Running Freight Through Missouri
Major Freight Crossroads
I-70 connects St. Louis and Kansas City directly across the state, while I-44, I-55, and I-29 add further corridors, making Missouri a common through-state for freight moving in nearly every direction across the country.
Twin Distribution Hubs
Both St. Louis and Kansas City serve as significant Midwest distribution hubs, generating steady freight volume on either end of the state and giving Missouri two separate metro areas carriers plan routes and layovers around.
Ozark Terrain in the South
Southern Missouri's Ozark hills bring genuine elevation change and winding roads that contrast with the flatter terrain across most of the state, particularly for carriers running routes through Springfield and the southern counties.
IFTA and Trucking in Missouri: What to Know
Missouri sits at a genuine freight crossroads, with I-70 running east to west between St. Louis and Kansas City and I-44, I-55, and I-29 adding major north-south and diagonal routes through the state. Both St. Louis and Kansas City function as significant distribution hubs, and the Missouri and Mississippi Rivers cross the state's major corridors at several points. The Ozark hills in the southern part of the state add some of the only real elevation change in an otherwise fairly flat Midwest landscape.
IFTA Filing for Missouri Miles
Missouri participates in IFTA like every other member jurisdiction, so a carrier based outside the state reports Missouri miles and Missouri fuel purchases through their regular quarterly return filed with their base state, with no separate Missouri filing required.
Because I-70 carries such heavy volume of through freight between St. Louis and Kansas City, a lot of carriers rack up meaningful Missouri mileage even on trips that neither start nor end in the state, so keeping accurate trip logs for pass-through miles matters as much here as anywhere.
Weigh Stations and Enforcement
The Missouri State Highway Patrol and Missouri DOT operate weigh stations along I-70, I-44, I-55, and I-29, with particularly active enforcement near the state's numerous river crossings and both major metro areas. Carriers running the state regularly should keep documentation current given the consistent presence along these corridors.
Permits and River Crossings
Missouri DOT issues oversize and overweight permits for freight exceeding standard limits, and the state's numerous Missouri and Mississippi River crossings occasionally carry weight or route restrictions worth confirming ahead of time. Carriers running oversize loads through the state should check bridge and route approvals before committing to a path, particularly around the St. Louis metro area.
Weather and Seasonal Planning
Missouri sits squarely on the eastern edge of Tornado Alley, and spring brings an active severe thunderstorm and tornado season that carriers running the state should watch closely, particularly across the flatter northern and western parts of the state.
Winter brings occasional ice storms and snow, especially across the northern half of the state, while the Ozark region in the south sees somewhat milder winters but its hills and curves demand extra caution regardless of season. Summer heat and humidity round out a fairly typical Midwest weather year.
Carriers Running Missouri Freight
“I run I-70 between St. Louis and Kansas City so often it barely feels like a trip anymore. Missouri is about as central as trucking gets.”
“The Ozark hills south of Springfield are the one part of Missouri that actually makes you pay attention to the road. Everywhere else is pretty flat and easy.”
