Runyang Bridge

Runyang Yangtze River Bridge is located on the west side of Zhenjiang and Yangzhou in Jiangsu Province. It is the largest span composite bridge in China. In the process of construction, it has overcome many worldwide technical problems.

Construction started in 2000 and completed in 2005.

At that time, the bridge was a modern super large bridge project with the largest engineering scale, the highest construction standard, the largest investment, the most complex technology and the highest technical content in China, and it was the first combined bridge with both rigidity and flexibility in China.

Construction process

After investigating the situation around Zhenjiang and Yangzhou ferry, Wang Zhong, a Yangzhou scholar in the Qing Dynasty, wrote a proposal on building a floating bridge at Jingkou, which proposed the idea of building a floating bridge between Guazhou Jinshan Zhenjiang, and became the initiator of building Runyang Yangtze River Bridge.

In 1919, Dr. Sun Yat Sen, the great pioneer of China's democratic revolution, planned two Yangtze River bridges in his book industrial plan. One is the Wuhan Yangtze River Bridge in the middle reaches, and the other is the Zhenjiang Yangzhou Yangtze River Bridge in the lower reaches. This is the first person who proposed to build a modern Yangtze River bridge between Zhenjiang and Yangzhou.
