When I went to Georgia Tech in 1959-61 traffic in Atlanta was a mess and the Expressways were under construction.
When I worked as a field engineer for a company based there in the 70's traffic in Atlanta was a mess and the Expressways were under construction.
When I went to through there two years ago traffic in Atlanta was a mess and the Expressways were under construction.
That said, I would try to hit it right after 10:00 AM and get out as quickly as possible. No stopping for lunch or to go potty.
Better yet. go way out of the way to avoid it.
