What is the Nanjing Yangtze River Bridge like?

Nanjing Yangtze River Bridge flies over the river like a rainbow.

Nanjing Yangtze River Bridge is located between Xiaguan in Gulou District and Qiaobei in Pukou District, Nanjing. It is the first double-deck railway and highway bridge on the Yangtze River designed and built by China.

It is of great significance in the history of bridges in China and in the history of bridges in the world. It is an important achievement of China's economic construction and an important milestone of China's bridge construction. It is of great economic, political and strategic significance and is called "the bridge to success". It is not only a symbol of new China's scientific and technological achievements and modernization, but also bears the special feelings and memories of several generations in China.

With the completion of the Nanjing Yangtze River Bridge, the train crossing time was shortened from 1.5 hour ferry to 2 minutes, and it quickly became one of the lifeblood of China's north-south traffic, playing a more decisive role in East China, creating direct economic benefits of more than 6 billion yuan.

However, since 1990, the traffic volume of the bridge has been increasing day by day. By 2002, it was overloaded day and night, with an annual total throughput of 200 million tons and an average daily traffic volume of 63,000 vehicles, which is more than three times the design capacity of 1.5 million vehicles/day. However, it seems impossible to close the bridge for maintenance.

If the bridge is closed for 10 minutes, the urban area of Nanjing will be in a state of serious traffic paralysis; If the closure exceeds 1 hour, the traffic in Jiangsu Province will be greatly affected. Railway bridge closure 1 min will cause economic losses of several hundred thousand yuan; Closed 10 minutes, the lifeline of East China Railway will be paralyzed. Therefore, the relevant departments have been unable to make up their minds to carry out thorough maintenance.
