Shipping Heavy Equipment from San Antonio, TX to Birmingham, AL
The San Antonio, TX to Birmingham, AL corridor spans approximately 862 miles, running east on I-10 through Houston and Beaumont before connecting to I-20 through Louisiana and Mississippi into Alabama. This route is a workhorse for heavy equipment moves tied to Gulf Coast construction projects, Texas auction pickups, and Alabama industrial sites. IronHaul Logistics coordinates permitted oversize and overweight loads on this lane daily.
Route Overview: San Antonio to Birmingham
The most efficient routing from San Antonio to Birmingham follows I-10 East through Houston (approximately 200 miles), then continues east through Beaumont, TX and into Louisiana before picking up I-20 East through Shreveport, Jackson, MS, and Meridian, MS before entering Alabama. Total driving distance is approximately 862 miles, with typical transit times of 2–3 days for permitted oversize loads that must comply with state-specific travel windows.
States Crossed and Permit Requirements
This lane crosses four states — Texas, Louisiana, Mississippi, and Alabama — each requiring its own oversize/overweight permit. Carriers must obtain individual state permits before departure; no single multi-state permit covers this corridor. Key thresholds that trigger permitting:
- Width over 8.5 ft (102 in): Oversize permit required in all four states
- Height over 13.5 ft: Route survey required; some I-20 overpasses in Mississippi have clearances as low as 14.0 ft
- Gross Vehicle Weight over 80,000 lbs: Overweight permit required; axle weights must comply with the Federal Bridge Formula
- Width over 14 ft: Front and rear escort vehicles required in Texas and Louisiana
Louisiana is known for strict permit enforcement and requires a certified route survey for loads exceeding 16 ft wide or 200,000 lbs GVW. Plan for permit lead times of 2–5 business days per state.
Trailer Selection for This Lane
| Equipment Type | Recommended Trailer | Notes |
|---|---|---|
| Excavators (20–50 ton) | Lowboy or RGN | Deck height 18–24 in keeps total height manageable |
| Bulldozers / Dozers | RGN (Removable Gooseneck) | Drive-on loading; blade must be removed or secured |
| Motor Graders | RGN or Lowboy | Long wheelbase; verify deck length ≥ 29 ft |
| Skid Steers / Compact Equipment | Step Deck or Flatbed | Under 8.5 ft wide; no oversize permit needed |
| Cranes (mobile) | Multi-axle RGN | Counterweights shipped separately; superload permit likely |
Transit Time and Scheduling Considerations
Non-permitted loads (standard flatbed freight) can transit this lane in approximately 13–15 hours of drive time. Oversize loads are subject to daylight-only travel restrictions in Louisiana and Mississippi, which limits daily mileage to roughly 400–500 miles. A typical oversize move on this lane takes 2 transit days plus a loading day, for a total of 3 days from pickup to delivery.
Avoid scheduling moves that would require travel through Louisiana or Mississippi on Friday afternoons or holiday weekends — permit offices close and enforcement is heightened. Spring months (March–May) may also trigger frost law restrictions in Alabama, temporarily reducing allowable axle weights on secondary roads.

Common questions
How long does it take to ship heavy equipment from San Antonio TX to Birmingham AL?
Standard oversize loads typically take 2–3 transit days on this ~862-mile lane. Permit procurement adds 2–5 business days before the move begins. Plan for a total of 5–8 days from booking to delivery for permitted loads.
Do I need oversize permits for every state on the San Antonio to Birmingham route?
Yes. Texas, Louisiana, Mississippi, and Alabama each require their own oversize/overweight permits. There is no single multi-state permit for this corridor. IronHaul handles all permit procurement as part of the transport coordination.
What trailer type is best for shipping an excavator from San Antonio to Birmingham?
A lowboy or RGN (Removable Gooseneck) trailer is standard for excavators in the 20–50 ton class. The low deck height (18–24 inches) keeps total transport height within legal limits across all four states on this route.
Are there travel time restrictions for oversize loads on I-20 through Louisiana and Mississippi?
Yes. Both Louisiana and Mississippi restrict oversize load movement to daylight hours — generally 30 minutes after sunrise to 30 minutes before sunset. Weekend and holiday travel may also be restricted. Your carrier must plan the route accordingly.
