Dingshan Bridge, Cable-stayed road-rail bridge over the Yangtze in Chongqing, China

Dingshan Bridge is a cable-stayed and road-rail bridge that crosses the Yangtze River in Chongqing, connecting Jiangjin and Jiulongpo. The structure features tall towers from which cables fan out to support the roadway, with six lanes for vehicle traffic on the upper deck and the Chongqing Rail Transit Line 5 running beneath it.

The bridge opened in 2013 as a result of complex construction over the Yangtze River. The project was part of rapid infrastructure growth in Chongqing and improved connections between districts that previously required longer travel times.

The bridge's name was chosen through a public naming campaign: it was originally called Fenfangwan Yangtze River Bridge and Jiangjin Yingbin Yangtze River Bridge, and in April 2013 the local government settled on Dingshan. Its lower deck was built with a reserved channel for what was planned as Chongqing Rail Transit Line 5, so the structure was prepared for rail from the start.

The bridge carries six lanes of China National Highway 212 on its upper deck, with a reserved channel for Chongqing Rail Transit Line 5 below; the rail line was originally planned as Line 5. The deck runs between Dingshan Subdistrict in Jiangjin District and Xipeng Town in Jiulongpo District. The main span measures 464 metres within a 896-metre main bridge.

The bridge's name was chosen by public contest: it was originally called Fenfangwan Yangtze River Bridge and Jiangjin Yingbin Yangtze River Bridge before the government settled on Dingshan in April 2013. Its two towers rise 188.3 metres, built with a curved profile and a stiffened steel frame.
