On the morning of November 28th, around 10 AM, a core project of the Guangdong-Hong Kong-Macao Greater Bay Area, the Shenzhen-Zhongshan Link’s underwater tunnels were connected, signifying the completion of the Shenzhen-Zhongshan Link.
The link spans 24 kilometers with four lanes in each direction, designed for a speed of 100 kilometers per hour. As a world-class trans-sea cluster project integrating “bridge, island, tunnel, and underwater interchange,” it presents one of the most challenging trans-sea cluster projects globally. The underwater tunnel, about 6.8 kilometers long, is the world’s longest and widest steel-shell concrete immersed tunnel.
This year, the link achieved three major construction milestones: in April, the world's largest offshore steel box girder suspension bridge, Lingdingyang Bridge, with a main span of 1666 meters, was connected; in June, the world's first multiple-arch immersed tunnels with eight traffic lanes made of steel-shell concrete was linked; also in June, the main structure of the first underwater interchange on a highway, located on the artificial island in the east, was completed. Additionally, the main tunnels of the link have been connected.
The Shenzhen-Zhongshan Link will be open to the public in June 2024. At that time, the travel time from Zhongshan to Shenzhen will be reduced from the current approximately two hours to less than 30 minutes.
