Trying to determine the longest bridge in the world is no easy task. In the past several years there have been numerous “measurement wars” fought over the length of Earth’s longest bridges. The primary reason for this is that it’s hard to define what exactly constitutes a bridge. Lets take a look at 5 longest bridges in the world.
Danyang–Kunshan Grand Bridge – 164.8 kms, China
The Danyang–Kunshan Grand Bridge is the world’s longest bridge. It is a 164.8 kilometers (102.4 mi) long viaduct on the Beijing–Shanghai High-Speed Railway where the geography is characterized by lowland rice paddies, canals, rivers, and lakes.
Changhua-Kaohsiung Viaduct – 157.3 kms, Taiwan
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.
Tianjin Grand Bridge – 113.7 kms, China
Tianjin Grand Bridge is a railway viaduct bridge that runs between Langfang and Qingxian, part of the Beijing–Shanghai High-Speed Railway. It is one of the longest bridges in the world with a total length of about 113,700 m (373,000 ft), or 113.7 kilometers (70.6 mi).
Bang Na Expressway – 55 kms, Thailand
The Bang Na Expressway is a 55 km long six-lane elevated highway in Thailand. It is often considered to be one of the longest bridges in the world (until 2010 the longest) but it is excluded from some lists since it does not cross a body of water for most of its length. The largest body of water that it crosses is the Bang Pakong River.
Lake Pontchartrain Causeway – 38.3 kms, United States
The Lake Pontchartrain Causeway, or the Causeway, is considered to be the longest bridge in the United States and the longest bridge in the world over water (continuous). It consists of two parallel bridges crossing Lake Pontchartrain in southern Louisiana, United States. The longer of the two bridges is 23.83 miles (38.35 km) long.
