So, you're looking at a map and wondering exactly how far is Atlanta from Detroit. Maybe you're planning a massive move to the South, or perhaps you're just dying for some decent Coney dogs and leaving the Peach State behind for a weekend. Whatever the reason, the "distance" isn't just one number. It depends entirely on whether you’re white-knuckling a steering wheel on I-75 or scrolling through movies at 30,000 feet.
Honestly, people mess this up all the time. They look at a straight line on a map and think, "Oh, that's not bad," but the reality of the Midwest-to-South pipeline involves a lot of mountains, some unpredictable Ohio weather, and the inevitable Atlanta traffic that turns a "12-hour drive" into a test of human patience.
The Raw Numbers: Atlanta to Detroit Distance
If you were a bird flying in a perfectly straight line, the distance is roughly 595 to 600 miles. That’s the "as the crow flies" measurement. But unless you have wings, that number is basically useless.
For the rest of us, here is the breakdown of what you're actually looking at:
- By Car: You’re looking at about 710 to 720 miles via the most direct route.
- By Plane: The flight path covers about 600 miles and takes roughly 2 hours.
- The "Time" Factor: Driving usually eats up 11 to 13 hours, depending on how many times you stop for Buc-ee's or gas.
Driving the I-75 Gauntlet
Most people making this trek will spend 99% of their life on Interstate 75. It is the concrete artery that connects the Great Lakes to the Deep South. Starting in Detroit, you’ll cut through the flat farmlands of Ohio, hit the rolling hills of Kentucky, climb the stunning (but steep) Tennessee mountains, and finally descend into the humid sprawl of Georgia.
The Route Breakdown
You start in the 313, heading south through Toledo. Most people don't realize that Ohio actually takes up a massive chunk of this trip. You’ll pass through Dayton and Cincinnati. Crossing the bridge from Cincy into Kentucky is actually one of the coolest views on the trip, especially at night when the city lights reflect off the Ohio River.
Then comes the "Mountain Part." Between Lexington and Knoxville, the road gets curvy. If it’s winter, this is where things get sketchy. A light dusting of snow in the Jellico Mountains can shut down the whole interstate. After you clear Chattanooga, you’re basically home free—until you hit the Marietta/Atlanta perimeter.
Real Talk on Gas and Tolls
Driving a standard sedan? You’ll probably spend between $85 and $120 on gas (at 2026 prices). The good news? There are zero major tolls on the direct I-75 route between these two cities. You might run into a small bridge toll if you veer off-course, but the main path is free—well, besides the cost of your sanity.
Flying: The 2-Hour Jump
If you aren't in the mood to spend half a day in a car, flying from Hartsfield-Jackson Atlanta International (ATL) to Detroit Metropolitan (DTW) is a breeze. Both airports are massive hubs.

Delta Airlines basically owns this route. Since both cities are major Delta hubs, you can find a flight almost every hour. You also have Spirit and Frontier if you’re trying to save money, but watch out for those baggage fees. They’ll get you.
- Total Air Time: About 1 hour and 50 minutes of actual flying.
- Gate-to-Gate: Usually 2 hours and 15 minutes.
- The "Hidden" Time: Remember, ATL is the busiest airport in the world. You need to get there 2 hours early. Add the 45-minute drive to the airport and the time it takes to get an Uber at DTW, and your "2-hour trip" is actually closer to 5 or 6 hours. Still beats driving.
Is it Worth the Road Trip?
Sometimes the distance is the point. If you have an extra day, there are some spots along the way that make the 700 miles feel shorter.

- The Kentucky Horse Park: Just north of Lexington. Even if you don't like horses, the rolling blue-grass hills are a vibe.
- Moon Pies in Chattanooga: Stop at the Tennessee Riverfront. It’s a great way to stretch your legs before the final two-hour push into Atlanta.
- Cincinnati Chili: You either love it or hate it. Stopping at a Skyline Chili is a rite of passage when driving south from Detroit.
Practical Logistics for Your Trip
Before you head out, check the weather in the Cumberland Gap area. It's the midpoint near the Tennessee/Kentucky border. I've seen it sunny in Detroit and clear in Atlanta, but a total fog-out or ice storm right in the middle.
If you're driving, try to leave Detroit around 4:00 AM. This sounds miserable, but it puts you through Cincinnati before the morning rush and, more importantly, gets you into Atlanta around 5:00 PM. Actually, scratch that. Never arrive in Atlanta at 5:00 PM. Aim to arrive either before 3:00 PM or after 7:00 PM to avoid the legendary gridlock.
Next Steps for Your Journey:
- Check the I-75 traffic cams specifically for the Jellico Mountain pass if you're traveling between November and March.
- Compare flight prices on a Tuesday; Delta often drops the ATL-DTW regional rates mid-week.
- Download your podcasts before you hit the mountains—cell service can get spotty in the rural stretches of Kentucky.
