Shuangbao Bridge is the world's largest double arch bridge with two back to back concrete filled steel tubular spans of 380 meters or 405 meters if measured between the center of the beams. The giant 6-lane structure crosses both the Dadonghe and Xiaohegou Rivers and is part of a new G65 expressway link that goes south from Penshui City to the Youyang to Yanhe Expressway.
A 150 meter high temporary construction bridge was built approximately 240 meters across the west side river to allow trucks and personnel to access the mountain that will support the center arch abutments of the Shuangbao double span arch bridge.
