The Danyang – Kunshan Great Bridge ( Chinese 丹昆特 大橋 / 丹昆特 大桥 , Pinyin Dānyáng-Kūnshān dà qiáo ) is a 164.8 km long railway viaduct on the Beijing – Shanghai high-speed line . The bridge, mostly made of prefabricated parts , is the longest bridge in the world.
history
The high-speed line was laid on a bridge in order to use less land in the densely populated area and to shorten the construction time of the line. In contrast to a ground-based railway line, the bridge only requires 10.9 hectares of land per kilometer instead of 28.4 hectares. The use of standardized prefabricated parts reduces the planning effort and enables efficient production.
The construction time was four years, with over ten thousand employees at times working on the construction site. The first of the more than two thousand pillars were poured on April 7, 2008. The hollow box girders were created in four production plants along the route, brought to the installation site on the already built bridge section and there placed on the pillars by a special crane. At times, each production facility completed more than two beams per day. The last box girder was installed on May 24, 2009. The track-laying work was completed on November 6, 2010 and operations on the high-speed line began on June 30, 2011. The construction costs amounted to 8.5 billion US dollars .
Building
The bridge is located between Shanghai and Nanjing in the east of China, in Jiangsu Province . It leads the high-speed route as an elevated route mostly overland, except near Suzhou , where it crosses parts of Yangcheng Lake . The Danyang North , Changzhou North , Wuxi East , Suzhou North and Kunshan South stations are located on the bridge . The bridge consists of 32 meter long hollow box girders and some longer components that were used to bridge roads, railway lines or bodies of water.
