Local leaders expand St. Louis region’s Slow Down campaign, focusing on West Florissant speeding and crashes
A regionwide push to curb speeding
Local elected officials, community advocates and public-safety leaders are expanding a safer-driving effort in the St. Louis region that targets speeding and reckless driving on corridors with persistent crash concerns, including West Florissant Avenue in North County and North St. Louis.
The initiative, commonly branded as “Slow Down St. Louis,” uses highly visible roadside messaging—yard signs and billboard-style displays—intended to prompt drivers to reduce speed and pay closer attention in neighborhoods where people walking, waiting at bus stops and turning into driveways are exposed to fast-moving traffic.
Why West Florissant is a focal point
West Florissant has been repeatedly identified by regional traffic-safety planners and local governments as a corridor where speeding, crashes and pedestrian risk converge. Community leaders have pointed to the avenue’s role as a major connector between municipalities such as Dellwood and Ferguson, with frequent driveways and crossings that can magnify the consequences of high speeds.
Recent community events tied to the campaign have been held along West Florissant in Ferguson, reflecting a strategy of taking the message directly to streets that residents and officials describe as chronic trouble spots. Organizers have also emphasized that the safety effort is intended to move beyond enforcement alone by encouraging neighborhood-level conversations about everyday driving choices.
What the campaign is doing on the ground
Deploying thousands of “Slow Down” yard signs in residential areas and along high-risk routes.
Placing temporary, high-visibility displays at rotating locations across the metro area, including parts of St. Louis City, St. Louis County and nearby Illinois communities.
Engaging schools and youth-focused partners to reinforce safe-driving norms among new and soon-to-be drivers.
Infrastructure changes also in motion
The campaign is unfolding alongside longer-term roadway efforts intended to reduce crash risk through design. In the City of St. Louis, the “Friendly Streets” framework and adopted traffic-calming guidelines support measures such as road diets, mini-roundabouts and other speed-reducing designs as corridors are resurfaced or rebuilt.
In North County, planning work tied to a “Great Streets” approach for segments of West Florissant has been discussed as a way to slow traffic and improve the corridor’s pedestrian environment through engineering changes rather than messaging alone.
Traffic-safety messaging campaigns can raise awareness quickly, but local officials and planners generally treat engineering, enforcement and behavior change as complementary tools rather than substitutes.
What comes next
Organizers say the “Slow Down” messaging will continue moving to multiple sites across the region. Local governments and transportation agencies are simultaneously advancing corridor redesign and traffic-calming projects intended to deliver measurable, long-term reductions in speed and crash severity.
For residents, the near-term impact will be most visible through signage and rotating displays. The longer-term test will be whether sustained behavior change and infrastructure upgrades can reduce serious injuries and fatalities on corridors where high speeds remain a daily reality.
