Dallas to Nashville is a genuine long-haul drive — about 665 miles and 10 hours, running on just two interstates: I-30 East out of Dallas, then I-40 East the rest of the way once you pick it up in North Little Rock.
You'll leave the Dallas-Fort Worth area on I-30, cross into Arkansas through Texarkana, and continue to Little Rock, where I-30 ends and feeds directly onto I-40 East. From there it's I-40 the whole way — through Memphis, across Tennessee, and into Nashville. At this distance, plenty of people split it into two days rather than pushing straight through.
This isn't a quick weekend hop — it's a full day behind the wheel, or a comfortable two-day drive if you break it up around Little Rock or Memphis. The route itself is simple, with only two interstates involved and no tolls to plan around, so the main planning decision is really just how many days you want to spend on the road.
Plan This Route with Rovo →No. I-30 is toll-free across both Texas and Arkansas, and I-40 has no tolls either — this is a toll-free route start to finish, aside from optional toll lanes in the Dallas-Fort Worth metro area itself if you're navigating around downtown before you get on I-30.
It's possible — about 10 hours of driving — but it's a long single push. A lot of drivers split it into two days with an overnight around Little Rock or Memphis, which keeps each day closer to 5 hours.
Leaving before 6:30am or after 9:30am helps you clear DFW's heavy morning commute on I-30, which is the only real congestion point on an otherwise open route.
