Description:

The Nanpu Bridge is the longest cabled-stayed bridge in the world with an overall span of 8,346 m. The main bridge is 846 m (925 yards) and the total length of the elevated circular approaches is 7500 m (8,202 yards) with 423 m (462 yards) for the span. With a bridge height of 46 m (50 yards) over the water, ships of up to 55 thousand tons are able to successfully navigate below the bridge.

The main bridge is a cable-stayed bridge with two main towers and double cable planes. The towers stand on each bank and are built of reinforced concrete, 150 m (492 feet) high, and resembling the letter ‘H’. Each side of the bridge has 22 pairs of steel cable linking the girder cable plane, which look like 2 fans from a distance.

The main bridge is a composite structure of steel and concrete. The lower layer of the bridge deck is made of a large 'beam' frame while the upper layer is reinforced with concrete. The steel deck and the bridge surface were welded with electronic welding, and concrete was poured into the junction.
