County Routes & Listings

The original focus for the Michigan Highways website was primarily on the State Trunkline Highway System as laid out and maintained by the Michigan Department of Transportation, although an early addition was a catalogue of the Intercounty Highways around the state as well. While detailed information on each county's routes and road systems is still (currently) beyond the scope of this website, here you will find an overview of Michigan's various county route systems—current and historical—and complete information on the statewide Intercounty Highway system.
