Our History

The creation of the county road system dates back to 1893. It was established by a vote of the people in each county in Michigan. A two-thirds vote of the Board of Supervisors placed the issue on the ballot and by 1905, 18 counties had established a system. In 1909, Act 283 required the Board of Supervisors to place the question on the ballot when 10 freeholders (land owners) in every township submitted a petition. Within 15 years, all counties had voted for a county road system.

For more than 100 years, county road agencies have served their communities and are responsible for the public road system, excluding state highways, city, village and private roads.

Examples of such roads are Metropolitan Parkway (Big Beaver Road in Oakland County) and 14 Mile Road. MCDR’s primary source of funding is the Michigan Transportation Fund. This fund is supported by the state fuel tax and vehicle registration fees. MCDR's allocation is based on a formula, which includes factors such as population, miles of certified roads and vehicle registration fees.

In addition to the Michigan Transportation Fund, MCDR receives federal and state grants for specific construction projects and often partners with townships and cities in Macomb County on road projects. MCDR also has a contract with the Michigan Department of Transportation (MDOT) to maintain Macomb County's state trunklines, including patch work and winter maintenance. Macomb County's network of roads and bridges is essential to the success of our community. Macomb County's economic health depends on a system of transportation that serves every aspect of our community's needs. It assures jobs, business activity, education and an opportunity to improve the quality of life for all of our citizens. MCDR is dedicated to success through progress in transportation, providing a safe, convenient and economically beneficial system of transportation for all Macomb County residents, motorists and visitors.​​
