Austin to Dallas freight: I-35 timing, traffic and DFW docks

A morning pickup in Austin usually delivers in Dallas the same day. Getting the truck back the same day depends on two docks, a 14-hour clock, and whether your dock sits north or south of central Austin, where I-35 carries the highest truck congestion cost in Texas: $40.2 million a year.

How long does Austin to Dallas freight take?

Austin to Dallas freight runs about 185 to 220 routed miles, depending on where the load starts and which side of the Metroplex it delivers to. At a 45 mph planning average, that's 4 to 5 hours of driving, so a morning pickup usually delivers the same day. One driver can even run it there and back in a day, but only when both docks are quick: the 14-hour duty window leaves roughly 4 to 5.5 hours for loading, unloading and traffic.

Key points

  • From north Austin, it's about 190 routed miles to downtown Dallas, 187 to the Southern Dallas County Inland Port, 184 to downtown Fort Worth and 201 to AllianceTexas.
  • Start in Buda instead, and each trip runs about 20 miles longer and crosses central Austin's I-35, the road segment with the highest truck congestion cost in Texas.
  • Truck traffic is heavier between the cities than in them: about 32,400 a day on I-35 in south Waco in 2025, against 19,100 in central Austin.
  • I-35 through south Waco is down to two lanes each way while TxDOT rebuilds it, and the project is scheduled to finish in early 2029.
  • In Fort Worth, I-35W from SH 183 to I-30 ranks second in Texas for truck congestion. Stemmons Freeway (I-35E) in Dallas ranks 11th.

These are routed miles from a routing service built on OpenStreetMap data, rounded. It plots car routes, so a truck's route can differ by a few miles. The 45 mph average is our own planning assumption for a loaded truck on a corridor this busy, not a promise. Every route runs I-35 to Hillsboro and then splits: I-35E for Dallas and the inland port, I-35W for Fort Worth and Alliance.

Same-day round trip: the hours-of-service math

Federal hours-of-service rules let a property-carrying driver drive up to 11 hours inside a 14-hour window that starts when the driver comes on duty, and require a 30-minute break after 8 hours of driving. The break can be time spent on duty without driving, so 30 minutes at a dock counts. Here's our math for one driver doing a same-day round trip:

Round tripMilesDriving at 45 mphLeft in the 14-hour window
North Austin to downtown Dallas and back3808 h 27 minabout 5 h 30 min
North Austin to AllianceTexas and back4028 h 56 minabout 5 h
Buda to AllianceTexas and back4409 h 47 minabout 4 h 15 min

All three fit under the 11-hour driving limit. The squeeze is the 14-hour window, which keeps running while the truck waits. Whatever's left has to cover the pre-trip inspection, fuel, loading in Austin, unloading in DFW and any traffic worse than our planning average. If each dock takes the two hours of free time that detention terms commonly allow, the turn only works on the shortest trips, with almost nothing to spare. When your customer needs the trailer back the same day, the dock times decide it, not the miles. Our article on detention covers the part of that you control.

Departure time matters for the same reason. A truck that leaves north Austin at 5 AM reaches downtown Dallas around 9:15 at our planning average, just after the weekday morning peak, which TTI measures from 6 to 9 AM. Coming back, a truck that leaves Dallas at 1 PM reaches Austin around 5:15 PM, inside the 4 to 7 PM evening peak. It costs the most time if it has to cross central Austin.

Where the time goes: the I-35 segments that cost trucks most

The Texas A&M Transportation Institute (TTI) ranks the state's most congested road segments every year. Its 2025 list, built on 2024 data, includes these segments on the way from Austin into Dallas and Fort Worth:

SegmentTruck congestion rank in TexasAnnual truck congestion cost
I-35W, SH 183 to I-30, Fort Worth2$22.3 million
I-35, US 290 N to Ben White Blvd, central Austin5$40.2 million
I-35, Ben White Blvd to Slaughter Ln, south Austin9$17.4 million
I-35, Slaughter Ln to SH 45, south Austin10$16.8 million
I-35E (Stemmons Fwy), SH 183 to I-30, Dallas11$20.8 million
I-35W, US 81/287 to NE Loop 820, north Fort Worth18$9.6 million
I-35, Parmer Ln to US 290 N, north Austin43$12.4 million
I-35, RM 1431 to SH 45, Round Rock52$9.2 million

TTI ranks segments by truck delay per mile, so a short, jammed stretch can outrank a longer one that costs more in total. On total cost, the central Austin segment from US 290 to Ben White is the worst on the list: $40.2 million a year in truck congestion, more than any other road segment in Texas. TTI describes some roads as places "where it is always rush hour," and it names I-35 through central Austin as one of them. The two segments south of it joined the truck top 10 in the 2025 report. Across every segment TTI monitors, truck delay rose 16% in 2024.

Your dock's location decides how much of that delay your load sits in. If your dock is in north Austin, Pflugerville or Round Rock, a northbound load skips the worst of it. If your dock is in Buda, Kyle or San Marcos, the load crosses all three of Austin's top-10 truck segments before it reaches US-290.

Construction adds to it. TxDOT's Capital Express projects are rebuilding I-35 across Austin. The south section, from Ben White to SH 45 SE, is scheduled to finish in late 2028, with nightly flyover closures from 9 PM to 6 AM on and off through late 2026. The north section, from SH 45 N to US 290 E, is scheduled for early 2029. The central section, a $4.5 billion rebuild through downtown, runs in stages through 2033. Night moves that dodge the daytime traffic are the ones most likely to meet a closure, so check before a late departure.

