The expressway section stretches 9.86 kilometers from where Tuochuan Township in Jiangxi meets Qimen County in Anhui. The Fengshan Water Bridge and Nanshan Road Bridge are two major projects along the line, which collectively involve the erection of 156 60-meter-span and six 30-meter-span steel-concrete composite beams. Of them, the 60-meter-span beams are π-type steel-concrete composite beams with the largest span in China. The heaviest measures 380 tons in weight.In terms of steel beam factory manufacturing, it needs to construct a 432m on-site assembly workshop, and arrange 4 sets of steel-...
