St. Louis County Public Works Department
About Public Works
St. Louis County is responsible for approximately 3,000 miles of county roads which consist of County State Aid Highways (CSAH), County Roads (CR) and Unorganized Township roads (UT). This is equivalent to a round trip from Duluth, MN to Jacksonville, FL. This county road system includes more than 600 bridges (greater than 10 ft) and 45,000 traffic signs. The county road system is split approximately 50/50 between paved surface roads and gravel surface roads.
Our Mission
To provide a safe, well-maintained road and bridge system that will ensure reliable and convenient access to County services, facilities, recreational and natural resource areas, and employment centers; to enhance the quality of life of St. Louis county residents; and to promote the economic development of the area.
