Construction of the main line of the Shenzhen-Zhongshan bridge in South China was completed on Nov 28.
Connecting the Shenzhen Airport Interchange and the Guangzhou-Shenzhen Riverside Highway, the Shenzhen-Zhongshan bridge stretches across the Pearl River Estuary and links Shenzhen, Guangzhou and Zhongshan in South China's Guangdong Province.
With a total length of 24 kilometers, the eight-lane bridge has a designed speed of 100 kilometers per hour and is an integral cross-sea project that includes bridges, islands and tunnels.

The 1,170-meter Zhongshan bridge of the project has a double-tower cable-stayed structure with a standard width of 40.5 meters. It has the widest cross-sea steel box girder of its kind in the world.
About 91 meters over the sea surface, the Lingdingyang bridge of the Shenzhen-Zhongshan bridge project has a main span of 1,666 meters and a 270-meter main tower. It has a global height record net headway of 76.5 meters, and is also the world's largest offshore steel box girder suspension bridge.
The undersea tunnel of the Shenzhen-Zhongshan bridge is about 6.8 kilometers, including about 5 kilometers of immersed pipeline utilizing 32 pipe joints and one final joint. It is the world's longest and widest undersea steel-tube-shell immersed tunnel.

The Shenzhen-Zhongshan bridge is the only passage linking the Shenzhen-Dongguan-Huizhou and Zhujiang-Zhongshan-Jiangmen city clusters. Once operational, it is expected to optimize the traffic and transportation system of the eastern and western banks of the Pearl River Delta region and improve connectivity between cities like Hong Kong, Macao, Guangzhou, Zhongshan, Shenzhen and Zhuhai.
China Railway Liuyuan Group Co., Ltd., China Railway Major Bridge Reconnaissance and Design Institute Co., Ltd., China Railway Major Bridge Engineering Group Co., Ltd., China Railway Tunnel Stock Co., Ltd. and China Railway Hi-Tech Industry Co., Ltd., all subsidiaries of China Railway Construction Corporation Limited, participated in construction, design, consultation and supervision of the project.
