The Hong Kong–Zhuhai–Macau Bridge (HKZMB) is a Bridge–tunnel system, which consists of a series of three cable-stayed bridges and one undersea tunnel, as well as 3 artificial islands, spanning the Lingdingyang channel, that connects Hong Kong with Macau and Zhuhai, three major cities on the Pearl River Deltain China. The 55-kilometre (34 mi) link is expected to cost 110 billion yuan ($15.9 billion). It is among the longest fixed-links in the world and is a major landmark in the area. Originally set to be opened to traffic in October 2016, the structure was completed during November 2017 and is planned to open to vehicular traffic in July 2018.
