2. Bikeway routes shall be clearly marked with appropriate signs to guide cyclists and to alert motorists. Such signs shall be placed at intervals and designed in such form as prescribed by the department of natural resources in consultation with the state transportation commission.

3. The department of natural resources is hereby authorized to cooperate with county conservation boards, boards of supervisors, city councils, or any private organizations interested in the establishment of bikeways, and may consult with such groups in the planning of appropriate bikeway routes and related activities.
