MoDOT installs temporary barriers on MO-367 to reduce crashes, speeding
Safety demonstration precedes $10 million permanent improvement project
NORTH ST. LOUIS COUNTY (First Alert 4) - The Missouri Department of Transportation is installing temporary traffic barriers on Missouri Highway 367 southbound starting Wednesday to reduce crashes and excessive speeding on a stretch of highway that has claimed 29 lives since 2018.

The barriers will reduce southbound Highway 367 to one lane from just south of I-270 to Comet Drive.
What the demonstration is designed to do
“The demonstration is designed to reduce crashes and excessive speeding, as well as allow us to collect that real-world data in order to see how the changes impact traffic flow from the north near the I-270 interchange into the neighborhoods along MO-367,” said Tabitha Locke, North St. Louis County MODOT engineer.
MoDOT said the corridor has been on its radar since 2018. The safety demonstration is intended to pave the way for a $10 million permanent improvement project that could include narrowed lanes, curb extensions and better lighting.
Why it took until 2026
When asked why safety changes took this long on a known problem corridor, MoDOT said a roadway study was conducted in 2024, which included a five-year crash study covering 2018-2024.
“As we are getting closer, we have more updated data as well as some extra speed studies in order to make sure what we are implementing with the long-term safety project is the appropriate measures,” Locke said.
The temporary traffic barriers will remain in place until work on the permanent fix begins in the summer of 2027.
