In the world, there are many bridges built with great effort and huge costs. Along with that, many bridges also hold the record for being the longest construction in the world. Danyang – Kunshan Bridge in China is currently the longest bridge in the world, with a length of more than 164 km and took only more than 3 years to build, with a cost of more than 4 billion USD.
The Danyang-Kunshan Bridge is about 31 meters above ground, consisting of more than 4,500 box girders weighing 900 tons and was completed by more than 10,000 workers after more than 3 years with a total cost of about 30 billion yuan (about more than 4.1 billion USD).
The Beijing-Shanghai high-speed railway connects China’s two largest cities. Hundreds of thousands of passengers travel on this route every day. However, the project has encountered many obstacles in the southern Jiangsu region due to topographical, 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.
Danyang – Kunshan Bridge spans 5 cities, starting from Danyang, passing through Changzhou, Wuxi, Suzhou and ending in Kunshan.
The successful construction of the Danyang – Con Son bridge marks China’s great achievements in the field of infrastructure construction.
The Danyang-Kunshan Bridge has also been considered the “longest railway bridge in the world”.
The Danyang-Kunshan Bridge is a remarkable engineering feat and will leave its mark on the world.
The Danyang-Kunshan Bridge has now become a scenic spot in Jiangsu Province. The elevated stations along the bridge also bring development opportunities to the cities along the route.
Despite the relatively rushed construction process, the bridge was also designed to withstand a range of natural disasters that affect the area, including earthquakes and typhoons, as well as a direct hit from a 300,000-ton naval vessel. The bridge is expected to have a lifespan of more than 100 years.
According to Guinness World Records, up to now, Dan Duong – Con Son bridge still holds the world record as the longest bridge in the world.
