You’re staring at the map. Des Moines to Dallas Texas is roughly 700 miles of straight, vertical asphalt down the spine of America. Most people look at that line on I-35 and think it's just a grueling, gray slog through cornfields and construction. They’re halfway right. If you don't plan it correctly, it’s a nightmare of wind-buffeted lanes and overpriced gas. But if you know where the actual speed traps are and which towns have the best brisket hidden behind a Sinclair station, it’s actually one of the most efficient road trips in the Midwest.
Honestly, the "flyover country" label does this route a massive disservice.
Driving this stretch is basically a masterclass in the transition from the humid, rolling hills of the North to the sprawling, high-heat concrete of the South. You’re crossing the 40th parallel and diving deep into the Sun Belt. It takes about 10 to 11 hours depending on how heavy your foot is and how much the Kansas City traffic decides to hate you that day.
The I-35 Reality Check
I-35 is the literal backbone of this trip. It’s a vital trade corridor. That means trucks. Lots of them. From Des Moines to Dallas Texas, you are sharing the road with thousands of 18-wheelers carrying everything from Iowa pork to Mexican electronics.
The first leg takes you through southern Iowa. It’s hilly. If you’re driving in the winter, this is where things get dicey. The Iowa Department of Transportation (IDOT) is usually on top of things, but the crosswinds near Osceola can shove a high-profile SUV right out of its lane. You’ve got to stay awake here. Once you cross into Missouri, the landscape flattens slightly, and you’re barreling toward Kansas City.
Kansas City: The Great Bottleneck
You will be tempted to stay on I-35 through the heart of KC. Don't. Unless it’s 2:00 AM, the downtown loop is a chaotic mess of shifting lanes and sudden exits. Use I-435 to bypass the madness if you're just trying to make time. However, if you have an hour to spare, stopping for Joe’s Kansas City Bar-B-Que—the one in the gas station on West 47th Ave—is a rite of passage. It’s better than any food you’ll find on the highway for the next four hundred miles.

Kansas is where the trip gets mental.
I-35 through Kansas is mostly a toll road (the Kansas Turnpike). It’s well-maintained, but it's boring. Like, soul-crushing boring. The Flint Hills offer a bit of visual relief with their undulating tallgrass prairies, but mostly you’re just watching the odometer click. Pro tip: Check your tires in Wichita. The heat starts to ramp up here, and I-35’s pavement temperature can skyrocket, which is hell on older rubber.
The Oklahoma Gauntlet
Crossing the border into Oklahoma feels different. The red dirt starts appearing. The wind picks up.
Oklahoma City is the halfway point. It’s basically the "reset" button for the drive from Des Moines to Dallas Texas. If you’re staying overnight, the Bricktown district is fine, but the real gems are in the Plaza District. More importantly, keep an eye on the weather. If you’re making this drive in May or June, you are in the heart of Tornado Alley. Use the National Weather Service mobile site. Do not rely on "vibes" or clear skies. Storms here build in minutes, not hours.
South of OKC, the Arbuckle Mountains offer the only real elevation change on the whole trip. It’s not the Rockies, but after six hours of flat plains, those limestone ridges look like the Himalayas. Stop at Arbuckle Mountain Fried Pies in Davis. If you don't, you’ve fundamentally failed the road trip. The savory ones are good, but the blackberry pie is the actual reason people live in this part of the country.

Crossing the Red River into Texas
Once you hit the Red River, you’re in Texas. But you aren’t in Dallas yet.
You still have Gainesville, Sanger, and the sprawl of Denton to navigate. This is where the traffic becomes "Texas Fast." In Iowa, people go 5 mph over the limit. In North Texas, the speed limit is 75, but the flow of traffic is often 85. If you aren't comfortable with aggressive merging, stay in the center lane.
The I-35E and I-35W split in Denton is the final boss of this journey. To get to Dallas, stay left for I-35E. If you end up on 35W, you’re going to Fort Worth. It’s a common mistake that adds 45 minutes to your trip.
Logistics, Fuel, and Hidden Costs
Let's talk money. This isn't a cheap drive anymore.
- Tolls: Between the Kansas Turnpike and the potential for North Texas Express lanes, budget about $25-$40 for tolls if you don't have a K-Tag or TxTag.
- Gas: Prices usually drop once you hit Oklahoma and Texas. Iowa gas taxes are higher. Fill up just enough to get to the Missouri or Oklahoma border to save a few bucks.
- Speed Traps: Small towns like Eagleville, Missouri, and certain stretches in southern Oklahoma are notorious. If the sign says 65, go 65. The highway patrol doesn't care about your ETA.
The Best Stops You’ve Never Heard Of
Most travel blogs tell you to go to the big museums. Forget that. If you're doing the Des Moines to Dallas Texas run, you want the weird stuff.

- Precious Moments Chapel (Carthage, MO): It’s a slight detour off I-35, but it is one of the strangest, most earnest displays of kitsch in the United States.
- The Oklahoma City National Memorial: It’s heavy, but it’s a necessary stop to understand the resilient culture of the people you’re driving past.
- Buc-ee’s (Melissa or Denton, TX): You cannot enter Texas for the first time without stopping at a Buc-ee’s. It’s a gas station with 100 pumps, brisket sandwiches, and bathrooms cleaner than most hospitals. It’s a cultural phenomenon.
Seasonal Hazards
Winter is the silent killer on this route. A "clipper" system can drop six inches of snow in Des Moines, while a "blue norther" creates black ice in Oklahoma. If the forecast mentions "freezing rain" in North Texas, stop. Just stop. Texas does not have the salt trucks or the infrastructure to handle ice, and I-35 becomes a literal skating rink for semi-trucks.
Conversely, summer is an engine killer. If you’re driving an older car, watch your temp gauge as you cross the Red River. Temperatures in Dallas frequently stay above 100°F for weeks. Your AC will be working overtime, and so will your cooling system.
Making the Trip Productive
Since you're looking at 10+ hours in the cockpit, this is the time for long-form audio. This isn't a 20-minute commute.
Download some heavy-duty podcasts or audiobooks. This is the length of about three typical non-fiction books. It’s also a great time to use the Hands-Free features of your phone to catch up with family, though cell service can occasionally drop out in the rural stretches between Wichita and OKC.
Final Strategy for the Arrival
As you descend into the Dallas-Fort Worth metroplex, the skyline will pop up suddenly. It’s impressive. But stay focused. The "Mixmaster" interchange in downtown Dallas is one of the most complex in the country. If your GPS tells you to take a specific exit, do it immediately. Missing an exit in Dallas means a five-mile detour because of the one-way frontage roads that define Texas highway design.
Actionable Next Steps
- Check the K-Tag/Pikepass reciprocity: You can actually use certain toll tags across state lines now. Check if your current pass works in Kansas and Texas to avoid the "pay by mail" upcharges which are usually double the price.
- Download the GasBuddy app: The price variance between a station in rural Kansas and one in suburban Dallas can be as much as 50 cents per gallon.
- Inspect your cooling system: If it’s summer, ensure your coolant is topped off and your fans are engaging. The Texas heat is unforgiving to Iowa-prepped vehicles.
- Plan the KC Bypass: Look at the traffic map 30 minutes before you hit Kansas City. If I-35 is red, immediately commit to I-435. Don't wait until you're in the lanes.
- Book a hotel in Moore, OK: If you can't make the full 11-hour push, Moore is south of OKC and puts you in a great position to beat the morning Dallas traffic the next day.
