Shenzhen-Zhongshan Bridge: A new landmark on Lingdingyang

The Shenzhen Zhongshan Link

Over the vast Lingdingyang sea area, a 24-kilometer-long passage winds like a dragon, connecting Shenzhen and Zhongshan in a major national project.

The super large cross-sea cluster project, integrating "bridges, islands, tunnels and underwater interconnectivity" opened to traffic at the end of June, cutting travel time from Shenzhen to Zhongshan from 2 hours to less than 30 minutes and making the "1-hour transportation circle" in the Guangdong-Hong Kong-Macao Greater Bay Area a reality.

As soon as the Shenzhen-Zhongshan Link had opened, it welcomed a lot of traffic. In the first month of its opening, the number of trains exceeded 3 million.

As the only direct highway connecting the "Shenzhen-Dongguan-Huizhou Expressway" on the east bank of the Zhuhai and the "Zhuhai-Zhongshan-Jiangmen" on the west bank, the opening of the Shenzhen-Zhongshan Link has not only realized the "hard connection" between land and shipping, but also promoted a "soft connection" between economy and industry.

The Shenzhen-Zhongshan Bridge

The major features of the Shenzhen-Zhongshan Link are the Shenzhen-Zhongshan Bridge, West Artificial Island and the Subsea Tunnel. Among them, the Shenzhen-Zhongshan Bridge, which was constructed with the participation of China Communications Construction Company’s Second Harbor Engineering Company, was one of the major elements of the link.

The bridge has set five world records, including for the world's largest span all offshore steel box girder suspension bridge, the world's highest navigable clear sea bridge, and the world's largest sea anchorage.

The construction of the bridge was full of challenges, with the team working hard to ensure the steady progress of the project, with a spirit of hard work and attention to detail.

In order to reduce the labor intensity of workers, lower the risk of high-altitude operations, and improve work efficiency, the project team developed the first integrated intelligent tower crane in China. The tower column construction speed can reach 1.2 meters per day, which is nearly 50 percent more efficient than traditional processes. At the same time, it reduces the number of high-altitude operators by nearly 60 percent.

In April, the Shenzhen-Zhongshan Bridge won the "Nobel Prize" in the bridge industry - the "George S. Richardson" awarded by the International Bridge Conference, demonstrating the industry's recognition of the excellent internal and external quality of the Shenzhen-Zhongshan Link.
