Chicago to Kansas City Road Trip Guide: Hidden Gems & Tips

This 540-mile route from Chicago, IL to Kansas City, MO primarily follows I-55 southwest to St. Louis, then I-70 west across Missouri. A lesser-known fact: the section of I-70 in Missouri was one of the first Interstate segments built using a continuous reinforced concrete pavement technique in the 1950s, which still holds up remarkably well today. Expect a drive time of 8 to 9 hours without stops, but with recommended breaks, plan for 9 to 10 hours.

Before you depart, check if the Chicago Skyway (I-90) has tolls; an I-PASS or cash is needed. The most efficient route avoids downtown St. Louis traffic by taking I-270 north of the city.
