A head-on crash that injured two people on Missouri Route 367 in north St. Louis County occurred just days before MoDOT begins installing temporary concrete median barriers designed to reduce crossover crashes. The incident underscores ongoing safety concerns along one of the region’s most dangerous highway corridors.
BELLEFONTAINE NEIGHBORS, Mo. — Two injured in overnight head-on collision
ST. LOUIS, MO – August 3, 2026 (STL.News) A serious head-on crash on Missouri Route 367 in north St. Louis County has renewed attention to the highway’s longstanding safety issues just days before the Missouri Department of Transportation (MoDOT) launches a temporary safety project intended to reduce severe crossover crashes.
According to authorities, the collision occurred Sunday night near Chambers Road in Bellefontaine Neighbors. Emergency responders found two heavily damaged vehicles after a head-on crash that left one person with serious injuries and another with minor injuries. One of the victims was ejected during the collision. The roadway was closed for several hours while emergency personnel treated the injured, investigated the crash, and cleared the scene.
Investigators have not announced whether criminal charges will be filed. However, reporting indicates the crash occurred following an attempted police traffic stop, and the circumstances remain under investigation. Officials have not released the identities of those involved.
Crash comes just before major Route 367 safety changes
The timing of the collision is particularly significant because MoDOT is scheduled to begin a Route 367 Safety Demonstration Project on Wednesday, Aug. 5.
The project will install temporary concrete median barriers between Interstate 270 and Comet Drive, physically separating northbound and southbound traffic. During the demonstration, traffic will be reduced to one lane in each direction while engineers evaluate whether the changes improve driver safety and reduce severe crashes.
Unlike permanent highway reconstruction, the demonstration project is intended to collect real-world data on how median barriers affect crash rates, driver behavior, and traffic flow before larger, long-term improvements are constructed.
A corridor with a troubling crash history
Route 367 has become one of north St. Louis County’s most closely watched highways because of its history of serious collisions.
Community concern intensified after a May 2026 crash that killed three women near Chambers Road. Following that tragedy, residents called for immediate action, saying excessive speeds and the absence of a physical median contributed to the roadway’s dangers.
In response, MoDOT accelerated several short-term safety initiatives while continuing to develop a broader improvement plan for the corridor.
The temporary barrier project represents the agency’s first significant physical change to the roadway while engineers complete the design of more permanent upgrades.
Speeding remains one of the biggest concerns
Transportation officials say speeding continues to be one of the primary factors contributing to crashes on Route 367.
During recent safety studies, MoDOT found that many motorists routinely exceed the posted speed limit, prompting the department to deploy portable speed-feedback trailers and increase public awareness efforts in cooperation with local law enforcement.
Officials believe physically separating opposing traffic with concrete barriers can dramatically reduce the likelihood of catastrophic head-on collisions, even when speeding or driver error occurs.
Long-term improvements still being developed
The temporary barrier installation is only one component of a broader Route 367 improvement effort.
MoDOT has been conducting an extensive traffic safety and operational study covering the corridor from south of Interstate 270 to north of the Halls Ferry Circle. Engineers have reviewed crash history, traffic volumes, vehicle speeds, and future transportation needs while gathering public input through multiple community meetings. Construction on permanent improvements is currently planned to begin in summer 2027, following completion of design work and property acquisition.
Additional public meetings are scheduled as MoDOT refines its long-term plans for the corridor.
Safety project aims to save lives
Transportation officials acknowledge that the temporary lane reductions may create occasional delays, but they emphasize that preventing fatal and serious-injury crashes is the project’s primary objective.
Concrete median barriers have been used successfully on other highways to eliminate crossover collisions, which often produce the most severe crashes because of the combined speed of vehicles traveling in opposite directions.
By evaluating the demonstration project over the coming year, MoDOT hopes to determine whether similar safety measures should become permanent along Route 367 or be incorporated into future reconstruction plans.
Investigation continues
The investigation into Sunday’s head-on collision remains ongoing, and additional details may be released as investigators complete their review.
For residents who regularly travel Route 367, the crash serves as another reminder of the hazards that have plagued the corridor in recent years. As work begins this week on the temporary median barriers, transportation officials hope the project marks the beginning of meaningful improvements that will reduce serious crashes and make one of north St. Louis County’s busiest highways safer for everyone.
