Ann Arbor to Madison Road Trip: Ultimate Guide

The drive from Ann Arbor, MI to Madison, IN covers roughly 320 miles along a route that weaves through Ohio before dipping into Indiana. A peculiar detail: the route crosses the Great Miami River near Dayton, a waterway that carved the region's glacial history.
