sizes. Some are not much more than a handful of planks spanning a trickling creek, while other titanic engineering projects stretch significantly further than the naked eye can accommodate. Imagine driving for an hour at highway speeds and still being on the same bridge! That is the kind of scale we are talking about when it comes to the longest bridges in the world. While this is a global list, China is the clear king of these mega structures, claiming seven of the top ten spots. With that said, because there are competing ways to measure the exact lengths of these connecting roads and railways, it is worth noting that the rankings can shift slightly across different metrics.

What is the Longest Bridge in the World?
Humans have been constructing bridges of some sort since ancient times. Bridges are used to cross waterways and valleys in order to shorten distances and to reduce travel time. This article takes a look at some of the longest bridges in the world, the majority of which are found in China.
The 10 Longest Bridges in the World
1. Danyang-Kunshan Grand Bridge, China (164,800 Meters)
The Danyang-Kunshan Grand Bridge, on the Beijing-Shanghai high speed railway in China, is the longest bridge in the world. It covers a total distance of 164,800 meters, which is around 102.4 miles. Ten thousand contractors took four years to complete the construction of the Danyang-Kunshan, which was finished in 2010. The railway began operation in 2011. In the same year, this bridge was inducted into the Guinness Book of World Records.
2. Changhua-Koahsiung Viaduct, Taiwan (157,317 Meters)
The Changhua-Koahsiung Viaduct is the second largest bridge in the world, spanning 157,317 meters. The bridge comprises a portion of Taiwan’s high-speed railway system which runs along the west coast of the island. It opened for service in January of 2007. By Decembe
What's the world's longest bridge?
The world's longest bridge is the Danyang–Kunshan Grand Bridge in China, part of the Beijing-Shanghai High-Speed Railway, according to Encyclopaedia Britannica. The bridge, which opened in June 2011, spans 102.4 miles (165 kilometers).
China constructed the Danyang–Kunshan Grand Bridge in just four years, employing 10,000 workers, at a cost of about $8.5 million, according to Encyclopaedia Britannica. It crosses low rice paddies, part of the Yangtze River Delta, with just a few miles of the bridge actually crossing the open water of Yangcheng Lake in Suzhou. The bridge averages about 100 feet (31 meters) off the ground.
