A 23-year-old man from New York was struck and killed by a tractor-trailer on Interstate 70 in Wentzville after midnight Friday, according to the Wentzville Police Department. The pedestrian was pronounced dead at the scene near Wentzville Parkway, where westbound lanes were shut down as investigators worked through the night.
The call came in around 12:30 a.m., as reported by First Alert 4. Westbound I-70 was closed at Wentzville Parkway immediately following the crash and was later reopened once the scene was cleared, the outlet reported. Authorities have not released the man's name or explained why he was walking along the interstate.
A Stretch of Highway Already Squeezed by Construction
Whatever brought the man onto I-70 overnight, he was walking through one of the tightest sections of highway in the region. Missouri Department of Transportation crews broke ground in spring 2025 on a $600 million “Improve I-70” project stretching from Warrenton to Wentzville, aimed at adding a third travel lane in each direction, replacing aging bridges, and reconfiguring interchanges, according to Emery Sapp & Sons, one of the project's contractors.
As of July, MoDOT had installed temporary barrier walls and narrowed lanes to just 11 feet along I-70 between Wentzville Parkway and the Norfolk Southern Railroad bridge, restrictions expected to remain in place through fall, according to the City of Wentzville. That corridor also carries some of the heaviest freight traffic in the state, with the I-70 segment near Wentzville Parkway handling between 45,000 and 75,000 vehicles daily and commercial trucks making up as much as 37 percent of that volume, per data from the Missouri Department of Transportation.
Why Pedestrians End Up on Missouri's Interstates
The circumstances that put someone on foot on a high-speed interstate late at night are often tied to vehicle trouble rather than a deliberate walk along the shoulder. Under MoDOT's “Show-Me Zero” highway safety plan, a significant share of pedestrian fatalities on Missouri interstates involve motorists who had exited a disabled vehicle following a breakdown or earlier crash, rather than people walking along the highway as a matter of course.
State law does address pedestrians on roads without sidewalks. Under Revised Statutes of Missouri Section 300.405, a pedestrian walking along a highway is required, when practicable, to walk only on the left side of the roadway or shoulder, facing oncoming traffic. Separately, Section 300.375 states that no pedestrian may suddenly leave a curb or place of safety and walk or run into the path of a vehicle so close that a driver cannot possibly yield. It remains unknown whether either statute bears on Friday's crash, and no citations or charges against the truck driver have been reported.
A Pattern of Fatal Encounters on the Corridor
This is not the first fatal collision involving a vulnerable road user on this stretch of I-70. In December 2025, a tractor-trailer fatally struck a person riding an electric bicycle on eastbound I-70 near Foristell, just west of Wentzville, after the rider attempted to cross lanes from the shoulder, according to Missouri State Highway Patrol reports cited by KSDK. And back in March 2021, a man in Wentzville was killed on I-70 after walking into traffic from in front of a disabled vehicle stopped in the left lane, KSDK reported at the time, citing police.
The deaths also land amid a broader rise in pedestrian fatalities statewide. Missouri recorded 148 pedestrian deaths in 2024, a 16 percent increase from 2023 and the highest single-year total ever recorded in the state, according to Missouri State Highway Patrol data relayed by KSMU. MoDOT's own vulnerability assessment recorded 139 pedestrian fatalities statewide in 2025, with 70 of those deaths, or roughly half, occurring within the St. Louis regional district that includes Wentzville.
Friday's crash comes weeks after Hoodline reported on a pregnant Wentzville mom's US-61 crash, another serious roadway incident in the same community. No further details on the tractor-trailer driver, the pedestrian's identity, or the events leading up to Friday's crash have been released, and the Wentzville Police Department's investigation remains open.
