Few road trips weave through such a tapestry of American history and natural splendor as the 250-mile drive from Chattanooga, TN to Lexington, KY along I-75 N.

Driving time is typically around 3 hours and 45 minutes without stops, but the journey rewards those who linger. From the Tennessee River gorge to the gentle horse farms of Kentucky, the landscape shifts dramatically.
