Category assignments and management guidelines
Working with city and county representatives, MnDOT has developed guidelines for managing access to the state highway system. Every highway segment has been assigned one of two categories:
- Primary access category based on the roadway's functional and strategic importance within the statewide network
- Subcategory based on the existing and planned land use for the surrounding area
Within each primary access category are Urban Core, Urbanizing, and Rural subcategories, which are based on the existing and planned land use of the surrounding area. The recommended spacing and allowance for public street intersections and private access varies with the highway's primary category and subcategory. MnDOT applies the access management guidelines when reviewing plats, subdivisions, environmental documents and development plans and when conducting access permit review.
