Hong Kong-Zhuhai-Macao Bridge

The Hong Kong–Zhuhai–Macau Bridge is a 55-kilometre bridge–tunnel system consisting of a series of three cable-stayed bridges, an undersea tunnel, and four artificial islands. It is both the longest sea crossing and the longest open-sea fixed link in the world. The HZMB spans the Lingding and Jiuzhou channels, connecting Hong Kong, Macau, and Zhuhai—three major cities on the Pearl River Delta in China.

The HZM Bridge was designed to last for 120 years and cost ¥127 billion to build. The cost of constructing the Main Bridge was estimated at ¥51.1 billion funded by bank loans and shared among the governments of mainland China, Hong Kong and Macau.Originally set to be opened to traffic in late 2016, the structure was completed on 6 February 2018 and journalists were subsequently taken for a ride over the bridge. On 24 October 2018, the HZMB was opened to the public after its inauguration a day earlier by Chinese leader Xi Jinping.
