China opens world’s longest sea bridge and tunnel to connect Hong Kong and Macau to the mainland

Chinese President Xi Jinping inaugurated China’s latest mega-infrastructure project on Tuesday: The world’s longest sea crossing.

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.

Such a bridge may not be practical, but it would be fun, and no doubt become something of a tourist attraction in a city already blessed with an abundance of tourist attractions. Such a bridge exists, at least in the form of a concept design by Paris-based architectural studio Atelier Zündel Cristea. (Pics)
