306C.21  Information centers and rest areas.
  The department may establish or enter into agreements with private persons, firms, or corporations for the establishment of information centers in rest areas on the interstate, freeway primary, and primary highways, subject to the approval of the appropriate authority of the federal government. After January 1, 1997, private persons, firms, or corporations entering into an agreement with the department under this section shall not develop, establish, or own any commercial business located on land adjacent to the rest area which is subject to the agreement.
  An interstate rest area shall be located entirely on the interstate right-of-way, including, but not limited to, all entrance and exit ramps, all rest area buildings including information centers, and all parking facilities. Department money and resources shall not be used for any other type of interstate rest area. Whenever an interstate rest area is reconstructed, the area available for parking shall be equal to or more than the area available for parking prior to the reconstruction.
