Shenzhen–Zhongshan Bridge

The Shenzhen–Zhongshan Bridge is a bridge under construction. It will 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 2024 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 estuary, and some 32 km north of the new Hong Kong–Zhuhai–Macau Bridge, which links the cities of Hong Kong, Zhuhai, and Macau at the southern end of the PRD. Construction started in May 2017.

The project will consist of a 6.7 km tunnel starting on the Shenzhen side, and 19 bridges totalling 43 km. Construction started in late 2016 and opening is scheduled for 2024. There will be four lanes in each direction, with a maximum speed of 100 km/h. The bridge will join the Guangshen Expressway to the south of Shenzhen airport and the Jihe Expressway to the east of the airport on the eastern side of the delta with the Zhongjiang Expressway on the western side. It will cut travel time from Shenzhen to Zhongshan to less than 30 minutes. Analysts from mainland China and Hong Kong found the project might draw as much as 40 percent of the potential traffic away from the Hong Kong–Zhuhai–Macau Bridge and reduce the regional dominance of Hong Kong's airport and harbour.^[5]
