Indianapolis to Little Rock: Ultimate Road Trip Guide

The route from Indianapolis, IN to Little Rock, AR covers 550 miles via I-65 S, I-24 W, I-57 S, and I-40 W. A unique quirk: just outside Marion, Illinois, you cross the Ohio River at the 1,500-foot-long Cairo Bridge, a truss bridge completed in 1938. Driving this route straight takes about 8.5 hours, but with stops, plan for a full day or two.
