Description: This layer consists of Minnesota Department of Transportation's roadway Functional Classifications, as of December 31, 2023. Updated annually, Functional Classification defines the type of service a route or route segment provides. Each route is classified as either: Principal Arterial (Interstate), Principal Arterial (Other Freeway or Expressway), Principal Arterial (Other), Minor Arterial, Major Collector, Minor Collector, or Local. Also included in this dataset are Route IDs, which are unique IDs assigned by MnDOT's Linear Referencing System for each route within a jurisdiction.
