The Great Bridge Danyang - Kunshan (Chinese丹阳-昆山 大桥, Pinyin Danyang - Kunshan Da Qiao ) is a 164.8 km long viaduct of the high-speed Beijing- Shanghai. The mostly built of prefabricated bridge is the longest bridge in the world.

The bridge is located between Shanghai and Nanjing in the east of China, in the province of Jiangsu. She leads the high-speed line as elevated route mostly over land, except in Suzhou, where it crosses parts of the Yangcheng Lake. On the bridge there are the stations north of Danyang, Changzhou North, East Wuxi, Suzhou and Kunshan North South.

The bridge consists of 32 -meter-long hollow box girders and some longer components, which were used to bridge roads, railway lines or waters. The box girders were created in four production plants along the track, brought to the already constructed bridge part to the installation site and placed there by a special crane on the pier. Each production plant went temporarily more than two carrier finalized per day.

The construction took four years, during which at times over ten thousand employees were working on the site. The first of over two thousand pillars were cast on April 7, 2008. On 24 May 2009 the last box girder was used. The track laying work had been completed on November 6, 2010 and the operation on the high speed line was opened on 30 June 2011. The construction costs amounted to 8.5 billion U.S. dollars.
