The Great Bridge of Tianjin (Chinese天津 特 大桥) is a 113.7 km long viaduct of the high-speed Beijing- Shanghai and is currently the second longest bridge in the world.

The bridge is located between Langfang and Qingzhou ( Qing ) in the east of China in Hebei Province. She leads the elevated route of the high-speed line across the open country and whose station is also located on this bridge through the western suburbs of Tianjin named Tianjin South.

The design of the elevated road has, on the one hand to avoid numerous individual buildings for crossing roads and railway lines and on the other hand to shorten the construction period. In addition, the railway line in this type of construction requires less land area: an embankment required per line kilometer 28.4 hectares, the bridge but only 10.9 ha, less than half the area.

The bridge consists of 32 m long hollow box girders, each of 860 tons. These carriers have been created in two work bays along the bridge, placed on the already built bridge part to the installation site and placed there by a special crane on the pier.
