For those of you that are avoiding I95, thank you. My DD is there and they have a big mess with the flooding. Unless you have lived through flooding like that you can't imagine the mess, horror and stress those in the area are going through.
As you travel through Atlanta, if you come in on I85, stay on it and then take 75 South as they divide. I would seriously taking the I85-I75 connector straight through time rather than I285 around town. 285 is always extremely busy with lots of big trucks pushing all the lanes, since they can't go through town.
