Montevideo is another crossroads community of Elbert County, located just up the road from Rock Branch. While this old store is located in Elbert, most of the settlement is located in Hart County, which is just across the road. In fact, Montevideo Road itself makes up much of the southern border Hart County. Presumably named for the South American city, Montevideo may have originated as an earlier plantation or farm. A post office served the community from 1857-1903.
