You'd think a 20-mile trip would be a piece of cake. In most parts of the country, 20 miles is a quick fifteen-minute zip down the highway where you barely have time to finish a single podcast episode. But if you’re measuring the distance from Arlington TX to Dallas TX, you quickly realize that miles are a "kinda" useless metric in North Texas.
Here, we measure distance in minutes. Or hours. Sometimes, if I-30 is having a particularly bad day, we measure it in existential dread.
The raw math is simple enough: downtown to downtown is roughly 20 miles. If you’re leaving from the University of Texas at Arlington (UTA) and heading toward Reunion Tower, you’re looking at about 22 miles. If you’re starting at AT&T Stadium, it’s closer to 19. But honestly, those numbers don't tell the real story of the trek across the "Mid-Cities" into the heart of Big D.
Why the Distance From Arlington TX to Dallas TX Feels Longer Than It Is
The Metroplex is basically one giant, continuous urban sprawl. You never actually leave "the city" when you drive between these two points; you just pass through different versions of it. You leave Arlington, clip the edge of Grand Prairie, maybe brush past Irving, and suddenly you’re staring at the Dallas skyline.
Traffic is the great equalizer here.

The I-30 Gauntlet
Most people default to Interstate 30. It’s the most direct shot. It takes you right past Six Flags Over Texas and the baseball stadium. On a Sunday morning at 7:00 AM? You’ll cruise that 20-mile stretch in about 22 to 25 minutes. You’re a hero. You’re winning at life.
Try that same drive at 5:15 PM on a Tuesday.
Suddenly, that 20-mile gap transforms into a 55-minute crawl. The "Tom Landry Freeway" section of I-30 is notorious for bunching up right around the President George Bush Turnpike interchange and again as you approach the Canyon in downtown Dallas.
The I-20 "Alternative"
Then there’s the southern route. Taking I-20 is technically longer in terms of mileage—usually around 28 to 30 miles depending on where in Arlington you start. However, if I-30 is a parking lot due to a wreck near Six Flags, the I-20 to I-35E north route can actually be faster. It’s a gamble, though. I-20 has its own brand of chaos, mostly involving a lot more long-haul semi-trucks than the commuter-heavy I-30.
When Should You Actually Make the Drive?
If you have a choice, timing is everything. Locals know the "sweet spots."

- The Morning Window: If you aren't on the road by 6:45 AM, just wait until 9:15 AM. Anything in between is just asking for a headache.
- The Mid-Day Oasis: 10:00 AM to 2:00 PM is usually the golden era. The roads are clear, the sun is high, and you can actually use your cruise control.
- The Evening Trap: From 3:30 PM until 7:00 PM, the distance from Arlington TX to Dallas TX effectively doubles.
- Late Night: After 9:00 PM, it’s a breeze, assuming there isn't major roadwork. North Texas loves its nighttime construction.
Can You Get There Without a Car?
This is the part that surprises visitors. Arlington is famously one of the largest cities in America without a comprehensive municipal bus system. So, if you're thinking you'll just hop on a city bus in Arlington to get to Dallas, you’re out of luck.
But you aren't totally stranded.
The Trinity Railway Express (TRE) is the regional commuter rail. The catch? The stations aren't exactly in the middle of Arlington. The closest stop is the CentrePort/DFW Airport Station, which is technically just north of Arlington. You’ll need an Uber or a Lyft to get from your spot in Arlington to that station. From there, the train takes about 30 to 35 minutes to reach Union Station in downtown Dallas.
It’s a great way to skip the I-30 stress, especially if you’re heading to a Dallas Mavericks or Stars game at the American Airlines Center.

The Cost of the Trip
Basically, unless you’re taking the toll lanes, the drive is "free" in terms of road usage. But North Texas has been leaning hard into TEXpress Lanes. These are managed toll lanes that run down the middle of I-30.
The prices for these lanes fluctuate based on how much traffic is in the "free" lanes. I’ve seen the price to go from Arlington to Dallas jump from $2.00 to over $10.00 during a particularly nasty rush hour. Is it worth $10 to save 15 minutes? On some days, absolutely. Just make sure you have a TollTag (NTTA) or a NorthTexas Tollway Authority account, or they’ll mail you a bill that’s significantly higher.
Surprising Stops Along the Way
Most people just floor it and hope for the best, but there are actually some cool spots if you want to break up the 20-mile journey.
- Lone Star Park: If it’s horse racing season, this is a fun detour in Grand Prairie.
- EpicCentral: A massive new entertainment hub in Grand Prairie with restaurants and a huge indoor waterpark. It’s right off the route.
- The Texas Air & Space Museum: Tucked away near the Arlington/Grand Prairie border, it’s a hidden gem for history buffs.
Making the Trip Work for You
If you're moving here or just visiting, don't let the 20-mile distance fool you into thinking it's a neighborhood hop. Treat it like a mini road trip. Check Waze or Google Maps before you even put your shoes on. In the DFW area, a single stalled car on the shoulder can add twenty minutes to your commute in the blink of an eye.
Also, watch out for the "mixmaster" as you enter Dallas. It’s a dizzying tangle of ramps where I-30, I-35E, and various downtown exits all collide. Get in your lane early. If you miss your exit in downtown Dallas, you might end up halfway to Oklahoma before you find a place to turn around. Kinda kidding. Sorta.
Actionable Next Steps for Your Journey
- Download the GoPass App: If you plan on using the TRE train or DART in Dallas, this app is your lifeline for tickets and schedules.
- Check the NTTA Website: If you’re driving a rental, see how they handle TollTags. Some rental companies charge a fortune in "convenience fees" for tolls.
- Monitor I-30 Construction: The Texas Department of Transportation (TxDOT) is almost always working on something. Check DriveTexas.org for real-time closures before you leave Arlington.
- Plan Around Events: If the Cowboys are playing at home or there’s a massive concert at AT&T Stadium, the traffic flow between Arlington and Dallas flips. Stay away from the Stadium District three hours before and two hours after any major event.
The distance from Arlington TX to Dallas TX is short on paper but long on character. Give yourself a 45-minute buffer, keep your maps app open, and you'll survive the trek just fine.
