Traffic

The Traffic Division monitors and maintains the City of O’Fallon’s traffic signals and traffic control signs. The Traffic Division also works as project managers for the installation of new signals, signal improvement, and signal modification projects.

Each year, the Traffic Division conducts a preventative maintenance program for the City’s traffic signals, which keeps them safe and working properly.

Because some signals within the City of O’Fallon, such as those on Route K, are not owned or controlled by the City, the Traffic Division notifies the Missouri Department of Transportation (MoDOT) of any requests or concerns regarding the signals. Although it is MoDOT’s responsibility to address the issues, the Traffic Division follows up with MoDOT to see that the issues are addressed properly.  

The Traffic Division also is responsible for the City’s street signs. The Division monitors, replaces and repairs damaged signs, many of which are reported by residents.  

The City of O’Fallon is in the process of changing over the old green street ID signs to a fresh new look to cosmetically spruce up our City, better identify the City’s streets, which is very important for our Police Officers, and make the signs more visible. 

To report any signal malfunctions, damaged or downed signs, request a new sign or report any other incidents, please visit the Citizens First Center or call 636-379-5553. Due to high volume, please allow adequate time for the work to be completed. Requests for new sign installations will be investigated and evaluated based on City Ordinances and National Standards for installation of traffic control devices. 

During after-hours emergencies, please contact the O’Fallon Police Department dispatcher at 636-240-3200.


Citizen’s Speed Monitoring Program

In cities throughout the nation, speeding in residential neighborhoods is one of the leading causes of citizen complaints. Studies show that resolving the situation using traditional means of enforcement results in only a short-term reduction of speed; violators quickly return to speeding when enforcement ends.

Now, the O’Fallon Police Department is teaming up with the Traffic Department to administer a new anti-speeding program that uses the help of citizen volunteers. Pairs of volunteers will use hand-held radar units to monitor neighborhood streets for speeding. Violations of 15 MPH or greater will be logged, and the information will be turned over to the Traffic Department. The Police Department will contact violators and ask for voluntary compliance with the law. No arrests will be made or tickets issued. The goal of the program is education and compliance.
