1. Who is responsible for the various roads in the county?: The County Highway Department is responsible for maintenance of public roads in the unincorporated areas of St. Charles that are not under the control of the Missouri Department of Transportation (MoDOT) or the local municipalities. MoDOT controls any lettered or numbered route (Route A, Route DD, Route F, Hwy. 79, Hwy. 94, etc.). The local cities control any roadways within their municipal boundaries.

2. When it snows, when can I expect a snow plow to come to my street?: The County has a set procedure for responding to winter storms. In an effort to provide the most benefit for the most motorists, the first priority is to clear the arterial (main) roads first. Once those roadways are properly cleared, the snow removal trucks will move to the main subdivision streets. Attention is then turned to the secondary subdivision streets, and finally the cul de sacs. The actual time it takes to get to a particular street depends on many factors, including the severity of the storm, the type of precipitation, the temperatures, etc. If the conditions warrant, County Highway Department crews will work around the clock, using 12 hour shifts.

3. How do I find out when a project will be complete?: For information about the status of a specific project, please call the Highway Department at 636-949-7305.

4. How do I request a new stop sign to be installed in my neighborhood?: Any request for a new stop sign, no parking area, or other traffic regulation must be submitted to the County Highway Department, along with a petition that includes the signatures of 15 residents living in the area that support the requested regulation. Once that petition is received, it is held on file in the Highway Department office until public hearings before the County Council can be scheduled (usually 2-3 times a year, depending on the number of requests received). Following the public hearings, each request is reviewed by the Highway Department, and a recommendation is made to the County Council. The Council then decides on whether the requested regulation should be approved.
