The first major combined bridge and tunnel sea-crossing project in China is the Hong Kong-Zhuhai-Macau Bridge project. Consisting of three cable-stayed bridges and one 6-km sea crossing tunnel, it will have a total length of 55 km. It will be the world’s longest sea bridge and will link three cities in China's Pearl River Delta — creating one mega-city of 42 million people and slashing travel time between Hong Kong and Chinese city Zhuhai from three hours to just 30 minutes.
