Danyang–Kunshan Grand Bridge — Local services in Suzhou City

The Danyang–Kunshan Grand Bridge is a 164.8-kilometre-long (102.4 mi) viaduct on the Beijing–Shanghai High-Speed Railway. It is the longest bridge in the world ( still in 2022).

The bridge is located on the rail line between Shanghai and Nanjing in Jiangsu province. It is in the Yangtze River Delta where the geography is characterised by lowland rice paddies, canals, rivers, and lakes. The bridge runs roughly parallel to the Yangtze River, about 8 to 80 km (5 to 50 mi) south of the river. It passes through the northern edges of population centers (from west to east) beginning in Danyang, Changzhou, Wuxi, Suzhou, and ending in Kunshan. There is a 9-kilometre long (5.6 mi) section over open water across Yangcheng Lake in Suzhou.

Through five rounds of "Speed-Up" campaigns in April 1997, October 1998, October 2000, November 2001, and April 2004, passenger service on 7,700 km (4,800 mi) of existing tracks was upgraded to reach sub-high speeds of...
