Danyang–Kunshan Grand Bridge in China holds record as the longest bridge worldwide

The world's longest bridge is the Danyang–Kunshan Grand Bridge in China, part of the Beijing-Shanghai High-Speed Railway. The bridge, which opened in June 2011, ps 102.4 miles (165 kilometers). Another part of that train line, the 70.8-mile (114-km) long Langfang–Qingxian viaduct, is the second-longest bridge in the world, according to Live Science.

Construction

The construction of Danyang-Kunshan Grand Bridge wasn’t an easy task. Being a mega dream project, it was expected to bring a boom in China’s communication infrastructure. China gave a boost to its industrial capabilities from early 2000 by planning to construct several long bridges. To fulfill that ambition, building the longest bridge in Asia was the need of the hour. With the construction of Danyang-Kunshan Grand Bridge, China easily overcame its massive public and industrial transportation system. This bridge plays a pivotal role to connect the country’s prominent industrial hubs, Travel Triangle said.

Notable facts

By 2006 though, a concrete plan was made and the construction work began thereafter. Here are some of the notable facts related to the construction of this famous bridge:

1. It took 4 years extensive efforts to construct Danyang-Kunshan Grand Bridge

2. Danyang-Kunshan Grand Bridge is 164.8 kilometers long

3. An approximate height of this bridge from the ground is 100 feet

4. This bridge has already broken the record of the world’s largest water bridge Louisiana, which is 24 miles long in the Lake Pontchartrain Causeway

5. A specific portion of this bridge at 5.6 miles passes across the Yangcheng Lake in Suzhou open waters

6. A huge amount of steel cables and 450,000 tons of steel structure were used to construct this portion of the bridge

8. This bridge has been constructed in a way that it is capable to bear natural disasters like typhoons and at least 8 magnitude earthquakes

9. This bridge can bear the direct impact from naval vessels weighing 300,000 tons or less

What"s the World"s Longest Bridge?
Danyang–Kunshan Grand is the longest brigde in the world currently.

World's longest road bridge

The world's longest road bridge is the 34-mile (55-km) long Bang Na Expressway in Thailand, a six-lane elevated highway that crosses only a bit of water, the Bang Pakong River. Constructing the massive bridge required more than 1,800,000 cubic meters of concrete.

World's longest continuous bridge over water

The world's longest continuous bridge over water is the Lake Pontchartrain Causeway in southern Louisiana. The causeway is actually two parallel bridges, with the longer of the two measuring 23.83 miles (38 km). The bridges are supported by 9,500 concrete pilings.

Louisiana's famous bridge faced a challenger in 2011, when China claimed that its Jiaozhou Bay Bridge was the longest pning water. Guinness World Records decided to split the title into two parts, stating that the 26.4-mile (42.5-km) long Jiaozhou Bay Bridge is the longest bridge over water in aggregate, while the Pontchartrain is the longest continuous bridge. In Jiaozhou, land bridges and sea tunnels make up parts of the overall structure.
