The world's longest bridge in China: More than a hundred kilometers long, costing hundreds of trillions!

The Danyang - Con Son Bridge in China is the longest bridge in the world today, with a length of more than 164km and took just over 3 years to build at a cost of 100,000 billion VND.

Bridges come in all shapes and sizes, from the world's longest suspension bridge connecting Europe and Asia, to a bridge woven from living roots in India. However, the Danyang - Kunshan Bridge in China simultaneously holds both the title of longest bridge and second longest bridge in the world, according to IFL Science.

Danyang - Kunshan Bridge is located in Jiangsu province (China), has a total length of more than 164.8km and is considered the "longest bridge in the world" today. Due to the length and difference in terrain below the bridge , it is both a viaduct and a cable suspension bridge in each section. Viaducts are bridges supported by a series of pylons or arches below, while cable suspension bridges use tension cables running diagonally from pylons above the bridge. The Dan Duong - Con Son bridge is so long that a section of the bridge called the Lang Phuong - Thanh Huyen viaduct is even considered the second longest bridge in the world with a length of 114km.

The Danyang - Kunshan Bridge is about 31m high above the ground, includes more than 4,500 box girders weighing 900 tons and was completed by more than 10,000 workers after more than 3 years at a total cost of 30 billion yuan . The bridge was officially put into use in 2011.

Because it is located on the Beijing - Shanghai high-speed railway , Danyang - Kunshan is also considered the 'longest railway bridge in the world'.

The Beijing-Shanghai high-speed railway connects China's two largest cities. Every day, hundreds of thousands of passengers travel on this route. However, the project encountered many obstacles in the southern Jiangsu region due to topographic, geological, hydrological and economic factors.

To minimize the cost of land clearance to build high-speed railways, Chinese designers came up with the bold idea of ​​bridging across rivers instead of highways on land . That is the purpose of the Dan Duong - Con Son bridge being built.

The successful construction of the Danyang - Con Son bridge marks China's great achievements in the field of infrastructure construction.

'Danyang - Con Son Bridge is definitely a remarkable engineering project and will leave an indelible mark on the world' , Chinese media praised.

The Danyang - Kunshan Bridge has now become a beautiful scenic spot in the Jiangsu region. Elevated stations along the bridge also bring development opportunities to cities along the route. Cities rich in Chinese cultural identity such as Changzhou, Wuxi, Suzhou and Kunshan are more closely connected.

Although the construction process was relatively rushed, the bridge was also designed to withstand a series of natural disasters affecting the area such as earthquakes and storms as well as a direct hit of about 300,000 tons from a naval ship. The estimated lifespan of the bridge is more than 100 years.
