Trucking in Missouri

Missouri is a crossroads state. Kansas City and St. Louis sit at opposite ends of I-70, and between them runs 251 miles of the busiest freight corridor in the heartland — currently being expanded from four to six lanes in a $3 billion project that will reshape the drive through 2028 and beyond. I-44 angles from the Oklahoma border through Springfield to St. Louis. I-55 follows the Mississippi River from Illinois to Arkansas. I-35 drops south from Iowa to Kansas City. Every major freight route in the central US touches Missouri.

Missouri has no toll roads, and that is not an accident — state law prohibits them. Voters rejected tolling in 1970 and again in 1992. Every interstate and highway is free. That is a real operating cost advantage, especially compared to the Kansas Turnpike to the west and Illinois tolls to the east. When I-44 crosses into Oklahoma, the toll booths appear. In Missouri, they do not. Missouri also has no weight-distance tax, no state fuel tax surcharge beyond the standard per-gallon rate, and no mandatory chain law — the regulatory cost of operating here is among the lowest in the Midwest.

The freight economy reflects the crossroads position. Kansas City is a major intermodal hub where rail and truck freight converge, with large distribution centers and cold storage facilities concentrated in the I-435 corridor. Automotive manufacturing, agriculture, and food processing drive outbound freight throughout the state. St. Louis handles significant river barge-to-truck transfers along the Mississippi, particularly grain moving downriver and steel and chemicals moving inland. The corridor between the two cities on I-70 carries some of the densest freight traffic in the Midwest — and with the ongoing widening project, lane closures and shifting traffic patterns are a daily reality through at least 2028. Check MoDOT’s Traveler Information Map before every I-70 run.

Non-Interstate highways allow higher axle weights: 22,000 lb single and 36,000 lb tandem, compared to the standard 20,000/34,000 on Interstates. Height clearance runs 14 feet (up to 15 feet in commercial zones), which is more generous than most states. The truck parking situation on I-70 is severe — all public rest areas and roughly 75% of truck stops hit capacity by early evening. Concordia, Boonville, and Wright City rest areas routinely fill after 6 PM. Along I-44 through the Ozarks, parking thins out between Springfield and St. Louis. Drivers running I-70 at night should plan stops well before dark — circling for parking at 10 PM on the Kansas City-to-St. Louis run is a common and avoidable headache.

The Ozarks region along I-44 and US-65 south of Springfield presents rolling hills, winding roads, and fog in the river valleys. The terrain is not extreme like the Appalachian mountains, but it catches drivers off guard — especially those used to the flat I-70 corridor. Grades are moderate but sustained, and two-lane state highways through the Ozarks are not truck-friendly in winter. The Lake of the Ozarks area generates recreational traffic that spikes on summer weekends, adding congestion on routes that are already narrow. Springfield serves as the regional freight hub for the Ozarks, and the I-44/US-65 interchange is a major distribution point for southern Missouri and northern Arkansas.

Missouri weather brings a mix of hazards through the year. Ice storms are the primary winter danger, particularly on I-70 between Kansas City and Columbia where freezing rain can coat roads faster than MoDOT can treat them. The Ozarks along I-44 see ice and snow accumulation from November through March. Summer brings severe thunderstorms with high winds, hail, and occasional tornadoes — Missouri sits squarely in tornado alley, and the I-44 corridor through Joplin has experienced devastating storms. Flash flooding hits the river valleys and low-water crossings on secondary roads, mainly during spring and early summer. MoDOT’s seven major weigh stations are spread across the Interstate system, and all commercial vehicles at 18,001 lbs and above must enter when stations are open. PrePass and Drivewyze bypass enrollment saves time on regular runs.

Fuel availability is strong throughout Missouri, with competitive truck stop pricing along all four major interstates. The I-70 corridor between Kansas City and St. Louis has frequent fuel and service options. I-44 through the Ozarks has adequate stops but with wider spacing between Springfield and Rolla. Diesel prices in Missouri typically run below the national average, which is another operating cost advantage for carriers based here or running regular routes through the state.

The Kansas City and St. Louis metro areas each present distinct driving challenges. Kansas City’s I-435 loop carries heavy truck traffic, and the I-70/I-435 interchange on the east side is a frequent congestion point. The Buck O’Neil Bridge replacement and other infrastructure projects in the KC metro add construction zones that shift regularly. In St. Louis, the I-70/I-44/I-55/I-64 interchange complex near downtown — known locally as the mixing bowl — funnels an enormous volume of truck traffic through a tight area. The Poplar Street Bridge carries I-55/I-64 across the Mississippi into Illinois and is a persistent bottleneck. Drivers unfamiliar with St. Louis should study the interchange patterns before entering the metro, because lane positioning decisions happen fast and missed exits cost miles.

Missouri is tort-based with no PIP requirement. Insurance rates run moderate, generally lower than Illinois and comparable to Indiana. The state’s central location means most Missouri-based carriers are running multi-state operations, which adds exposure across jurisdictions. Intrastate carriers need state minimums of $25,000/$50,000/$25,000, while intrastate property-hazardous carriers operating vehicles over 10,000 lbs GVWR must carry $1,000,000 minimum. The MoDOT Carrier Express portal handles intrastate authority applications, OSOW permits, and insurance filings online. Annual regulatory decals run $10 per vehicle. RMS recommends $1,000,000 CSL for all Missouri operations — the combination of heavy I-70 traffic, ice storm exposure, and multi-state routing makes adequate coverage non-negotiable.
