Shenzhen–Zhongshan Bridge The Shenzhen–Zhongshan Bridge is a planned construction project to connect two major cities on the Pearl River Delta (PRD) in China: the city of Shenzhen on the eastern side of the PRD, and the city of Zhongshan on the western side. It will consist of a series of bridges and tunnels, starting from Bao'an International Airport on the Shenzhen side. The proposed 51 km eight-lane link is scheduled to be completed in 2021 and is expected to cost around US$4.83 billion. It will be located about 27 km downriver from the Humen Bridge, the only current bridge crossing of the delta, and some 32 km north of the new Hong Kong–Zhuhai–Macau Bridge, which is currently under construction and will link the cities of Hong Kong, Zhuhai, and Macau at the southern end of the PRD, scheduled for completion in 2016.
