Early Sunday turned tragic on the westbound side of Interstate 64 near Highway K, where a pedestrian was struck and killed by a motorcycle, shutting the highway for hours and tying up the morning drive for countless St. Louis–area commuters. Troopers and emergency crews sealed off all westbound lanes while crash investigators worked through the dark, and traffic quickly spilled onto nearby ramps and surface streets until the scene was cleared.
What Officials Said
According to First Alert 4, the Missouri State Highway Patrol reported that the collision happened at about 2:25 a.m., when a pedestrian was hit by a motorcycle in the westbound lanes. First Alert 4 crews at the scene confirmed that one person had died, and investigators were working to piece together exactly what led up to the impact.
Road Closures And Delays
Westbound I-64 near Highway K stayed shut down for more than three hours while troopers documented the crash site and cleared debris. Drivers were pushed onto surrounding roads, and what is usually a straightforward weekend commute turned into a slow crawl across nearby neighborhoods. By around 6 a.m., crews had reopened the westbound lanes, and traffic gradually started returning to something like normal.
Investigation Underway
Missouri State Highway Patrol troopers are leading the investigation and have not yet released the pedestrian’s name, any information about injuries to the motorcyclist, or whether criminal charges could be in play. Troopers have asked anyone with information or video of the incident to contact investigators. The agency also logs crash details on its public portal; for official records and future updates, visit the Missouri State Highway Patrol.
What Drivers Should Expect
Drivers in the area may still see intermittent slowdowns as follow-up work and crash reviews continue along major corridors. Local officials are urging motorists to build in extra travel time and consider alternate east–west routes until traffic fully stabilizes. Commercial drivers and daily commuters are also being encouraged to keep an eye on traffic apps and official alerts for any additional lane closures tied to the investigation.
