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.

However, as newer and longer bridges have come into existence, the Weinan Weihe Grand Bridge has slipped to hold the position of the world's fifth longest bridge.
6. Bang Na Expressway, Thailand (54,000 Meters)
The Bang Na Expressway in Thailand is the world's sixth longest bridge, with a total length of 54,000 meters. Prior to 2010, it was the longest bridge in the world.

Around the world, bridges are an essential type of construction. Humans cannot live without them, and these structures have connected terrains and people for thousands of years. With the amazing feats of architecture that people have accomplished over time, it will be interesting to see how this list changes as bridges become longer and even more astounding.
