Functional Classification

Montana follows the Functional Classification (FC) system for both state and non-state roads.

To properly determine the type of a Freeway, Major Highway, Minor Highway, or Primary Street, refer to the MDT Functional Classification map and cross reference that against the Waze Functional Classification table.

GIS Resources

Consolidated

A Montana Area Manager has created an ArcGIS map which consolidates data from many of the following resources as layers on one map. There is also a script which will open the map and keep it synced to your current view.

Statewide

By County

Some counties also offer interactive GIS maps. Those we are aware of are found here.

By City


MDT City, County, Urban, and Unincorporated Maps

MDT Incorporated City Maps

MDT County Maps

County maps show roads on a land grid of township,range and section lines. MDT departmental route id's are indicated with a beginning label and ending label, and MDT corridor id's are added to some routes where possible. These maps do not imply roadway ownership or maintenance responsibility. Cultural features adjacent to roads are displayed by symbols. The maps also indicate managed areas by owner, lakes, reservoirs, streams, canals/ditches, and, railroads.

  • City areas are blocked out on these PDF maps but they are available in the Urban maps, City Systems maps and Unincorporated Town Maps.

MDT Urban Maps

Highway Systems include:

  • the National Highway System (NHS) - includes the Interstate and other principal arterials
  • the Primary Highway System
  • the Secondary Highway System
  • the Primary Streets

The six functional classifications for urbanized and urban areas include:

  • Principal Arterials

MDT Unincorporated Town Maps

Unincorporated town maps show public roads on a land grid of township, range and section lines. These maps do not imply roadway ownership or maintenance responsibility. Cultural features adjacent to roads are displayed by symbols. The maps also indicate managed areas by owner, lakes, reservoirs, streams, canals/ditches, and, railroads
