Heavy Haul Trucking in Texas, and Every State Your Load Touches

Heavy haul in Texas

The Biggest Heavy Haul Market in the Country

More oversize permits are issued in Texas than in any other state, and it is not close. Oilfield equipment into the Permian and Eagle Ford, refinery and petrochemical modules along the Houston Ship Channel, wind components across the Panhandle and West Texas, and the construction fleet that follows the growth in Dallas, Austin, and San Antonio. If you ship heavy equipment nationally, you ship into Texas.

Texas is also a state where the permit is the easy part and the details get expensive. County road fees stack on top of state overweight permits. Houston and DFW have curfews that eat working hours. Distances are long enough that a one-day move in the Northeast is a two-day move here. A broker quoting Texas off a mileage calculator will miss on all three. Vector Logistics runs Texas lanes on CRST's national network with permits, fees, and curfews priced in before the quote goes out.

The numbers

Legal Limits in Texas

Standard limits on Texas highways. Texas is generous on height and trailer length compared to most states; the complications are weight and fees.

Texas permits are routed: the permit specifies the roads, and the route may not be the one a GPS picks. Deviation without an amended permit is a citation. On long Texas lanes this is where a broker who actually reads the permit saves a driver a bad day.

Permits and escorts

TxDMV Permits and the County Fee Problem

Permits come from the Texas Department of Motor Vehicles Motor Carrier Division through its online system. Routine oversize permits are fast and reasonably priced. The parts that surprise shippers:

• County road fees. Overweight permits in Texas carry additional fees for each county the load crosses on non-Interstate roads. On a long overweight move through rural counties these can exceed the state permit fee several times over. We price them into the quote; a broker who does not will come back with a surprise.
• Curfews. Houston, Dallas-Fort Worth, San Antonio, and Austin restrict oversize movement during weekday peak hours, and larger loads are limited to overnight and weekend windows in Houston. The Ship Channel area has its own scheduling realities with refinery traffic.
• Escorts. Texas thresholds are more generous than the western states: a 12 ft wide load that needs a pilot car in Washington often runs without one in Texas. Over about 14 ft wide, 17 ft tall, or 110 ft long, escorts apply, and height-pole escorts are strict because of the number of low structures on older routes.
• Superheavy. Very heavy loads, typically refinery vessels, transformers, and drilling components, go through a superheavy review with route surveys and bridge analysis. Lead time is weeks, not days.
• Annual permits. Texas offers annual oversize permits for repeat moves within certain dimensions. For fleets shuffling equipment across the state regularly, we set these up.

Roads

Routes and Chokepoints in Texas

I-10, El Paso to the Louisiana line

Nine hundred miles across the state. Open and oversize-friendly in the west, then Houston. Loads staging for a Houston curfew window often sit in Katy or Sealy. East of Houston, the Beaumont refinery corridor and the Sabine crossing.

I-35, Laredo to DFW

The busiest commercial corridor in the state and the NAFTA spine. Congestion through Austin and the San Antonio to Austin stretch is constant, and oversize curfews apply in all three metros. Laredo-originated freight adds border clearance time.

I-45, Houston to Dallas

The Houston to DFW lane carries a lot of construction equipment and petrochem modules. Curfews at both ends; the middle is easy.

I-20 and I-27, the Permian and the Panhandle

Midland, Odessa, Lubbock, Amarillo. Oilfield equipment, wind components, and ag. Long distances, high winds that hold tall loads, and county road fees on the last miles to a lease or a wind site.

US-59 / I-69 and the Gulf Coast

Corpus Christi, Victoria, the Eagle Ford, and Port of Corpus Christi project cargo. Heavy refinery and LNG freight comes out of here, much of it superheavy.

US-287 and the northern route

DFW to Amarillo and on to Colorado. The route most Northwest-to-Texas heavy haul takes through Oklahoma and the Panhandle, and a regular lane for us.

Who ships here

Who Ships Heavy Haul in Texas

• Oil and gas. Drilling rigs, frac equipment, pumps, compressors, and tanks into the Permian, Eagle Ford, and Haynesville, and the pressure vessels and modules that feed the refineries and LNG export terminals on the coast.
• Petrochemical and refining. Houston Ship Channel, Beaumont, Port Arthur, Corpus Christi. Vessels, columns, heat exchangers, and modular units, a large share of them superheavy or super-dimensional.
• Wind and solar. Texas has more wind capacity than any state. Blades, nacelles, and towers through the Panhandle and West Texas, plus solar racking and transformers across the state.
• Construction. DFW, Austin, San Antonio, and Houston are building constantly. Excavators, cranes, pavers, and the rental fleets that support them move between metros daily.
• Semiconductor and data centers. Samsung in Taylor, Texas Instruments in Sherman, and data center builds across the I-35 corridor: transformers, chillers, switchgear, and modular structures.
• Ports. Houston, Corpus Christi, Freeport, Beaumont. Import project cargo that needs heavy haul to the final site, often multiple states away.
• Agriculture. Combines, cotton strippers, and irrigation equipment across the Panhandle, Rio Grande Valley, and Blackland Prairie.

Why Vector

A Broker Who Has Driven These Roads

Texas is where a lot of our Northwest customers' equipment ends up, and where a lot of the nation's heavy haul begins. We quote Texas lanes with the county fees, curfews, and routed permits priced in, and every load runs on CRST's asset-based network with CRST's cargo insurance and compliance behind it. One person accountable, from a Permian lease road to a Portland job site.
