M-14 is nice now, definately. Just be wary, if you're coming from Ann Arbor into Detroit near the overpasses they do some very crazy turns -- while these turns are nothing major, it tends to scare the living crap out of every old person on the road, and they suddenly brake. I go through here at least 3 times a week, and every time I've passed this area people slam on the brakes and go from 60+ to 40 instantly, almost causing chain reactions every time. It's just ugly, so be warned and keep some distance from the person in front of you, even if they are crawling.
