I 75 is worst around the Atlanta Georgia area, and if I can I always try to avoid that area. Headed back from Jackson Center, you might consider staying on I 75 until you hit Chattanooga Tennessee, then head east and take a detour through the great Smoky Mountains. That is a very scenic route, especially in the spring and fall of the year. You have the option to take the interstate all the way to Charlottesville, and then head south through Savannah if you’d like, or if you’re a bit more adventurous wander off the interstates a bit and take some of the state routes down through North Carolina, South Carolina, Georgia and into Florida via those routes.
If you can time your trip such that you overnight around Chattanooga or Rocky Top Tennessee and head out in the morning, when the hills are still emerging in the low, early sunlight from the mist, that is a blissful sight to behold.
