Balinghe Bridge

　　    Situated at the junction of Guanling Autonomous County and Huangguoshu Scenic Area, Balinghe Bridge is a super-large bridge spanning the Balinghe Grand Canyon on the Zhenning–Shengjinguan Expressway, part of the Shanghai–Ruili National Trunk Highway. The bridge is 2,237 meters long, with a main span of 1,088 meters and a vertical height of 370 meters above the river. It was officially opened to traffic on December 23, 2009, marking the full completion of the Shanghai–Ruili section of China’s “Five Verticals and Seven Horizontals” national highway network. The bridge is currently the first steel truss stiffened-girder suspension bridge in China to span over 1,000 meters. It holds six world and national records: the longest main span among large-span mountain bridges in the world, China's first long-span steel truss girder suspension bridge, the longest tunnel-type anchor on the western bank, the heaviest gravity-type anchor on the eastern bank in China, China’s first bridge built in mountainous and hilly terrain, and the highest investment single bridge project in Guizhou.
