World's longest sea bridge constructed in China

Setting a world record, China has successfully completed the construction of the world's longest sea bridge. The bridge is said to link Hong Kong, Zhuhai and Macao, spanning a 6-year pre-construction planning and an additional 8-year on-site construction.

Overall, the length of the bridge is set at 55 kilometers. Major work on the bridge consisted of a 22.9-kilometre-long main bridge, a 6.7-kilometre-long tunnel and an artificial island off the bridge, which is considered the most technically demanding part of the whole construction.

In the next few weeks, engineers and constructors will test the coordination of the bridge’s various systems and equipment, and proceed with inspection and cleaning work, said Zhang Jinwen, project director with the Hong Kong-Zhuhai-Macao Bridge (HZMB) Authority.

“The bridge will be put into trial operation after its port project is completed and taken over by customs, inspection and quarantine, and border control authorities,” Zhang said.

“We have a whole toolbox of policies at our disposal,” Su said. “It is like playing cards. We can adjust our moves accordingly.”

The bridge will slash travel time between Hong Kong and Zhuhai from three hours to just 30 minutes, further integrating cities in the Pearl River Delta.
