In pics: construction site of Hong Kong-Zhuhai-Macao Bridge

Photo taken on March 26, 2017 shows the construction site of the Hong Kong-Zhuhai-Macao Bridge in the Lingdingyang waters, south China. The Hong Kong-Zhuhai-Macao Bridge is to be officially open to traffic at 9 a.m. on Oct. 24. The 55-kilometer-long bridge, situated in the Lingdingyang waters of the Pearl River Estuary, will be the world's longest sea bridge. The construction began on Dec. 15, 2009. It will slash the travel time between Hong Kong and Zhuhai from three hours to just 30 minutes, further integrating the cities in the Pearl River Delta. (Xinhua)
