Best advice to drive straight through Atlanta on 75 and in the middle of the night. Just returned from Florida and tried the west side Atlanta by-pass on 285. Big mistake... road construction everywhere and down to 1 lane in lots of spots, with traffic backed up for 5 miles. Where there was no road work going on, big cracks and holes in concrete pavement. Another major delay could be driving south through Chattanooga on 75. Took me over 2 hours to get through on a Thursday afternoon. On the return trip, drove through about 6 AM on a Sunday morning to miss traffic.
