The 55km (34 mile) Hong Kong-Zhuhai-Macau Bridge, the world’s longest sea crossing, opened to the public in late October, 2018. The new and historic connection is essentially a bridge–tunnel system consisting of a series of three cable-stayed bridges, an undersea tunnel, and four artificial islands. Designed to last for 120 years, it is both the longest sea crossing and the longest fixed link on earth. The new mega bridge is a showpiece of innovation and integration between Hong Kong and mainland China.
Travel times from Hong Kong to Macau and Zhuhai have been halved, promoting regional tourism, shortening commute time and fostering closer ties within the Pearl River Delta, which includes major cities such as Guangzhou and Shenzhen.
