The Hong Kong-Zhuhai-Macao Bridge, the world's longest sea crossing bridge, was opened to traffic in Zhuhai on 23 October 2018. President Xi Jinping announced the official opening of the bridge. China Communications Construction Group (CCCG) constructed the majority of the immersed tube tunnel, the east and west artificial islands, the Qingzhou navigation channel bridge, the artificial islands at the port, and the Hong Kong and Macau sections, accounting for over 70% of the main works. The bridge was named one of the 'New Seven Wonders of the World' by The Guardian. During the construction of the immersed tube tunnel, CCCG builders have completed more than 100 experimental studies, developed more than 10 world-leading special equipment and systems, obtained more than 500 patents, and overcome more than 10 world-class engineering problems in the installation of offshore immersed tubes. The Hong Kong-Zhuhai-Macao Bridge uses the equivalent of 60 Eiffel Towers in steel alone and is capable of resisting earthquakes of magnitude 8 and typhoons of over 16.
