The Mazhao expressway is the last link of the G85 expressway that had not been completed due to the difficult terrain that required the construction of many large beam bridges and tunnels in the mountains north of Zhaotong City in Northeastern Yunnan Province. Of these 8 large bridges, the highest is the Niujiagou Bridge that crosses a deep gully next to the Hengjiang River.
Prior to construction this bridge was to be called Xiongjiagou Bridge.
The Niujiagou Bridge is most notable for having 2 of the tallest piers in Yunnan Province at 140 meters. They support a span configuration of 2x30 +95+180+95 +4x30 meters. Several other high bridges on the route also overlook the Heng River gorge including Daguanhe, Sayuhe, Paotongwan, Longdongwan, Zhilaigou, Shanchagou and Yaoyan. I hope to find out the heights of these other beam spans soon.
