Xihoumen Bridge 2009
The Bridge
South of Shanghai is a group of islands in the East China Sea connected to the mainland by a series of five bridges in a 46km crossing. The main island is Zhoushan and the largest crossing is the Xihoumen Bridge.
It has a central span of 1,650m, one of the world’s longest, and has a twin-box deck design, pioneered by Bill Brown in the 1990s. The deck has the two streamlined-box girders connected by cross-diaphragms to achieve aerodynamic stability for such a long span.
The northern tower is sited on a small rocky outcrop and has a 578m suspended side span to the island of Cezi. The south tower is on the Jintang Island with a self-supporting (viaduct) side span.
