State Route 6 (SR 6) is a state highway that travels northwest-to-southeast in the U.S. state of Georgia. It is known as Jimmy Lee Smith Parkway, Jimmy Campbell Parkway, Nathan Dean Parkway, and Wendy Bagwell Parkway in Paulding County; C.H. James Parkway in Cobb County; Thornton Road in Douglas County; and Camp Creek Parkway and honorarily as Tuskegee Airmen Parkway in Fulton and Clayton counties. It begins at the Alabama state line, where it is concurrent with US 278. Here, US 278 enters Alabama, concurrent with the unsigned state highway SR 74. Its eastern terminus is at an interchange with Interstate 85 (I-85) west of the Hartsfield–Jackson Atlanta International Airport. Route description SR 6 starts at the Alabama state line, southwest of Cedartown, and northwest of Esom Hill in Polk County, and initially heads east to Cedartown, concurrent with US 278 from its western terminus. Skirting Cedartown around the south, the highway continues east to Rockmart, where it turns sharply to the south and then southeast into Paulding County and Dallas. Bypassing Dallas to the south, SR 6 continues traveling to the southeast and travels through the southwestern corner of Cobb County, through Powder Springs, to Austell in Douglas County. In Lithia Springs, the highway approaches the intersection with US 78/SR 5/SR 8, where US 278 turns left and joins a concurrency with US 78 as far east as Druid Hills, while SR 6 continues southeast where it has an intersection with Maxham Drive, a local boulevard spanning from the Westfork Shopping Center through SR 5, and later crosses over I-20, where it has a partial cloverleaf and half-diamond interchange. Forming the county line between Cobb and Douglas counties, the highway continues traveling to the southeast, and crosses the Chattahoochee River into Fulton County. Curving to the east, the highway crosses I-285 and reaches its eastern terminus at the western edge of Hartsfield–Jackson Atlanta International Airport in College Park. The entire length of SR 6 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. History SR 6 was established at least as early as 1919 from SR 1 in Cedartown east-southeast through Dallas to SR 8 in Austell. By the end of September 1921, it was extended westward to the Alabama state line. By October 1926, US 78 was designated on SR 8 at SR
