Improve I-70 is the largest road project in Missouri history, and the Columbia to Kingdom City segment — $426 million, 20 miles, US 63 to US 54 — is right in the middle of it. Crews started in 2024 and won't finish until late 2027.
Here's what that means for anyone driving it: the shoulder you rely on without thinking about it is gone. Lanes are narrowed. The configuration you drove Monday may be somewhere else by Friday, and muscle memory is exactly what a shifted work zone defeats.
MoDOT's own numbers from 2025: 24 people killed in Missouri work zone crashes. 437 crashes involving a driver who wasn't paying attention. MoDOT's protective vehicles — the trucks built to absorb a hit before it reaches the crews — were struck 50 times, up from 34 the year before.
If you're hurt in one of these, the hard part usually isn't proving you were injured. It's figuring out who to hold responsible. Sometimes it's the other driver. Sometimes it's the contractor, when a sign never went out or a taper was too short or debris didn't get swept. Sometimes it reaches the state, which brings sovereign immunity and damage caps into it. And evidence in these cases — trucking logs, dashcam footage, the work zone configuration itself — does not stay around long.
I wrote a guide walking through each of those, including which claims are realistic and which are hard. Free consultation, no fee unless we win. (573) 499-0200.
