"With steep slopes on both sides of the canyon, Yachi Bridge has unusually short but heavy concrete back spans of only 220 meters that counteract the pull of each of the 400 meter halfs of the 800 meter main span. The span configuration is 71+72+77+800+77+72+71 +8x30 meters. Yachi is the largest bridge on the 77 kilometer Guiyang to Qianxi 贵阳至黔西高速公路 expressway. The truss is 8 meters deep each section 16 meters long. The back span concrete beams have a height of 8.2 meters and a width of 27.7 meters. The longest stay cable is 424 meters long and weighs 42 tons."
