Chattanooga to Madison Road Trip: Ultimate Guide

This 280-mile road trip from Chattanooga, TN to Madison, IN follows Interstate 24, then I-65, and finally State Road 56/7. The drive takes roughly 4.5 hours without stops. It crosses the Cumberland Plateau, the Tennessee River, and the rolling hills of southern Indiana.

One quirky fact: just north of Chattanooga, the highway passes over Nickajack Lake at a point where the Tennessee River's flow is reversed by dam operations. This is one of the few places in the US where a river's direction can change daily.
