The Edong Bridge (Chinese鄂东 长江 大桥) is a cable-stayed bridge that leads into the Chinese province of Hubei on the Yangtze River. The bridge completed in 2010, is located about 80 km southeast of Wuhan north Huangshi City and performs three highways across the river. It counts with a span of 926 m to the cable-stayed bridge with the largest span in the world. The entire newly constructed road section is 6203 m long, of which the cable-stayed bridge measures 1488 m. The pylons in the form of an inverted Ypsilon is 242.5 meters high.

The bridge girder of cable-stayed bridge consists of nine fields. The field between the pylons is made of two parallel steel girders, which are covered with an orthotropic plate. By omitting the lower base plate weight could be saved without the dynamic or aerodynamic property causing too much impact. The construction height is 3.45 m.

The leading of the pylons against the country fields use Stahlholkästen. However, they are covered by a concrete slab, in contrast to the mean field.

The construction of the bridge took place in the cantilever. The nearly 400 -ton segments of the middle panel were delivered on the water and raised to the assembly by means of gantry cranes strandjack to the height of the bridge girder. The cranes used already in the Sutong Bridge came on one side for use.
