Unless they have repaved the first 20 miles from the border the road is like it's bombed out. It's rough to say the least. Was through there last year and OMG, worst road I've been on in a long time. Go slower than the speed limit. You will bounce everything out of the cupboards if it's not packed well. Make sure things in the refrigerator are securely in place too.
Other than that it is 4 lane divided expressway so no issues there. Pay attention at Ann Arbor because 23 merges on the left with MI 14 so you have 2 miles to get to the right to make the interchange to continue north on 23. If you miss it you will end up going around downtown Ann Arbor and dump onto 94.
