Amazing World’s Longest Bridge (2023)
The Danyang-Kunshan Grand Bridge, on the Beijing-Shanghai high-speed railway in China, is the world’s longest bridge. It covers a total distance of 164,800 meters, which is around 102.4 miles. 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 characterized 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, and Suzhou, and ending in Kunshan. There is a 9-kilometre long (5.6 mi) section over open water across Yangcheng Lake in Suzhou.
The construction of the Danyang-Kunshan Grand Bridge was completed in 2010 and opened in 2011. A robust team of 10,000 men, including core laborers, engineers and rest professionals, worked tirelessly and dedicatedly to ensure that the construction of the world’s longest bridge in Asia could complete in the stipulated time frame. As of June 2011, Danyang-Kunshan Grand Bridge in China held the Guinness World Record for being the world’s longest bridge.
The China Road and Bridge Corporation (CRBC), a subsidiary of China Communications Construction Company designed and built the bridge. It is a Chinese government-funded company which was originally part of the Foreign Aid Office of the Ministry of Communications of China. This company leads major civil engineering projects in China like highways, railways, bridges, ports, and tunnels.
