If you're looking for a meeting place or a good stop around ½ or halfway between Castelfranco Emilia and Bagnacavallo, you can try Castenaso, Italy, which is about half an hour east of Castelfranco Emilia, or about half an hour west of Bagnacavallo.
About ⅓ or a third of the way, you can stop at Bologna, Italy. This is about half an hour southeast of Castelfranco Emilia.
If you drive straight through without stopping at all, the total distance is 96 km. The distances shown above don't include local roads to get into each town, so if you're planning a long road trip, make sure you factor in traffic and road conditions, rest stop breaks, and interesting detours along the way. If you're in a rush, you can do the trip with zero stops, and your total travel time would be around 1 hour, 11 minutes.
