We eventually arrived in Nanba, 120 miles north of Chengdu where an existing three span arch river crossing had collapsed. Also, a ten span river crossing under construction had dropped most of its precast voided slab spans into the river and the two-column bents had been distorted. A temporary structure was being constructed by launching Bailey Bridges onto new RC pier walls when we arrived. In the meantime, vehicles were driving across the river on fill material laid over culverts.
