Control Area Definition

Outside urban boundaries, outdoor advertising is controlled to the limit of visibility or readability of the sign. In commercial and industrial areas, conforming signs must be erected within 660 feet from the edge of the right of way.

The Urban boundary definition and maps are available from the Montana Department of Transportation. In Montana, the urban designation is for cities of populations of 5,000 or more. The boundaries are set by agreement among Federal, State, and Local governments.
