Trying to establish the longest bridge on earth is quite a difficult task. In the past few years there have been several “dimension wars” that were fought over the measurement lengthwise of the globe’s longest bridges. The major reason for all this is due to the reason that it is not easy to define what precisely makes up a bridge. Does it need to be over the waters? Are the elevated road ways in any way bridges? What if just a part of the bridge is over the waters? Though these are reasonable questions if you’re competing for the Guinness World Record, we won’t discriminate against any type of bridge. Therefore with all that said, here are the 5 of the longest bridges in the world.
1. The Danyang–Kunshan Grand Bridge
Danyang–Kunshan Grand Bridge is the planet’s longest bridge. It is a 102.4 miles (164.8 kilometers) long viaduct on the Shanghai-Beijing High-Speed Railway, a place where geography is characterized by canals, lowland rice paddies, rivers and lakes.
2. The Bang Na Expressway
The Bang Na Expressway is the second-longest bridge in the world. It is 55 km long six-lane impressive highway in Thailand. It’s often considered to be among the longest bridges on earth but it is not included in some lists because it doesn’t cross a body of water for the largest part of its length. The largest water body it crosses is Bang Pakong River.
3. The Lake Pontchartrain Causeway
This is among 5 of the longest bridges in the world. The Causeway, or the Lake Pontchartrain Causeway, consists of 2 parallel bridges which are the longest bridges on earth by total length. These bridges cross Lake Pontchartrain in the southern Louisiana. The longer of these two bridges is 38.42 km (23.87 miles) long. The parallel bridges are supported by more than 9,000 concrete pilings. The bridges are characterized by bascule spans over navigation channel 13 km (8miles) southern part of the north shore. The Causeway’s southern terminus is in Metairie, Louisiana, which is a suburb of the New Orleans. Northern terminus is at the Mandeville, Louisiana.
4. The Donghai Bridge
Donghai Bridge (factually “the East Sea Grand Bridge”) is actually the longest cross-sea bridge on planet and the longest bridge that’s in Asia. It was completed on 2005 December, 10. It has a length of 20.2 miles (32.5 kilometers) and connects the offshore Yangshan and Shanghai deep-water port in the popular country China. The largest part of the bridge is actually a low-level viaduct. There are as well cable-stayed sectors to allow for the passage of any large ships, largest with about span of 420 m.
5. The Manchac Swamp Bridge
Manchac Swamp Bridge is a double concrete trestle bridge, found in the US, in the state of Louisiana. It’s located just arout Lake Pontchartrain, which is a lake famous for its unbelievably long bridges.
We have traveled from continent to continent to bring you the top amazing longest bridges that have ever been built. Take a visit through the countdown of the bridges with interesting and unique features. There are thousands of bridges across the globe that vary in function, size and design. Therefore, the aforementioned is a list of the top five longest bridges in the world.
