Dallas to Houston Heavy Equipment Shipping Guide
The Dallas-to-Houston corridor on Interstate 45 is one of the highest-volume heavy-haul lanes in the United States, spanning approximately 240 miles through the heart of Texas. With major auction yards, equipment dealers, and construction projects concentrated in both metro areas, this lane sees constant movement of excavators, cranes, dozers, and industrial machinery. Knowing the TxDOT permit process, trailer requirements, and Houston-area delivery logistics keeps your move on schedule.
Route Overview: Dallas to Houston via I-45
Interstate 45 South is the direct, primary route connecting Dallas and Houston — approximately 239–240 miles with transit times of 3.5–4 hours under normal conditions. The highway passes through Ennis, Corsicana, Fairfield, Huntsville, and Conroe before entering the Houston metro. For heavy-haul loads, actual transit time is longer due to permitted travel windows, escort coordination, and urban delivery logistics in Houston.
Texas Oversize/Overweight Permit Requirements
Texas Department of Transportation (TxDOT) issues oversize and overweight permits through its online ePERMIT system. Key thresholds:
- Width: Over 8.5 ft requires a permit; over 14 ft requires a route survey and may require utility coordination
- Height: Over 14 ft requires a permit; over 17 ft requires a route survey
- Weight: Over 80,000 lbs GVW requires a permit; loads over 254,300 lbs are classified as superloads requiring engineering review
- Length: Over 65 ft (single vehicle) or 85 ft (combination) requires a permit
- Travel restrictions: Oversize loads may not travel during peak hours in Dallas and Houston metro areas (typically 7–9 AM and 4–6 PM weekdays). Night travel restrictions apply for loads over 14 ft wide.
Trailer Options for Dallas–Houston Moves
| Equipment | Trailer Type | Typical Weight Range |
|---|---|---|
| Mini excavators, skid steers | Flatbed or step deck | 6,000–18,000 lbs |
| Mid-size excavators (20–40 ton) | Lowboy or RGN | 44,000–88,000 lbs |
| Large dozers, motor graders | RGN lowboy | 50,000–120,000 lbs |
| Cranes (boom sections) | Multiple flatbeds | Varies by model |
| Industrial generators | Step deck or lowboy | 20,000–80,000 lbs |
Houston Metro Delivery Considerations
Houston is a sprawling metro with significant variation in delivery site conditions. Port of Houston deliveries (for export-bound equipment) require coordination with terminal operators and may involve drayage from a staging yard. Urban construction sites in downtown Houston often have limited staging space and may require police escorts for wide loads on city streets. The Sam Houston Tollway and Hardy Toll Road are common approaches to the port area — ensure your carrier has a TxTag or payment method for toll sections.
Flooding Risk on I-45
The I-45 corridor near Houston is prone to flooding, particularly between Conroe and the Houston metro. During hurricane season (June–November) and after heavy rain events, sections of I-45 can close with little warning. Carriers should monitor TxDOT's DriveTexas portal for real-time road conditions. For time-sensitive moves, having an alternate routing plan via US-59 or I-10 is advisable.
Cost Factors on the Dallas–Houston Lane
- Base linehaul: $2.50–$4.50/mile for standard lowboy moves on this short corridor
- TxDOT permits: Single-trip permits typically $30–$200 depending on dimensions and weight
- Escort vehicles: Required for loads over 14 ft wide; $3–$5/mile per pilot car
- Fuel surcharges: Adjusted weekly per DOE diesel index
- Minimum charges: Most carriers apply a minimum load charge on short corridors like this one

Common questions
How long does it take to ship heavy equipment from Dallas to Houston?
The drive is approximately 240 miles via I-45. For permitted heavy-haul loads, plan for 1–2 transit days accounting for permitted travel windows, urban delivery logistics, and potential weather delays near Houston.
What permits are needed to ship heavy equipment in Texas?
TxDOT issues oversize/overweight permits via its ePERMIT system. Any load over 80,000 lbs GVW, 8.5 ft wide, 14 ft tall, or 65 ft long requires a permit. Superloads over 254,300 lbs require engineering review.
Can I ship equipment to the Port of Houston from Dallas?
Yes. IronHaul regularly moves equipment from Dallas-area auction yards and dealers to the Port of Houston for export. We coordinate with terminal operators and handle all TxDOT permits and escort requirements.
What trailer is used to ship a large excavator from Dallas to Houston?
Large excavators (20–50 ton) are typically transported on RGN (removable gooseneck) lowboy trailers. The RGN allows the machine to drive on under its own power, which is faster and safer than crane loading.
Is flooding a concern for heavy haul trucks on I-45 near Houston?
Yes. The I-45 corridor near Houston is prone to flooding during hurricane season (June–November) and after heavy rain. Carriers monitor TxDOT's DriveTexas portal and may reroute via US-59 or I-10 when I-45 is affected.