Between the cities: Waco and the Hillsboro split

TxDOT's 2025 traffic counts show where the trucks are:

Point on I-35 (2025)Vehicles a dayShare that are trucksTrucks a day
Central Austin187,78310.2%19,101
Round Rock177,67111.1%19,757

I-35E, just north of I-20 in Dallas147,2087.2%10,675

Between the metros, one vehicle in every three or four is a truck, and south Waco carries more trucks than any other count point on the lane. That's where TxDOT is rebuilding I-35 from South Loop 340 to 12th Street and widening it from six lanes to eight. TxDOT said in June 2025 that the work would cut I-35 to two lanes in each direction from late summer 2025 for about two years, and it lists the project for completion in early 2029. The City of Waco notes a 55 mph limit in the work zones. Two lanes each way with that many trucks leaves little room when something goes wrong, so build slack into the schedule.

North of Hillsboro, I-35E carries almost twice the trucks I-35W does: about 18,300 a day against 10,200. On I-35E, truck traffic drops by more than half at I-20, and the inland port sits just south of there, along I-20, I-35E and I-45.

SH 130: when the toll road is worth it

For loads that start south of the river, SH 45 SE and SH 130 are the way around central Austin. Our routing from Buda to downtown Dallas comes out at about 225 miles that way, against 210 on I-35. The tolls are real: at 2026 rates, a five-axle truck with a TxTag pays $8.96 at each of SH 130's four mainline toll plazas and $5.36 on SH 45 SE, about $41 for the full run, or about $62 without a tag before TxDOT's extra fees for non-tag trips.

Whether that's worth it depends on the hour. Outside the peaks, I-35 is shorter and toll-free. In the peaks, central Austin is the costliest stretch of road in Texas for trucks. From north Austin, Pflugerville or Round Rock, the bypass doesn't help, because the truck is already past the worst of it. Ask whether a quote assumes I-35 or SH 130, and whether the tolls are in the rate.

DFW: where the freight is going

Two of the Metroplex's largest freight districts sit at opposite ends of it, on different branches of I-35:

  • AllianceTexas, in north Fort Worth, covers 27,000 acres with 64.7 million square feet developed and 602 companies, according to its February 2026 fact sheet. BNSF's intermodal yard there handles more than a million lifts a year and more than 5,000 trucks a day. It's served by I-35W, SH 114 and SH 170. Allow extra time on the approach: in TTI's list, the I-35W segment from Alliance Gateway to US 81/287 jumped from 477th to 63rd in overall congestion in a single year.
  • The Southern Dallas County Inland Port spans about 7,500 acres across five cities, with more than 25 million square feet occupied, according to the City of Hutchins. Union Pacific's 360-acre intermodal terminal has operated there since 2005, with direct access to I-20, I-35E and I-45.

The large distribution centers in both districts run on appointments, so the delivery appointment sets the departure time from Austin. If the receiver offers drop trailers, the math changes: our drop trailer article covers when that beats a live unload.

Winter on I-35

Ice is the other way this lane goes wrong. On February 11, 2021, TxDOT closed parts of I-35 in Waco because of ice, and the same day a pileup on I-35W in Fort Worth killed six people. In the January 2026 storm, TxDOT reported winter weather on nearly 5,000 roads statewide and used 3.5 million gallons of brine. TxDOT also told Dallas's FOX 4 that brine "significantly diminishes" when temperatures drop below 15 degrees.

When a freeze is in the forecast, decide early whether to ship a day ahead, hold the load or protect it. Beverages, paint and other freeze-sensitive freight can ride in a refrigerated trailer set to heat. TxDOT's DriveTexas map (https://drivetexas.org) is the official source for closures.

FAQ

How long does a truck take from Austin to Dallas?

About 4 to 5 hours of driving for 185 to 220 routed miles, at a 45 mph planning average, plus the time at each dock. A morning pickup usually delivers the same day. These are planning estimates, not promises: traffic, construction and docks set the real number.

Can one driver run Austin to Dallas and back in a day?

On paper, yes. A 380 to 440 mile round trip is about 8.5 to 10 hours of driving, under the 11-hour limit. The 14-hour duty window leaves about 4 to 5.5 hours for both docks, fuel and traffic, so long waits at either end push the return to the next day.

Is SH 130 faster than I-35 for trucks?

From south of Austin it can be. SH 45 SE and SH 130 add about 15 miles from Buda to downtown Dallas and about $41 in tolls for a five-axle truck with a TxTag at 2026 rates, but they skip central Austin's I-35, the costliest truck segment in Texas. From north Austin there's little to gain.

Is Dallas or Fort Worth quicker to reach from Austin?

From north Austin, downtown Fort Worth is a few miles closer than downtown Dallas (184 routed miles against 190), and both are closer than AllianceTexas (201). The bigger difference is the traffic at the end: I-35W from SH 183 to I-30 in Fort Worth ranks second in Texas for truck congestion, and Stemmons Freeway in Dallas ranks 11th.

What happens to Austin to Dallas loads in a winter storm?

I-35 can close: TxDOT shut parts of it in Waco during the February 2021 storm. Check DriveTexas before dispatch, decide early whether to ship ahead or hold, and use a refrigerated trailer set to heat for freeze-sensitive freight.
