Bridges are magnanimous engineering feats that have made lives much easier. They have made sure that we can travel hassle-free to places in trains, cars, and metros. Bridges have also made some places accessible.
From the stepping stones that acted as bridges in the earliest of times, we have sure come a very long way! Boardwalks were one of the earliest forms of bridges, and their construction can be mapped to being completed around 6,000 years ago. These days construction of bridges is not as simple as it is used to be, and it can take years for the design to be finalized, as the construction can pose various complex engineering problems. There are multiple types of bridges, depending on the construction and the principle by which it is held in place.

Longest bridges in the world

The length of a bridge is a factor that contributes to the design as much as any other factors. And the longest bridges in the world are now primarily in China.

1. Danyang-Kunshan Grand Bridge, China

This bridge is longest in the world with a length of almost 160.4 kilometers or 102.4 miles. It is a rail flyover, more commonly a viaduct on the Beijing Shanghai High-speed railway. The Danyang-Kunshan Grand lies in the Jiangsu Province of China, passing over the Yangtze River Delta and the Yangcheng Lake in Suzhou. Its construction began in 2006 and was completed in 2010. Finally opened to trains on 30th June in 2011, this bridge holds the Guinness World record for the longest bridge. It was built at a cost of a whopping 8.5 billion US Dollars.

2. Changhua-Kaohsiung Viaduct, Taiwan

The second longest railway flyover in the world, this bridge serves the Taiwan High-Speed rail. Its length is 157.317 kilometers and was opened in January 2007. Till December 2012, more than two hundred million railway passengers have been carried over it. The Changhua-Kaohsiung Viaduct begins from Baguashan in Changhua County and ends at Zuoying in Kaohsiung. The bridge is earthquake-resistant, which enables trains to stop over it during earthquakes and also enables it to be easily repaired after an earthquake.

3. Cangde Grand Bridge, China

This third longest bridge in the world is also a part of the Beijing Shanghai High-speed railway, just like the Danyan-Kunshan. Built on a total of 3092 piers, it was finished in 2010. The bridge has been constructed in a way that it can withstand seismic pressures.

4. Tianjin Grand Bridge, China

The 113,700 meter-long Tianjin viaduct runs between Langfan and Qingxian and was completed in 2010. In 2011, it was also given the Guinness World Record for the second longest bridge. But now, its the fourth longest bridge in the world. This bridge is also a part of the Beijing- Shanghai High-speed Railway.

5. Weinan Weihe Grand Bridge, China

The Weinan Weihe Grand lies in the Zhengzhou- Xi’an High-speed Railway line and is 79.732 kilometers long. This bridge crosses over many rivers, highways and railway lines, including the Wei River, which the bridge crosses over twice. The construction of the bridge was completed in 2008, but the line was opened to rail on February 6, 2010.

6. Bang Na Expressway, Thailand

This six-lane elevated highway in Thailand is fifty-five kilometers long and stands at the sixth place on the list of the world’s longest bridges. This bridge is the world’s longest car bridge and was the longest bridge in the world from 2002 to 2004. This tolled expressway has various entries and exits.

7. Sheikh Jaber Al-Ahmad Al-Sabah Causeway, Kuwait

Built at a cost of USD 3 billion, this mega-bridge project spans the entire Bay of Kuwait. This bridge has been named after the Sheikh Jaber Al-Ahmad Al-Sabah of Kuwait, who reigned during the Gulf War for his contribution towards the development of Kuwait. This bridge is 48.5 kilometers long and is made of concrete and steel. Inaugurated about two months ago, this bridge connects the Kuwait City with the Silk Road, a place that aims to promote Kuwait as a tourist destination.
