China recently opened the Shenzhen-Zhongshan Link in Guangdong. The 24-kilometer passage consists of one underwater tunnel, two bridges and two artificial islands, making it one of the most difficult cross-sea cluster projects in the world. It also holds 10 world records.
Check out Shenzhen-Zhongshan Link’s 10 world records:
The Shenzhen-Zhongshan Bridge
- The world’s longest span fully offshore steel box girder suspension bridge (main span of 1666 meters).
- The world’s highest bridge deck and highest navigation clearance for a sea bridge (bridge deck height of 91 meters).
- The world’s largest offshore suspension bridge anchor (single anchor’s concrete volume of approximately 344,000 cubic meters).
- The world’s highest wind resistance test speed for a suspension bridge (maximum flutter test wind speed of 83.7 m/s).
- The world’s largest steel bridge deck hot-mix epoxy asphalt paving (area of 378,800 square meters).
The Shenzhen-Zhongshan Tunnel
- The world’s longest two-way eight-lane immersed tube tunnel (length of 5,035 meters, consisting of 32 tube sections + one final joint).
- The world’s widest underwater steel shell-concrete immersed tube tunnel [standard tube section length of 165 meters, width of 46 meters (widest of 55.6 meters), height of 10.6 meters].
- The world’s largest single-volume cast for a steel-shell immersed tube using self-compacting concrete (single tube section concrete volume reaching 29,000 cubic meters, totaling 910,000 cubic meters).
- The world’s first underwater expressway interchange – airport interchange.
10. The world’s widest (three-meter) repeatedly foldable M-shaped water stop used in the final joint of an immersed tube tunnel.
