Since its opening, the Shenzhen-Zhongshan Link has played a pivotal role in shaping a one-hour commuter circle between Shenzhen and Zhongshan, greatly accelerating economic integration within the Guangdong-Hong Kong-Macao Greater Bay Area.

Over the past year, the total traffic volume has exceeded 31 million vehicles, with a daily average of 86,000. The cross-city shuttle bus service sees an average of 6,000 passengers transported each day.

Stretching 24 kilometers with a design speed of 100 km/h, the Link was developed with the full involvement of CCCC, which was responsible for key components including the west artificial island, immersed tunnels, Shenzhen-Zhongshan Bridge, Zhongshan Bridge, and non-navigable bridges.

Over the course of more than seven years, CCCC developed a world-leading suite of equipment and technologies for cross-sea infrastructure construction. The project set over 20 world records, including the highest navigational clearance for a sea bridge and the world's first bi-directional, eight-lane steel-shell immersed tunnel. It secured more than 170 patents, filled numerous gaps in the industry, and marked a major leap forward in the intelligent construction of cross-sea corridors.
