The Edong Bridge ( Chinese 鄂东 长江 大桥 ) is a cable-stayed bridge that spans the Yangtze River in the Chinese province of Hubei . The bridge, completed in 2010, is located approximately 80 km southeast of Wuhan north of the city of Huangshi and runs three highways over the river. With a span of 926 m, it is one of the cable-stayed bridges with the largest spans in the world . The entire newly built road section is 6,203 m long, of which the cable-stayed bridge measures 1,488 m. The inverted Y- shaped pylons are 242.5 meters high.
The bridge girder of the cable-stayed bridge consists of nine fields. The field between the pylons is formed by two parallel steel box girders, which are covered with an orthotropic deck . By omitting the lower base plate, weight could be saved without impairing the dynamic or aerodynamic properties too much. The construction height is 3.45 m.
The fields leading from the pylons towards the land also use steel boxes. In contrast to the central field, they are covered by a concrete slab.
The bridge was built using a cantilever . The almost 400-tonne segments of the middle field were delivered on the water and lifted to the level of the bridge girder for assembly by gantry cranes using strand jacks . The construction cranes already used on the Sutong Bridge were used on one side.
