Things get heavy in the morning by 7:30 am, staying thick until about 8:45am. This is barring any bad wrecks! Have one of those and things are a mess for a couple of hours. In the evening it starts to get heavy after 4:00 pm until about 6:00. The same goes for any wrecks! Keep your radio tuned to local stations during that time because they always are giving traffic reports about every 10-15 minutes during rush hours. If you do travel through Cincy on non rush hour times, you could go straight through I-75. If you are travelling during rush hours, you might opt to do the 275 loop. It does add quite a few extra miles on, but I myself prefer traveling at 65 mph and getting somewhere as opposed to stop and go traffic. If I can be of any more help, just pm me. I've lived in the Cincinnati area all my life!
