Sign Maintenance & Repair

The Department of Public Works takes great pride in repairing, replacing, and installing missing street signs. Frequently, signs are damaged or destroyed by automobiles, weather conditions, or vandals. We are asking all residents to help us; if you notice that a street sign is missing, faded or incorrect, please use the Report Street or Traffic Sign Damage page to request sign service. To request a stop sign installation, use the Request a Stop Sign Installation form or call Public Works at 406-497-6565.

The destruction or theft of traffic signs is a tremendous safety hazard. Some signs are essential for public safety, especially in rural areas where emergency responders depend on street signs for quick response. If a sign is being vandalized or stolen, please call the Police Department with any information about the crime at:
