The construction of the Hong Kong-Zhuhai-Macao Bridge is a large cross-sea channel connecting Hong Kong, Zhuhai and Macao. It is the longest cross-sea bridge in the world with a total length of 55 km includes the bridge, island and tunnel. The submerged tunnel of bridge, is the longest mileage, the largest investment and the most difficult construction in the history of China.
Hong Kong-Zhuhai-Macao Bridge will become the world's longest cross-sea bridge. As the longest mileage, the largest investment and the most difficult construction of the cross-sea bridge project in the history of China. Hong Kong-Zhuhai-Macao Bridge is widespread concerned by domestic and foreign. Hong Kong-Zhuhai-Macao Bridge across the Lingdingyang bay, east to Hong Kong, west to Zhuhai and Macao, is under the "one country, two systems" framework to build large-scale cross-sea traffic engineering for the first time in Guangdong, Hong Kong and Macao, Hong Kong-Zhuhai-Macao Bridge will connect the world's most dynamic Economic Zone and the establish far-reaching significance by building rapid access to three economics and social integration of Hong Kong, Macao and Zhuhai.
