A pedestrian died early Sunday morning after being struck by a semitruck on the Interstate 70 ramp to Route W in Foristell, in western St. Charles County, according to the Missouri State Highway Patrol. The pedestrian was pronounced dead at the scene.
The crash shut down westbound I-70 near Missouri Routes W and T, according to fox2now.com, which reported that one pedestrian died at the scene. The station attributed its account to the Missouri State Highway Patrol, which did not disclose the victim's name, age or gender. STLtoday.com, however, identified the pedestrian as 18 years old. The Missouri Highway Patrol, as a matter of policy, does not release the names of accident victims.
Accounts of the crash time differ. Fox 2 placed it around 4 or 5 a.m. Sunday, while a separate report from firstalert4.com said MoDOT indicated the incident took place around 5:45 a.m. Lanes on westbound I-70 have since reopened, the station reported, after the highway was closed following the crash.
A Stretch of Highway Under Construction
The Foristell interchange where the crash happened sits within a broader stretch of I-70 undergoing major reconstruction. The Missouri Department of Transportation's Improve I-70: Warrenton to Wentzville project is a $600 million design-build effort covering 20 miles of highway between the two towns, according to the agency. Construction on the full project is not expected to wrap up until the end of 2028, per MoDOT.
Not the First Pedestrian Struck Near Foristell
Sunday's fatality adds to a string of pedestrian and cyclist crashes along this same corridor over the past year. In December 2025, a bicyclist was struck by a semitruck on eastbound I-70 at Foristell in the late afternoon, according to firstalert4.com. In August, a report from ksdk.com described a 23-year-old man who walked in front of a truck and was struck on eastbound I-70.
No further details on the circumstances of Sunday's crash, including what the pedestrian was doing on the ramp before being struck, have been released by investigators.
