Lane report: Dallas → Laredo, spring 2026

If you run Texas, you already know I-35 South is one of the most-watched lanes in the country. Dallas → Laredo isn't just a 440-mile run — it's the U.S. half of the busiest commercial border crossing in North America, and the way it prices in March through May is its own little ecosystem. This is what spring 2026 actually looks like from the desk.

The short version: southbound dry van is running $1.85–$2.25/mi linehaul, northbound back through DFW is $2.30–$2.80/mi if you grab the right produce or maquiladora freight, and the difference between a good week and a flat one on this lane is whether you understood how Tuesday afternoons price.

I've booked this lane for the better part of three years. Below is what I'd tell a carrier sitting in DFW on a Sunday night this April.

The lane in one paragraph

Dallas to Laredo via I-35 South is about 440 miles one-way, 6.5 to 7 hours of straight drive time, with most of the time-killer at the south end — Laredo cross-docks, the World Trade Bridge truck queue, and CBP. Northbound it's the same road, but the freight character flips. South pulls retail replenishment, automotive parts feeding maquiladora plants in northern Mexico, and a steady drumbeat of empty trailer reposition moves. North pulls produce, finished maquiladora goods, and a chunk of cross-docked LTL.

Spot rates, both directions, spring 2026

Pulled from the DAT regional read and what we've actually been booking on the desk:

These are ranges, not single points, on purpose. I will not give you a $2.07/mi number that pretends to be precise. Anyone who does is selling you something.

Why northbound pays more (and when it stops)

From early March through about Memorial Day, produce coming north out of Mexico dominates this lane. Tomatoes, peppers, berries, avocados — it all flows through Laredo, gets cross-docked or handed off to U.S. carriers, and pushes north. The reefer side of that pool is its own conversation; we wrote a produce season rate forecast for that. But even dry van benefits from the spillover, because every reefer pulled into Laredo means a dry-van slot opened on a different lane.

Once you hit June, the produce ramp falls off, and northbound rates compress back into a 5–8% premium over southbound — not the 15–25% you can see in April.

The Tuesday-after-cutoff pattern

Here's a thing dispatchers know that drivers sometimes don't: Dallas-area produce receivers cut off Monday delivery appointments early in the week. That means the freight that needed to be in Dallas on Monday but didn't get covered piles up into Tuesday. By Tuesday at 10 AM, brokers are paying premiums to cover Wednesday border pickups.

If you're sitting in DFW Sunday night with no booked load, do not panic-book Monday morning at the floor rate. Hold to Tuesday lunch and you'll typically clear $0.15–$0.22/mi more on the same equipment.

The opposite is true on Fridays. Friday afternoon Laredo loads going anywhere are the worst-priced of the week — brokers know carriers don't want to sit at the border over the weekend, and they price accordingly.

The broker pool — categories, not names

I'm not going to put broker names in print. But the pool you want to be on the phone with on this lane breaks down like this:

• Cross-border desks at the top-15 3PLs. They handle the maquiladora and automotive customers and price honestly because they have to keep up with their own contract rates.
• Mexico-focused mid-market brokers — the ones with offices in Laredo, McAllen, or Monterrey. They know the cross-dock partners and they price the lane with realistic deadhead in the rate.
• Produce-specialist brokers for the March–May window. Different rolodex, different pace; they want carriers who will commit a week ahead.

Brokers to be cautious of: anyone posting a Friday 4 PM Laredo southbound at $1.55/mi all-in. That's a load that's been in the system since Monday and nobody touched it for a reason.

Border wait, FAST/CTPAT, and the cross-dock decision

Most U.S. carriers don't cross the border. You drop at a Laredo cross-dock, a Mexican carrier picks it up, and vice versa for northbound. That's fine — it's how the lane is built. The advantage is no FAST/CTPAT paperwork, no Mexican insurance, no commercial driver complications.

If you're seriously running this lane and crossing 4+ times a month, then FAST/CTPAT starts to make sense. CBP wait times publish hourly, and FAST-lane access at World Trade Bridge can shave a couple of hours off a bad day. Below that volume, the program enrollment cost and audit overhead doesn't pay back.

A note on rail: CPKC (the merger of KCS into CP) has pulled a real chunk of long-haul DFW-to-interior-Mexico freight off truckload and onto intermodal. That's why the long DFW → Monterrey or DFW → San Luis Potosí truckload pool feels thinner than it did three years ago. The truck-friendly freight on this lane is now mostly the regional shuttle — DFW down to Laredo, hand off, repeat.

The bottom line on Dallas–Laredo this spring

If you can stage your week to leave DFW on Tuesday morning, drop in Laredo by Tuesday night, and pick up a northbound load Wednesday morning, you'll average $2.40–$2.65/mi all-in across the round trip — which is a healthy spring quarter on a 440-mile shuttle. If you let Friday afternoon dictate your week, you'll average closer to $1.95/mi all-in and you'll wonder where the lane went.

This is exactly the kind of lane our desk lives in — short cycle, repeatable, with a clear premium for getting the timing right.
