Once SR 5 becomes concurrent with I-575, averages increase drastically, with a route high of 93,000 vehicles seen south of Woodstock, close to I-75. Numbers generally decrease as the route travels further north, going from the mark seen in Woodstock down to 59,000 in Holly Springs, around 55,000 in Canton, and further down to 26,000 near Ball Ground. Once the freeway portion of the route ends in Pickens County, averages fall further from around 24,000 to around 12,000, but stabilize in that vicinity from Talking Rock in Pickens County all the way through Ellijay in Gilmer County to Blue Ridge in Fannin County. As SR 5 approaches its northern terminus, vehicle load decreases once more to a low of 7,200, and hovers around 9,000 as the Tennessee state line is reached. With the construction of I-575 and other projects between Cobb and Gilmer counties, SR 5 saw significant routing changes in the 1980s and 1990 (see History below for additional details). All of the former routing of SR 5, parallel to I-575, and the new routing in Pickens and Gilmer counties, still exists today, and is utilized by local traffic. From the northbound exit 267A on I-75, the old routing of SR 5 follows what is today locally known as Canton Road Connector (and is signed as SR 5 Spur), which merges into Canton Road. This routing parallels I-575 very closely to its east as the old SR 5 routing heads north through the heart of Woodstock. The local road name changes to Main Street through Woodstock, and to Holly Springs Parkway on its way to Holly Springs, where it crosses under I-575 to its west at exit 14. As the old route travels through Canton, it becomes briefly concurrent with SR 140 (and is signed as SR 5 Bus.), then crosses under I-575 once more to its east again (at exit 20), and heads northeast as Ball Ground Highway. Rarely more than separate the old routing and I-575/SR 5/SR 515, as the old SR 5 passes through the heart of Ball Ground (where it is again signed as SR 5 Bus.), and it briefly becomes concurrent with SR 372. "Old Highway 5" continues north as Canton Road/Canton Highway, now somewhat further removed from the current SR 5, and travels through Nelson, then becomes concurrent with SR 53 Bus. into Jasper.
