First constructed in the 12th century during the Southern Song Dynasty, the Xiang Zi Bridge (also known as the Guang Ji Bridge) spans the Han River in Chaozhou, southeastern Guangdong province.
The bridge has been rebuilt several times, and is currently a combination of 24 piers and a pontoon section near the centre that opens for river traffic to pass through. This particular photo shows three of the piers. Today, the only traffic the bridge sees are pedestrians, mostly tourists (I don't think anyone uses the bridge simply to cross the river, as you need to pay to get onto it).
The bridge was recently reconstructed and opened again in early 2008. It has a span of 518 metres, and is really a very unique piece of architecture.
I have plenty of photos of this lovely bridge that I'll upload in the near future.
