 In 1988, all of SR 325 was transferred to Union County upon completion of the Appalachian Developmental Highway segment that also resulted in the turnback of Old US 76 on what is now Blue Ridge Highway.Local business owners protested the move and petitioned the legislature and Georgia DOT to restore the route.On April 13, 1989 the state restored most of the route except for the portion south of US 76/SR 515 (APD), which remains a county road.
