The Nanpu Bridge ( Chinese 南浦 大橋 / 南浦 大桥 , Pinyin Nánpǔ Dàqiáo ) is a cable-stayed bridge over the Huangpu River in Shanghai , China . With a span of 432 meters, it was the first cable-stayed bridge with a span of over 400 m in China. It is one of the hundred cable-stayed bridges with the largest spans in the world.
The bridge spans seven lanes of a motorway - three westward and four eastward, and is designed for 4.5 to 5 million car journeys per day. There are sidewalks on both sides , which can be reached with a payable lift and which serve as a viewing platform . The Nanpu Bridge, together with the Yangpu Bridge, is one of the most important road links between downtown Puxi and the Pudong district east of the Huangpu River. Both bridges are part of Shanghai's Inner Ring Road .
The cable-stayed bridge was designed by the engineering office of the city of Shanghai and the Institute for Urban Development at the University of Shanghai with the support of Holger S. Svensson from the engineering office of Fritz Leonhardt . For the first time, improved techniques were used for the efficient production of the rope anchoring and the rope sheathing. Particular attention was paid to the aerodynamic design of the bridge, which should prevent the bridge from fluttering at high wind speeds. Construction began on 15 December 1988 and finished with the opening on 1 December 1991. The construction costs amounted to 814,700,000 ¥ .
The main bridge has five openings with the pillar spacing 76.5 m + 94.5 m + 423 m + 94.5 m + 76.5 m. The 150 m high pylons support the 30.35 m wide steel composite bridge girder at a height of 46 m above the water level, so that 50,000-ton ships can pass under the bridge. It consists of two I-shaped beams with longitudinal beams on which prefabricated concrete slabs are attached, which are connected to the head bolts of the steel structure by a concrete casting on site .
The bridge girder is supported by two levels of cables that are anchored to the H-shaped pylons made of reinforced concrete . On each side of a pylon there are 22 pairs of cables arranged in a fan shape.
On the Puxi side, there is an elaborate, spiral-shaped driveway ramp, which connects the motorway triangle with Zhongshan South Road. On the Pudong side there is an almost seven kilometer long driveway, which includes the interchange with Longyang Road and ends at the Zhangjiang interchange.
