UPDATE ON ROUTE 340 (CLARKSON ROAD) and ROUTE CC (LONG ROAD): MoDOT to remove curb bump out islands along Routes 340 and CC | Missouri Department of Transportation
In the St. Louis are, there were 5, 321 crashes where at least one person was killed or seriously injured between 2016 and 2020. MoDOT's goal, in partnership with St. Louis County, is to reduce those fatal and serious injury crashes in St. Louis.
This project spans across the city of St. Louis, St. Louis County, and Jefferson County.
Our project is estimated to reduce over 170 fatal and serious crashes over a 10-year period.
The Safety Improvements Project will benefit pedestrians and other roadway users at more than 230 locations. Each location may have one or more (up to five) safety improvements. The following locations have been highlighted as locations with significantly visual safety improvements:
Southwest St. Louis County
Clarkson Road (MO 340):
Raised Median Islands
Curved Warning Signs
Retro-reflective signal backplates
Improved right-turn angles
Leading pedestrian interval
High-visibility crosswalks
More about Traffic Calming Islands: Speeding drivers are more likely to cause a crash, and those crashes are more likely to be severe. Studies show that drivers will drive more slowly on narrower roads. Encouraging slower driving (called “traffic calming”) reduces the frequency and severity of crashes.
Long Road (Route CC)
Raised Median Island
Retro-reflective signal backplates
North St. Louis County
New Halls Ferry (Route AC)
Raised median island
Chevrons signs on curve
Leading Pedestrian Intervals
High-visibility cross walks
Retroflective signal backplates
ADA curb ramps
Offset left turn lanes
Improved right turn angle
Hardened centerline
