US31 through Birmingham is slow with a lot of stops. Really, I65 isn't bad. Oak mountain on the south side is a good overnight stop. Quiet and reasonable. The access to the campground is from the south end of the park.
A little secret that I just discovered is that there is an equestrian campground just inside the entrance (less than 100 yards). If you are just passing through it is a great place to spend the night. The main campground takes an extra 10 minutes each way to get to. The equestrian campground has full hookups but no bath house. Not much privacy but nice pull through sites and it is very quiet.
I go through Birmingham a lot. I try to avoid rush hour but I would rather do B'ham twice than Nashville once.
