Tangjiahe Bridge is part of a new 3rd level local highway that will connect mountainous regions of Baojing County that have been separated by the deep gorge of the Tangjia River. The steep canyon walls will support a spectacular red concrete filled steel arch span of 200 meters. The 8.5 meter roadway will have a total length of 280 meters with two 20 meter approach spans on either side of the main arch. The 8 steel arch ribs will rise 40 meters to the crown giving the arch a span to rise ratio of 5:1. The bridge will be approximately 160 meters above the surface of a reservoir approximately 20 meters deep.
A parallel one-lane construction access catenary suspension bridge will be nearly as high as the main bridge.
