Minn. Stat. § 173.06
The commissioner of transportation must adopt and may modify, amend, or repeal rules governing the maintenance of legal nonconforming advertising devices within scenic areas; provided that the commissioner shall not adopt, modify, amend, or repeal any rule that will impair any agreement between the state and the federal government under this chapter. The commissioner of transportation may limit the application of any rule adopted by the commissioner to exclude or include in whole or in part, specified areas within the scenic area based upon use, nature of the surrounding community, or such other factors as may make separate classification or rule necessary or desirable.
Such rules shall be designed to the end that the state may receive any federal participation that may be available in the cost of acquiring the necessary easements for such scenic areas, and to effectuate the general purposes of Laws 1971, chapter 883, and the specific objectives of providing for traffic safety along any interstate or primary highway in the vicinity of scenic areas and of preserving and enhancing the natural scenic beauty or the aesthetic features of the highway and scenic areas adjacent thereto.
