I, for one, do NOT recommend taking a 5ver or TT OR MH THROUGH Atlanta at ANY time! Taking the Perimeter, a.k.a. I-285, "West" (even though you'll be traveling SOUTH! Just follow the signs for Birmingham/Tampa) is a) Not any further than 75 through downtown and b) WAY less stressful than dealing with the Canyon/Mixmaster that is 75/85/20 just south of downtown.
When we're headed for NC, I always time our arrival in Hotlanta for be between 11 AM & 2 PM; take I-285 around to I-85 N. and light out for South Carolina! There are, at times, slowdowns; but rarely does traffic come to a standstill like it does downtown.
Watch your tail swing... Keep the greasy side down and keep it 'tweeeeeeeeen the ditches, Y'all!
