Top 10 Longest Bridges in the World

Cangde Grand Bridge

The Cangde Grand Bridge was built in 2010 in China. It spans 113 kilometres and is
part of the Beijing-Shanghai High-Speed Railway. Its unique construction includes
3,092 piers that support the elevated track. It built with earthquake resistance
in mind.

The Cangde Grand Bridge spans the Wei River in China. It is one of the world’s
longest bridges and has over 3092 piers. It is made of steel and is designed to
withstand earthquakes. This bridge also carries a high-speed train between Hong
Kong and Macau. It has a main span of 34.2 miles. It also crosses four artificial
islands. It also features three cable-stayed bridges and a 4.2-mile undersea tunnel.

The second-longest bridge in the world is the Changhua-Kaohsiung Viaduct. It is
157,317-metre-long. It is part of the Taiwan High-Speed Rail line and was built
following strict anti-seismic criteria. The third-longest bridge is the Cangde Grand
Bridge spans 115,900 metres and has 3,092 pillars.

2. Danyang-Kunshan Grand Bridge

The Danyang-Kunshan Grand bridge in Jiangsu province in China spans a staggering
164.8 kilometres. It’s one of the longest bridges in the world and an essential part
of the Beijing-Shanghai High-Speed Railway. The construction of the bridge began in
2006 and took four years. It was officially opened in June 2011. The bridge spans the
Yangtze River Delta crosses Yangcheng Lake in Suzhou. Its length and width
make it one of the longest bridges in the world.

The Danyang-Kunshan Grand bridge is one of the longest viaduct-type bridges in the
world and is part of the Beijing-Shanghai high-speed railway. Its construction took
four years and required 450,000 tons of steel. The project cost around $8.5 billion
and involved the efforts of 10,000 workers. The bridge survived severe weather,
earthquakes, and the direct impact of over 300,000 tonnes.

3: Manchac Swamp Bridge.

The Manchac Swamp Bridge in Louisiana, United States, is one of the longest
bridges in the entire world. It is a twin concrete trestle bridge that spans the
Manchac Swamp. The bridge is toll-free and was constructed in 1979. The bridge
stretches 22.8 miles across the swamp and is considered the longest bridge over
water in the world.

Another example of a long bridge is the suspension bridge, which can span a scenic
trench or a large body of water. However, most of the world’s longest bridges are
viaducts, which consist of a series of arches. Often, these structures are constructed
for stability and are not postcard-worthy.

4: Wuhan Metro Bridge.

Wuhan Metro Bridge, built in 2004, is 37 kilometres long. It’s the longest metro
viaduct in the world and serves the city of Wuhan in Hubei Province in China. It also
features spectacular views of the Manchac Swamp and is made of twin concrete
passways.

The bridge is located between Shanghai and Nanjing. It is the longest cable-stay
structure in the world, with three primary spans, each more than two miles long. The
centre span is 2,585 meters long, with side spans 1,710 meters long. The
bridge’s steel pillars are 192 meters tall, totalling 573 million
pounds.

The Guinness World Records has divided the world’s longest bridges over water into
two categories: continuous and aggregate. The Lake Pontchartrain Causeway in
Louisiana is the longest continuous bridge over water, with a total length of 38,442
meters. It’s estimate to have cost 76 million dollars to build. However, the Wuhan
Metro Bridge is the longest bridge in Hubei.
