State Route 9 (SR 9), (known locally as Highway 9) is an north–south state highway in the northern part of the U.S. state of Georgia. It travels from Atlanta to Turners Corner, north-northeast of Dahlonega. It is concurrent with U.S. Route 19 (US 19) from its southern terminus, in northwest Atlanta, to Roswell Road at Interstate 285 (I-285), in Sandy Springs. It is also concurrent with US 19 from Dahlonega to its northern terminus at US 129/SR 11. SR 9 parallels US 19/SR 400 for much its length. Because of its proximity to US 19/SR 400, it is a viable alternate to the congested "Alpharetta Autobahn". Along its length, SR 9 travels through the cities of Atlanta, Sandy Springs, Roswell, Alpharetta, Cumming, Dawsonville, and Dahlonega. Route description At its furthest southern point, SR 9 begins at the intersection of US 19 (14th Street N.W.) and US 41/SR 3 (Northside Drive) in Atlanta. It travels to the east to an intersection with West Peachtree Street N.W., and turns north here, shortly after crossing over I-75. SR 9 is signed as Peachtree Street N.W. from just south of I-85, and crosses under I-85 just north of the I-75/I-85 (Downtown Connector) interchange north of Downtown Atlanta. Just south of Piedmont Hospital, SR 9 changes names from Peachtree Street N.W. to Peachtree Road N.W. From its intersection with SR 141, which begins here, SR 9 is signed as Roswell Road N.W. The highway continues to travel generally north, crossing I-285 at exit 25. From its southern terminus to this point, SR 9 also travels concurrent with US 19, but continues north on its own from this point to Dahlonega. It also largely parallels SR 400 from here, travelling through Sandy Springs and crossing the Chattahoochee River into Roswell and has reversible lanes up to its intersection with SR 120. The two highways are concurrent from here to its intersection with Old Milton Parkway. SR 9 is interchangeably signed as Atlanta Street or Alpharetta Street on this stretch, and as Alpharetta Highway from downtown Roswell and crosses SR 92 and SR 140 and passes North Fulton Regional Hospital. From downtown Alpharetta, it is interchangeably signed as Cumming Highway, Atlanta Highway, or Atlanta Road. Near exit 14 of SR 400, SR 9 starts to travel concurrent with SR 20, until they split again in downtown Cumming. From here, SR 9 is signed as Dahlonega Highway, and
