N.D. Cent. Code § 24-16-04
Junkyards lawfully in existence prior to December 3, 1965, which are or may be screened by natural objects, plantings, fences, or other appropriate means so as not to be visible from the main traveled way of the state highway system must be allowed to remain within one thousand feet [304.8 meters] of the nearest edge of the right of way of any state highway; provided, however, that the owners of the junkyards which are not effectively screened shall take all the steps ordered by the commissioner to effectively screen them. When ordered by the director to screen junkyards lawfully in existence prior to December 3, 1965, the owners must be fully reimbursed for the costs expended pursuant to the director's order and design. Should the director determine that the effective screening of any junkyard could best be done by state forces or by an independent contractor, the director may use state forces or may let a contract for the screening in the same manner that contracts are let pursuant to this title for construction and reconstruction of the state highway system and the director has the right to enter upon private property for the purpose of screening said junkyards without liability on the director's part.
