bypass Atlanta for motorhome travel..update..got it!

^^^ East & South sides will have less traffic than the North and West. Also has a higher speed limit. Yea I know, no one cares what the speed limit is.
The only other suggestion is US-441/US-129 down to Macon. And US-80 over thru Columbus. Then decied if you want to stay on US-80 joining I-85 between Aburn and Montgomery. Or take US-431 north to I-85 at Opelika AL
