The Hong Kong-Zhuhai-Macao Bridge is a bridge-tunnel system linking Hong Kong, Zhuhai, and Macao in China. The construction started in 2009. In 2018, the bridge opened to the public and became the southern section of the Ring Expressway in the Pearl River Delta region. Starting from the Hong Kong Port artificial island near Hong Kong International Airport, the HZMB spans the waters of the Lingdingyang channel of the South China Sea and connects to Zhuhai and Macao artificial islands, ending at the Hongwan Interchange in Zhuhai. The total length of the HZMB is 55km (34m), including the 29.6km (18m) Main Bridge. As the longest sea crossing bridge in the world, the HZMB is remarkable for its long mileage, high investment and difficulty in building in China's construction history.
The Sail twin towers are located at the Jiuzhou Channel Bridge on the Hong Kong-Zhuhai-Macao Bridge. The shape of the twin towers is based on the sails on a vessel, which means “sailing and sailing”.
The Triple Dolphin Tower is located on the direct arrival channel bridge of the Hong Kong-Zhuhai-Macao Bridge. White dolphins are the first-class protected animals in China whose habitat lies in the water area below the tower. The Dolphin Tower formed in the shape of white dolphins symbolizes the harmonious coexistence of human beings and nature.
Qingzhou Channel Bridge is a double-tower, double cable plane steel box girder cable-stayed bridge, which has the longest main span among the whole viaduct section. The structure of the tower refers to the "Chinese knot" element thus "curves" the original right-angle and the modeling of right-angled. The whole tower looks slim, elegant and delicate.
The east and west artificial Islands built at the Zhu-Macao Port are two of largest artificial islands in the Hong Kong-Zhuhai-Macao Bridge project. The two artificial islands have the same overall structure, including main buildings, squares, and round-the-island roads. However, the functions of the two islands are different. The East Island functions as an observation deck while the West Island functions as a working place for the maintenance service of the bridge. The east artificial island, adjacent to Hong Kong's Lantau Island and Hong Kong International Airport, offers a close-up view of the gliding flight with the lush mountain scenery of Lantau. To the south is the boundless seaand the nature reserve of the Chinese white dolphins. Occasionally, you can see the white dolphins play and float up and down in the water. In between the two islands, the voyages and the waves of the clouds are on the shore with the urban scenery of Zhuhai high-rise buildings in the north forming a vast seascape. Between the two islands, a vast ocean scene is formed by the sea-going ships, the rising water vapor brought about by the tide rushing in, and the city scenery with high-rise buildings on the north side of Zhuhai.
