China Opens World’s Longest Sea Bridge and Tunnel

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.

At the opening ceremony, Han Zheng, the top Chinese official proclaimed that the bridge marked the first time that Hong Kong, Macau and the mainland had jointly cooperated on a major infrastructure project.

By 2030, authorities expect 29,100 vehicles and 126,000 passenger trips to criss-cross the bridge daily. Goods manufactured on the western end of the Pearl River Delta can now reach the container port and international airport of Hong Kong in 45 minutes, and a tourist landing in Hong Kong International Airport now has another option to reach Macau instead of taking a ferry.

All of the vehicles that will be allowed on the bridge, including trucks, tour buses, shuttles and select private cars, will require permits from all three jurisdictions. All three jurisdictions will also require passengers to clear immigration and customs.

Strict quotas will be enforced for private cars. Only 10,000 Hong Kong cars belonging to people or businesses that fit certain criteria will be issued a license to enter the mainland, and vehicles will require a separate cross-border Chinese license plate. Only 300 Hong Kong cars can enter Macau, and 600 Macau-licensed cars can drive to Hong Kong.

There is no public transportation running between the cities so private tour bus companies will run a shuttle bus between immigration points on either end of the bridge and licensed cross-border tour buses that can travel to the center of Hong Kong and Zhuhai.

One such cross-border operator called Trans-Island Limousine told ABC News on Tuesday morning that it is starting a slow roll out of bus lines this week. A one-way ticket will cost the equivalent of $15 and a round-trip ticket will cost about $28.
