The Unexpected Stops That Made My Route 66 Illinois Drive Unforgettable

In May, I drove Route 66 through Illinois to commemorate the Centennial. I'd been researching Route 66 as part of Only In Your State's partnership with the Route 66 Centennial, and I had a list of must-visit stops in Illinois to visit—a packed itinerary, as it were.

What I wasn't prepared for was how taken I'd be by the beauty of the road trip through Illinois, and how quickly my itinerary would be expanded for unexpected detours. I'd only ever visited the Chicago area, and I wasn't expecting how gorgeous the Illinois heartland would be. Tunes up and windows down, I drove slowly and found myself stopping in between the destinations on my itinerary—and, in some cases, skipping them altogether. I'm glad I did; there's so much to discover along Route 66 in Illinois: under-the-radar gems, random roadside attractions, and small towns that deserve their 15 minutes of fame!

Why I Took Route 66 Through Illinois

Why drive Route 66 through Illinois? Simply put: I was on assignment! Only In Your State is the official partner of the Route 66 Centennial, and I'd been invited to a baseball game at Joliet Prison as part of the 2026 kickoff.

I live in Northern Kentucky, so Illinois is the closest Route 66 state to me. As such, I created an itinerary that got me to Chicago in a day, to Joliet for the kickoff the following afternoon, and the following day, I would drive Route 66 through Illinois back to my Kentucky home. I had a list of iconic stops along Route 66 in Illinois, and I was excited to see them IRL.

The Illinois Stretch of Route 66 Surprised Me

Having never driven through the true heart of Illinois, I was gobsmacked by the quiet, unassuming beauty of the central part of the state as I drove, slowly, south, from Chicago.

As you get into the more rural part of Illinois, the landscape opens up, and the skies feel big—like, American Southwest big. Now, I've taken many road trips through rural Ohio and Indiana, but Illinois was different. Somehow, the stretches of Route 66 through central and then south Illinois felt both grounding and aspirational. Driving down a road with so much history, along a stretch that so many had traveled before me, was unexpectedly emotional. So I set my car on cruise, turned the music off, and let myself take it all in.

The Best Unexpected Stops Along Route 66 in Illinois

1. Atlanta, Illinois - A Small Town Teeming with Route 66 Pride

I knew I'd be visiting Atlanta, Illinois, to see the American Giants Museum, and I'd long been looking forward to that. However, after parking my car and wandering through the town's headliner, I found myself curious to explore more. I'm glad I did, because downtown Atlanta is teeming with local businesses that fully own their space in Route 66 history; I loved my conversation with the owner at Arch Street Artisans, where I picked up several Route 66 laptop stickers and quirky themed coasters as souvenirs.

2. Country-Aire Restaurant - A Delightful Diner Along Route 66

I was hungry after driving and exploring all morning and needed fuel! I pulled into a gas station and had my phone out, ready to find the nearest Starbucks, when I noticed a larger-than-life rooster and waitress directing folks to the restaurant next door. Turns out I'd discovered Country-Aire Restaurant, a family-style eatery in Atlanta, Illinois, known for all-you-can-eat specials and friendly, small-town sensibility. After multiple cups of coffee and a slice of apple pie, I was ready to continue my journey.

3. The Original Route 66 Road

I felt like Dorothy following the Yellow Brick Road as I got out of my car to stroll along the original Route 66 in Illinois. Now, I realize this original stretch is a known stop along Route 66 in Illinois, but what you need to understand is that it's not simply a stop or stretch of old road; there's a quiet sense of peace and possibility here. The skies are big, and the road is surrounded by farmland. Getting out of my car and wandering on and off the road felt momentous, truly like the start of something. That's the spirit of Route 66, to me.

4. A Photo Op in Lockport, Illinois

Ahead of the 2026 Centennial, a Route 66 monument with a cut-out designed for photo opps was erected in Lockport, Illinois. I definitely stopped to check it out (you'll find it at 1327 S. State Street), and even though Lockport sits just slightly off the official Mother Road, this spot is a crucial part of a new 12-monument installation celebrating the First Hundred Miles of the historic Illinois route.

5. Old Joliet Prison - A Tour Worth the Detour

Most people stop by Old Joliet Prison for a photo op outside the barbed-wire fence or the long brick walls. Perhaps a quick stop to wander around the iconic prison. And while the old jail is certainly worthy of a photo-op, its history is fascinating and best experienced via a prison tour.

6. Litchfield - A Bustling Route 66 Stop

About an hour and a half from Atlanta, I decided to stop in Litchfield for a late lunch at the Ariston Cafe. Operating continuously since 1924, this iconic cafe is hailed as the oldest continuously operated restaurant on Route 66 from Chicago to Santa Monica. I went with a turkey club, and it hit the spot - 10/10, no notes.

7. Mt. Olive - All-American Town with Mayberry Vibes

After visiting Litchfield and waxing poetic about the town's charm, one of the local business owners directed me to Mt. Olive, a darling little town 15 minutes south on Route 66 with coal mining roots and a historic cemetery home to activist Mother Jones. In Mt. Olive, Soulsby Service Station is as old as the Mother Road herself; built in 1926, it boasts the iconic yellow Shell pumps and operates as a 1950s-era roadside museum.

Why Slowing Down Made This Road Trip Better

It's one thing to say the journey is the destination, but with Route 66, that's the whole point. The myriad roadside stops erected along the Mother Road were done so as beacons for road-weary travelers—a neon sign flashing "Vacancy" at a roadside motel, a larger-than-life chicken pointing travelers to an unassuming town diner, a giant lumberjack and his faithful ox... Route 66 is all about the journey. And while you can certainly put your head down and drive from Chicago to Santa Monica with a carefully curated itinerary meant to get you from Point A to Point B, Route 66 rewards travelers who take their time.

Because when you stop the car, get out to stretch, eat, explore, talk to locals—this is where the magic happens. And for me, slowing down made my trip along Route 66 through Illinois one of the most memorable experiences I've had on the road.
