Longest natural arch

According to Official Guinness Records,

The natural arch with the greatest span discovered to date is Xian Ren Qiao (Fairy Bridge), northwest of Fengshan in Guangxi Province, China. A subclass of arch known as a natural bridge, Xian Ren Qiao was formed by the Buliu River carving through limestone karst terrain. An expedition by the Natural Arch and Bridge Society in October 2010 measured its span to be 400 ft plus or minus 15 ft (121.9 m +/- 4.6) m.The feature is only accessible via a three-hour trip by raft, owing to its remote location.
