French Lick to Decatur Road Trip Guide: Scenic Drive Highlights

The drive from French Lick, Indiana to Decatur, Alabama covers roughly 350 miles along US-231 and I-65, a corridor once vital for the Louisville and Nashville Railroad line that opened the Deep South to commerce in the 19th century. You’ll trace the path of iron horses through rolling hills, past coal seams, and into the Tennessee River Valley.

On this route, you cross the Ohio River at the George Rogers Clark Memorial Bridge—a 5,812-foot steel truss structure connecting Indiana to Kentucky. That bridge, completed in 1929, is a feat of Depression-era engineering and offers views of the river’s brown currents below.
