Alex is correct. When coming from BHAM those are the two ways to go. Personally I would oped for the 20 to 285 south to 75 south, no matter what time of day you go thru. That is just my personal opinion.Even during the busiest part of the day you shouldn't hit traffic going that way until you near the airport on 285. Coming from that direction if you want to stop in Douglasville, Lithia Springs, Carrollton, Breman, Villa Rica, Temple or even the Mableton exits are mostly nice. I would suggest NOT stopping at the Fulton Industrial exits or Six Flags exits for many reasons. Those are very busy exits and Fulton Ind. has never been what you would call a CLEAN area. If you want to stop to grab a bite I would suggest the Hwy 5 exit in Douglasville, or Chapel Hill RD in Douglasville, those are Arbor place mall exits and have many rest. choices there , from Mickey D's to O'Charlies. I was raised out in Douglasville so i know that route and area very well. Any thing you would like to know about any of the exits, just ask.
285 to 675 is best for those coming down 75 or 85 from north of city.
