Minn. Stat. § 89.18: ROADS THROUGH STATE FORESTS.

No public highway, other than a state trunk highway, shall be established or laid out through any state forest as the same shall be created and withdrawn from public sale and entry by existing or subsequent act, without the consent of the commissioner, certified in writing to the public authority having power to establish or lay out such highway. In any judicial proceeding affecting the laying out of a highway, the court may either sustain or reverse the action of the commissioner as the court, in its discretion, may deem proper. The limitations and restrictions provided in this section shall not apply to state-owned lands which have not been expressly withdrawn from sale and created and reserved as state forests. No state forest lands or right or easement therein shall be taken by eminent domain for any purpose without the consent of the commissioner, certified in writing to the authority or corporation exercising such power of eminent domain.
