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 (518m across) 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.
This image shows about half of the total span (looking from east to west) of the bridge.
The pontoon section you see here can be removed to allow river traffic (mostly barges hauling sand) to pass through.
