The Nanpu Bridge (Chinese南浦 大桥/南浦 大桥, Pinyin Nánpǔ Daqiao ) is a cable-stayed bridge over the Huangpu River in Shanghai, China. With 432 meter span, she was the first cable-stayed bridge with a span of over 400 meters in China. She is among the hundreds of cable-stayed bridges with the largest span in the world.

The bridge carries seven lanes of a highway - three leading westward and eastward leading four, and is responsible for 4.5 to 5 million car trips a day designed. There are sidewalks that can be achieved with a non-free lift and serve as a viewing platform on both sides. The Nanpu Bridge, together with the Yangpu Bridge one of the major road connections between the downtown Puxi and Pudong district east of the Huangpu River. Both bridges are part of the Inner Ring Road of Shanghai.

The cable-stayed bridge was designed by the engineering firm the city of Shanghai and the Institute for Urban Design at the University of Shanghai with the support of Holger S. Svensson from the engineering firm of Fritz Leonhardt. For the first time improved techniques for the efficient production of cable anchoring and cable sheathing were applied. A special focus of the aerodynamic design of the bridge has been paid, which flutter a bridge at high wind speeds to prevent. Construction began on 15 December 1988 ended with the opening on 1 December 1991. The construction costs amounted to 814.7 million yen.

The main bridge has five openings, with posts spaced 76.5 m 94.5 m 423 m 94.5 m 76.5 m. The 150 m high pylons carry the 30.35 m wide bridge girders in steel composite construction at a height of 46 m above the water level, so that 50,000 -ton ships to pass under the bridge. It consists of two I-shaped with longitudinal support, on which prefabricated concrete plates are fixed, the connected after hanging up with by a concrete cast on site with the head bolts of steel structure.

The bridge girder is supported by two cable planes, which are anchored to the H-shaped pylons of reinforced concrete. On each side of pylon there are 22 pairs of cables, which are arranged in a fan shape.

On the Puxi side, an elaborate spiral ramp connects, in which links the motorway triangle with Zhongshan South Road. On the Pudong side, a nearly seven -kilometer access road connects to, which includes the interchange with the Longyang Road and ends in Zhangjiang motorway junction.
