When I was studying in China. We went to Jiumenkou Pass: Nine-Arch Great Wall Bridge. The Jiumenkou Pass connecting the two banks of the Jiujiang River is the most significant part of the Great Wall. It is supported on 8 piers and 9 arches. 8,400 square yards (7,000 square meters) of rectangular granite stone slabs are embedded on the bed of the river (Travel China Guide).
