Fuel costs average $0.12/mile for a midsize car; expect to refill 3–4 times. Gas stations are plentiful along interstates, but between Paducah and Cape Girardeau, stations are sparse for 50 miles. Toll roads: none on this route. Rest areas every 30–40 miles on I-24 and I-70, with clean restrooms and vending machines.

Best months: April–May (wildflowers) or September–October (fall colors). Summer brings high humidity and heat, especially in the Mississippi Valley. Winter can bring ice storms near the Ozarks. For real-time road conditions, check state DOT apps.
