N.D. Cent. Code § 24-01-04
Except for a municipality located within a designated metropolitan planning organization, each municipality of over five thousand population in this state, according to the latest available census, shall develop and adopt a master street plan cooperatively between the director and the municipal officials, which must ensure the proper location and integration of the state highway connections in the total city street plan. In selecting and designating the master street plan, the cooperating officials shall take into account the more important principal streets that connect the residential areas with business areas, and the streets that carry the important rural traffic into and across the city, to ensure a system of streets upon which traffic can be controlled and protected, in such a manner as to provide safe and efficient movement of traffic within a municipality.
