The Beijing–Shanghai High-Speed Railway includes a 164.8 km viaduct called the Danyang-Kunshan Grand Bridge.[1] Since 2011, this structure has been recognized by Guinness World Records as the world's longest bridge across all categories.[1][2]
Geography and history
The bridge runs through Jiangsu province between Shanghai and Nanjing.[3] It is a cable-stayed bridge with two main sections: the Danyang section (52.4 km) and the Kunshan section (112.4 km).[4] The structure has a clearance of 150 meters to allow ships to pass underneath.[4] The bridge's route lies about 5 to 50 miles south of the Yangtze River, running in a roughly parallel direction.[3]
Traveling from west to east, the bridge goes past the northern edges of Danyang, Changzhou, Wuxi, Suzhou, and finally Kunshan.[3] The project required 10,000 workers, spanned four years, and had an approximate cost of $8.5 billion.[2]
What the cited sources add
The same source reports that travel time between the two cities dropped from about four hours to just over one hour.[4] According to Benson, official figures show 5.6 miles of the bridge stretch over Yangcheng Lake, supported by 2000 pillars and steel cables.[4] The article adds that the bridge is about 100 feet above the ground with a span of 260 feet.[4] Benson describes the bridge as designed to withstand earthquakes, typhoons, and other natural disasters, with an expected lifespan over 100 years.[4]
