Peoria to Kansas City Road Trip: Hidden Gems on I-74 and I-35

One of the most historically freighted 320-mile drives between the Midwest's industrial spine and its western frontier begins in Peoria, Illinois—the site of the world's first Caterpillar Tractor Co. factory (1925). The route uses I-74 west to Bloomington-Normal, then I-55 south toward St. Louis before jogging west on I-270, I-72, and US-36 to the outskirts of Kansas City, MO. An alternative is to take IL-9 west to US-67 to I-80, but the I-74/I-35 corridor is faster and more scenic.

This road trip can be completed in about 5 to 6 hours of driving time, but you'll want to stretch it over two days to absorb the best stops Peoria, IL to Kansas City, MO offers. The question 'is it worth driving Peoria, IL to Kansas City, MO?' is answered with a resounding yes when you factor in the surprising natural landscapes, historic towns, and local flavors along the way.

The main route is well-paved interstate and US highways. I-74 and I-55 are four-lane divided highways with 70 mph limits. US-36 from Hannibal to Kansas City is a two-lane highway in places, but generally well-maintained. Truck traffic is moderate outside of cities. Gas stations and fast food are available every 20-30 miles. A detour via Macomb and Quincy on US-67 is slightly shorter but less serviced.

Fuel prices average $0.10-0.20 cheaper in Illinois than Missouri. Fill up in Springfield or Decatur before crossing into Missouri. The route passes through Central Time Zone entirely; no time change. Toll roads: none on this route.
