After seven years of construction, the world-class sea-crossing cluster project, the Shenzhen-Zhongshan link, has been completed, setting ten world records.
It boasts the world's largest span for a fully offshore steel box girder suspension bridge, with a main span of 1,666 meters.
It features the highest bridge deck and the highest navigable clearance for a sea bridge, with the deck standing at 91 meters above water.
The project includes the world's largest offshore suspension bridge anchor, with a single anchor containing approximately 344,000 cubic meters of concrete.
It has been tested against the world’s highest wind resistance for suspension bridges, withstanding a flutter test wind speed of 83.7 m/s.
The bridge’s steel deck is covered with the world’s largest volume of hot-mix epoxy asphalt, spanning an area of 378,800 square meters.
It features the world's longest two-way eight-lane undersea immersed tube tunnel, measuring 5,035 meters in length, consisting of 32 tube sections plus one final joint.
The undersea steel shell-concrete immersed tube tunnel is the world’s widest, with standard tube sections measuring 165 meters in length, 46 meters in width (widening to 55.6 meters), and 10.6 meters in height.
The project has seen the world’s largest single-volume pour of self-compacting concrete for a steel shell immersed tube, with a single tube section involving 29,000 cubic meters of concrete, accumulating to a total of 910,000 cubic meters.
It is the first underwater highway interchange & airport interchange in the world.
The project utilizes the world's widest (3 meters) repeatedly foldable M-shaped waterstop in the final joint of the immersed tube.
