5 Longest Bridges In The World

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. Does it have to be over water? Are elevated road ways bridges? What if only part of the bridge is over water? Although these are legitimate questions if you are competing for a Guinness World Record, for our purposes we will not discriminate against any particular type of bridge. So with that said, these are the 5 longest bridges in the world.

* Danyang–Kunshan Grand Bridge

The Danyang–Kunshan Grand Bridge is the world’s longest bridge. It is a 164.8 kilometres (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.

* Tianjin Grand Bridge

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 kilometres (70.6 mi).

* Bang Na Expressway

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

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.

* Manchac Swamp bridge

The Manchac Swamp Bridge is a twin concrete trestle bridge in the US state of Louisiana. It is located around Lake Pontchartrain, a lake well known for its incredibly long bridges, as you will see in a moment.
