With only one third of its full height visible, the Wujiang Bridge crossing in Yuqing County might not appear very high but looks can be deceiving. Just 15 kilometers downstream of the bridge is the Goupitan Dam which created a massive reservoir nearly 200 meters deep. At the bridge site the water is more then 150 meters deep. The G69 Dao'an Expressway has one of the greatest collections of high bridges in the world.

The Wujiang Yuqing cable stayed bridge has 172 meter tall H-frame towers that support a span configuration of 125+360+125 meters. The relatively small back spans of 125 meters coupled with no approach spans reveal just how steep the slopes are between the banks. The concrete deck has a full width of 28 meters and a depth at the center span of 3.16 meters. There are 112 cable stays with a distance between stays of 12 meters for the main span and a distance of 8 meters on the side spans. The main towers have foundations composed of 18 bored piles with a diameter of 3 meters and a depth of 55 meters. There are also 8 sets of viscous dampers to prevent damage during an earthquake.

The Goupitan Dam is one of the tallest in China with a total height of 232.5 meters from foundation bottom to crest. The dam became operational in 2009 and was completed in 2011.
