In 2016 Qingshuihe Bridge will surpass Balinghe Bridge as the highest and longest suspension span in Guizhou Province.  The giant new crossing is part of the Guiweng expressway 贵瓮高速公路 that will connect the capital city of Guiyang with Weng'an.  The 230 and 224 meter tall towers support a steel truss main span of 1,130 meters that ranks among the 20 longest spans on earth.

An alternate Qingshui River crossing several kilometers to the south was studied that would have had an even greater deck height but the main span would have been much smaller.  The highway planners may well have decided to go with the northern route knowing their bridge could then become an even bigger and higher "sequel" to the famous Balinghe Bridge.

Qingshuihe might also hold the record for the fastest construction ever for a bridge over 1 kilometer in length with a total construction time of 3 years.  Crews were reportedly working 7 days a week on multiple shifts including holidays.

The second highest and longest span bridge ever built over the great Wujiang River, the Liuguanghe Bridge is also one of the tallest with the west pier stretching 248 meters into the sky.

The Xiqian expressway bypasses the older 2-lane Guibi Road that opened in 2001 and connected Qianxi with the G75 expressway. The newer route also allowed a more direct connection with the cities of Xifeng and Kaifeng.

The giant main span of 580 meters is most notable for the short back spans that required the higher cable stays to be bundled more closely together. Like many giant spans that cross the Wu River, Liuguanghe Bridge crosses a reservoir from a downstream dam that can vary the height from 328 meters when the lake is full to as high as 375 meters if measured down to the original level of the Wujiang River.

作为乌江上第二高也是第二大桥,六广河高速公路桥也是桥塔最高的桥之一,西桥塔高248米。

息黔高速公路取代了2001年修建的贵毕公路,将黔西县和G75兰海高速连接起来。新高速也使黔西、息烽、开阳之间有更便捷的交通要道。

该桥主跨580米,引人注目的是边跨较短。和乌江上许多其它高桥一样,此桥跨越一个水库,当水库满水位时,桥面距离水面高328米;距离原始水面高375米。
