 The only portion of SR 60 that is part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense, is from just south of the interchange with I-985/US 23/SR 365, in Gainesville, to the northern end of the US 19 concurrency, north-northeast of Dahlonega.The roadway that would eventually become SR 60 was established at least as early as 1919 as part of SR 9 from south-southwest of Dahlonega to north-northeast of the city.By the end of 1926, the portion of SR 9 south-southwest of the city had a "completed semi hard surface".
