The 34.2-mile bridge and tunnel that have been almost a decade in the making for the first time connect the semi-autonomous cities of Hong Kong and Macau to the mainland Chinese city of Zhuhai by road.
The Hong Kong-Zhuhai-Macau Bridge spans the mouth of the Pearl River and significantly cuts the commuting time between the three cities. The previously four-hour drive between Zhuhai and Hong Kong will now take 45 minutes.
One section of the crossing dives underwater into a 4.2 mile tunnel that creates a channel above for large cargo ship containers to pass through.
The project came in over budget with Hong Kong alone investing $15 billion in it — and delayed, as it was originally slate to open in 2016.
At the opening ceremony, Han Zheng, the top Chinese official who oversees Beijing’s at-times tense relationship with Hong Kong, proclaimed that the bridge marked the first time that Hong Kong, Macau and the mainland had jointly cooperated on a major infrastructure project.
