 Also, an unnumbered road was established from SR 30 in Reidsville to SR 26 in Metter.By the end of September 1921, the original path of SR 23 from Statesboro to Millen was shifted westward, to travel from SR 26 in Metter to SR 21 in Millen; this placed SR 23 on a concurrency with SR 26 from Metter to Graymont, the old name of Twin City.SR 23's former path was redesignated as portions of SR 46 and SR 67.
