    Traffic Department

    The Road Commission Traffic Department is supervised by Adam Merchant, Traffic Engineer, and Ken Webb, Traffic Department Supervisor. One of the primary responsibilities for the Road Commission’s Traffic Department is to oversee the installation and maintenance of all traffic control devices in Macomb County. Devices that fall into this category range from single traffic control signs to major traffic signal corridors. The Traffic Department performs traffic studies covering a wide range of issues from installation of stop signs, speed limits and parking restrictions to the installation of traffic signals. Traffic works closely with the Engineering Department to ensure that new roadways are built with roadway safety in mind using appropriate curvature and lane configurations.

    We are continually striving to make our existing roadway infrastructure safer and more efficient.


    Sign Department

    The Sign Department works under the direction of our Traffic Department installing and maintaining all the traffic control signs, guardrail installation and pavement markings. Twice a year, the Sign Department paints all of the roads maintained by the Road Commissions. Currently, the Sign Departmnet maintains approximately 60,000 traffic control signs. When critical signs (such as stop signs)are knocked down, the Sign Department’s emergency crews are dispatched to re-install the sign immediately. To report a down or damaged sign, contact (586) 463-8671, 24-hours a day.


    Signal Department

    The Signal Department is also under the direction of the Traffic Department and maintains all of the approximately 1,000 electrical traffic control devices in the county. We currently maintain all of the traffic in Macomb County, including all of those that are located on City and Michigan Department of Transportation roads. To report problems with a traffic signal contact (586) 463-8671, 24-hours a day. The Signal Department routinely changes all of the light bulbs in every traffic signal once a year to prevent bulbs from burning out unexpectedly. We also perform routine maintenance and operation checks at each intersection to ensure that all of the equipment is operating properly.

    Adopt-A-County-Road

    The Adopt-A-County-Road program is designed to help keep county roadsides clean and attractive. This is a great opportunity for all types of organizations who want to become involved in the community. There is no cost to participate in this program. Participants of this program are required to clean the roadsides twice a year (in early spring and late fall). All new participants in the program are required to view a safety video prior to actually participating in any clean up activities. The Road Commission provides trash bags and safety vests to all organizations and participants. For more information, contact Sharon at (586) 463-8671 extension 1104 or click here for our brochure.
