About: County roads in Minnesota

County roads in Minnesota are roads locally maintained by county highway departments in Minnesota. County roads span a wide variety of road types, varying from A-minor arterials that carry large volumes of traffic to gravel roads. Most county roads in Minnesota are designated with numbers that are unique within each county. Although most counties designate with only numbers, a few in Dodge County use letters instead, and two in Isanti County use a combination of a number and letter.
