Near the intersection of Wilson Bridge and Martin Bridge roads off Exit 154 of Interstate 85 in Banks County, there once was a community called Arp. Dr. H.P. Quillian, a White County native, is said to have practiced there, and the place even had its own post office from 1880 to 1905, probably inside a general store, according to postal records. Only a house, pastures and a farm are in the immediate vicinity today.
