I-35 Truck Trip Planning Guide
Planning notes for I-35 truck trips across central freight markets, wind, storms, and metro areas.
By Dale Connors, Founding Editor · Content reviewed quarterly against FMCSA guidance and official state resources. Corridor overview
I-35 covers roughly 1,570 miles from Laredo, Texas to Duluth, Minnesota, linking the U.S.-Mexico border to the northern Great Plains. The Texas metro chain — San Antonio, Austin, Waco, Dallas/Fort Worth — is one of the most time-consuming freight market sequences on any U.S. highway.
This page is not navigation, route approval, low-clearance routing, hazmat routing, or current weather-based routing. It is a planning framework for deciding what to check before the truck is committed.
Planning segments
| Segment | Why it matters | Planning concern | Conservative planning habit | Source note |
|---|---|---|---|---|
| Texas metro chain | San Antonio, Austin, Waco, DFW, and border-linked freight can compress timing. | Congestion and parking demand can overlap. | Choose stop-before and stop-after options around the metro chain. | Use TxDOT traveler information. |
| Central plains stretches | Wind, storms, and heat can affect open-road planning. | Fuel and fatigue decisions should not wait until late. | Keep a reserve and early parking fallback. | Use NWS wind and severe weather resources. |
| Kansas City / Des Moines / Twin Cities approaches | Metro timing can decide whether the day ends smoothly. | Late arrivals can leave few comfortable choices. | Plan before-market parking and after-market backups. | Use official state traveler resources. |
| Winter and storm transition areas | Conditions can change as the corridor moves north or south. | A plan may be reasonable in one state and poor in the next. | Recheck official conditions at each major stop. | Use NWS and state resources. |
I-35 corridor planning notes
- The Texas metro chain — San Antonio, Austin, Waco, Dallas/Fort Worth — can consume 5 to 6 hours of a driving day, turning a manageable mileage into a late-arrival parking problem.
- DFW is one of the largest freight markets in the country; parking fills early and the stop-before or stop-after decision should be made before the driver reaches Waco.
- Great Plains severe weather (tornadoes, ice storms) is a rapid-onset risk from March through May and in winter; build a stop-before-storm option whenever NWS watches are active.
- Laredo border crossings and Texas agricultural inspection near the Oklahoma line add real time that most schedules underestimate.
HOS and fuel cautions for this corridor
- Texas distances are deceptive — the drive from the southern border to the Oklahoma state line is over 500 miles, and two metro approaches in a single day is common on I-35.
- Oklahoma and Kansas plains wind frequently affects empty and high-profile equipment; elevated fuel reserve is advisable before open stretches during wind advisories.
- Minnesota winter (Twin Cities approach) can compress the day significantly; plan the northern end of the corridor well before snow season.
Late-day decision example
Use this as a dispatch conversation prompt, not as route instruction. The goal is to make the stop-or-continue decision while the driver still has practical choices.
| Setup | Decision point | Conservative move | Dispatcher prompt |
|---|---|---|---|
| A driver approaches a major I-35 metro late in the day after loading, inspection, storm, or fuel delay. | Before entering the metro, decide whether to stop short, cross with a known backup, or adjust the customer ETA. | Do not spend the last useful hour inside a metro approach without a legal parking answer beyond it. | What is the stop-before-market option, and what is the stop-after-market option if traffic is worse than expected? |
Official resources
- Use National Weather Service resources for weather education and alerts.
- Use current state traveler information and carrier-approved truck routing tools for current road, restriction, and closure decisions.
- Use FMCSA and ELD records for HOS decisions.
