2016
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 136 meters. They support a span configuration of 2x30 +95+180+95 +4x30 meters. There are at least 7 other high beam bridges on the route that overlook the Heng River gorge including Daguanhe, Sayuhe, Paotongwan, Longdongwan, Zhilaigou, Shanchagou and Yaoyan. This stretch of expressway will be 97% bridge and tunnel for at least 20 kilometers.
