RECREATIONAL BIKEWAYS

  308A.1  Department of natural resources and transportation commissions to cooperate.
  The department of natural resources, in consultation with the state transportation commission, is hereby authorized to establish recreational bikeways within this state for the use, enjoyment, and participation of the public in nonmotorized bicycling. The routes established for such bikeways shall be designed to maximize the safety of cyclists and motorists and may utilize secondary roads when the normal flow of motor vehicle traffic will not be hindered, as well as other infrequently traveled roads, streets, parkways, and appropriate thoroughfares. Such bikeways shall be routed, wherever possible, to allow the enjoyment of scenic views and points of historical interest, and may connect state parks and other recreational areas throughout the state.
  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.
  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.
