Well, rush hour traffic is generally really bad anywhere around 400. You are correct in that Holcomb Bridg Road is a bottleneck area. As far as East or West of 400, the traffic on the back roads that connect from Alpharetta into Gwinnette County through Duluth are the worst. However, if you are commuting do downtown Atlanta from there and actually getting on 400, it's about the same on either side. If you tell me where you'll be commuting to, I can probably recommend an area with the least traffic that will get you a nice home in a swim/tennis for your price range that will also have excellent schools. Feel free to contact me any time. See my web site link below for full contact information.
