The Hong Kong–Zhuhai–Macau Bridge (HZMB) is a 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 (US$18.8 billion) to build. The cost of constructing the Main Bridge was estimated at ¥51.1 billion (US$7.56 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. Planning Background Hopewell Holdings founder and then-managing director Gordon Wu proposed the concept of a bridge-tunnel linking China, Hong Kong and Macau in the 1980s. Wu stated that he got the idea in 1983 from the Chesapeake Bay Bridge–Tunnel. In 1988, Wu pitched the concept to Guangdong and Beijing officials. He envisaged a link farther north than the current design, beginning at Black Point near Tuen Mun, Hong Kong and crossing the Pearl River estuary via Neilingding Island and Qi'ao Island. His proposed bridge would have ended at the Chinese village of Tangjia, and a new road would have continued south through Zhuhai before terminating at Macau. Discussions stalled after the Tiananmen Square protests in mid-1989 "unnerved" Wu and other foreign investors, and caused Hopewell's Hong Kong share prices to plunge. The route proposed by Wu was promoted by the Zhuhai government under the name Lingdingyang Bridge. In the mid-1990s, Zhuhai built a bridge between the Zhuhai mainland and Qi'ao Island that was intended as the first phase of this route, though the full scheme had not been approved by either the Chinese or Hong Kong governments at the time. China's central government showed support for this project on 30 December 1997. The new Hong Kong government was reluctant, stating that it was still awaiting cross-border traffic study results, and Hong Kong media questioned the environmental impact of the project with regard to air pollution, traffic and marine
