- Junction City is the southernmost city in Arkansas. Straddling the state line with Louisiana, Junction City has two city governments and exists in Union County, Arkansas; Union Parish, Louisiana; and Claiborne Parish, Louisiana. Junction City was created by the Arkansas Southern Railway Company, which was formed by the directors of the South Arkansas Lumber Company. Both businesses were incorporated in August 1892, and the railroad began building a line from El Dorado (Union County) south to the state line.
