We went through Birmingham last summer on the way to Alaska. That was the worst stretch of road in the whole 17000 miles of the trip including anything on the Alaska Highway. I was down to about 35 mph in town and that was probably too fast for the road conditions. Next time I will go around Atlanta.
I knew it was rough but your description really put it in perspective. I'm really hoping a year made a difference. I'll update my post after the trip. May change my return route to I55 if it's still bad. Thanks for the feedback! T-Man
