We have made the route between East Texas and Atlanta many times towing various fifth-wheels. We never had any trouble just staying on I-20 until it intersected with I-285 (We were usually headed to Stone Mountain Park). And on the return just the reverse: I-285 to I-20 then right through town. I don't remember a single time that we had any delay at all. Of course we we were not coming through during rush hours--except once when we got up early because we needed to get home in one day. (7:00 o'clock in Atlanta was 6:00 o'clock in Texas so we made it) Amazingly we had a good smooth trip through Atlanta on I-285 and I-20 at 7:00 in the morning. I know it's hard to believe; maybe we were just lucky. I'm not saying driving on 285 is fun, but we always made it without problems or delay.
