Roughly 260 miles and four hours of driving, with the two worst traffic problems in Texas sitting at either end. The middle three hours are straightforward. The first and last forty-five minutes are where the trip is won or lost. DFW hub: Dallas to Fort Worth traffic guide. Why I-20 often wins at the north end: fastest route Dallas to Fort Worth.
The short answer
- Distance: ~260 miles
- Free-flow drive time: about 3 hours 50 minutes
- Realistic time with peaks: 4.5 to 5 hours if you hit either metro at rush hour. Pattern estimates, not measured figures for today.
- Best departure from Houston: before 6:00 a.m. or 9:30 a.m.–noon
- Worst departure: 3:00–6:00 p.m.
Why the ends matter more than the middle
Houston–The Woodlands–Sugar Land holds 36 of the state's 100 most congested road segments, and Dallas–Fort Worth holds 41. Between them, the two metros account for more than three quarters of the entire list (TxDOT Top 100; Dallas Morning News).
The state's single most congested segment is the West Loop, I-610, in Harris County — first for the third consecutive year, generating an annual congestion cost of about $166 million and roughly 1.73 million hours of delay. Second is the Eastex Freeway, I-69/US 59, also in Harris County. At the other end, I-35W between SH 183 and I-30 in Fort Worth appears on the same list. Houston-end windows: best time to leave in Houston.
Route options
I-45 to I-20 west — the interstate route
North on I-45 through Huntsville and Corsicana, then west on I-20 past the southern Metroplex into Fort Worth. ~265 miles, ~3 hr 55 min free-flow. Best for most trips, especially arriving during a DFW peak. Approaching Fort Worth on I-20 keeps you out of I-30 and Arlington entirely.
US 290 to SH 6 / US 287 — the northwest diagonal
Northwest through Brenham and Waco before joining US 287 into Fort Worth. ~255 miles, ~4 hr free-flow. Best off-peak, for smaller roads, or Brazos Valley stops. Slightly shorter, comparable in time, less consistent speed and fewer services.
I-45 to I-35E — the Dallas approach
North on I-45 into Dallas, then west. Best only if you have a Dallas stop. If Fort Worth is the destination, I-20 is almost always the better ending.
Timing the trip
| Leave Houston | Arrive Fort Worth | Verdict |
|---|---|---|
| Before 6:00 a.m. | ~10:00 a.m. | Best. Clears Houston, arrives DFW midday. |
| 9:30 a.m.–noon | 1:30–4:00 p.m. | Good. Both metros off-peak. |
| 1:00–2:30 p.m. | 5:00–6:30 p.m. | Poor. Arrives into the DFW evening peak. |
| 3:00–6:00 p.m. | 7:00–10:00 p.m. | Worst. Houston outbound plus a long evening drive. |
| After 7:00 p.m. | 11:00 p.m. + | Clear roads, night arrival. |
The DFW evening peak between 4:00 and 6:30 p.m. can add half an hour to a trip that was going fine for three and a half hours.
Stops along the way
Huntsville — about an hour out of Houston. Madisonville / Buffalo — I-45 midpoint. Corsicana — last easy stop before metro traffic. Waco — midpoint on the US 290 / US 287 routing. A 20-minute break at Buffalo or Waco is often the cheapest way to shift your DFW arrival out of the evening peak.
Weather on this route
Spring convective storms are the main risk, often late afternoon — the same window as the worst arrival timing. Crosswinds between Huntsville and Corsicana affect high-profile vehicles. Fog is a real hazard on rural stretches in the early morning, particularly in the Brazos Valley. See does rain make traffic worse.

On a four-hour drive the departure decision is made once. BoardSpy models Houston's outbound peak, the open middle, and your DFW arrival, with live weather along the full route rather than just at the endpoints.
Frequently asked questions
How long does it take to drive from Houston to Fort Worth?
About 260 miles. Free-flow is roughly 3 hours 50 minutes. If you hit rush hour at either end, plan on 4.5 to 5 hours.
What is the best time to leave Houston for Fort Worth?
Before 6:00 a.m., or 9:30 a.m. to noon. Avoid 3:00–6:00 p.m., which stacks Houston's outbound peak with a DFW evening arrival.
Should I take I-45 to I-20 or go through Dallas?
Finish on I-20 west into Fort Worth. I-45 all the way into Dallas then west puts you through the most congested part of the Metroplex. Use the Dallas approach only if you have a Dallas stop.
Is the US 290 / US 287 diagonal faster?
Slightly shorter (~255 miles) and comparable in time off-peak, with a more pleasant Brazos Valley run. Less consistent speed and fewer services than I-45/I-20.
Where should I stop?
Buffalo or Madisonville on I-45, or Waco on the northwest diagonal. A 20-minute midpoint stop is often the cheapest way to miss DFW's 4:00–6:30 p.m. peak.
