County Highways
The Lake County Division of Transportation is responsible for planning, designing, constructing and maintaining certain Lake County highways. Roads under the jurisdiction of Lake County are identified by the 5-sided blue and gold route markers pictured at left, a system of more than 300 centerline miles of arterial and collector roads and more than 62 miles of bike facilities. A county highway must meet criteria established by state law, have been designated a county highway by the county board and approved by the state.
