        306A.6  NEW AND EXISTING FACILITIES -- GRADE-CROSSING
      ELIMINATIONS.
         Cities and highway authorities having jurisdiction and control
      over the highways of the state, as provided by chapter 306 may
      designate and establish an existing street or highway as included
      within a controlled-access facility.  The state or any of its
      subdivisions shall have authority to provide for the elimination of
      intersections at grade of controlled-access facilities with existing
      state and county roads, and city or village streets, by grade
      separation or service road, or by closing off such roads and streets
      at the right of way boundary line of such controlled-access facility,
      the provisions of sections 306.11 to 306.17 shall apply and govern
      the procedure for the closing of such road or street and the method
      of ascertaining damages sustained by any person as a consequence of
      such closing, provided, however, that the highway authority desiring
      the closing of such road or street shall conduct the hearing and
      carry out the procedure therefor and pay any damages, including any
      allowed on appeal, as a consequence thereof, any law to the contrary
      notwithstanding, and after the establishment of any controlled-access
      facility, no highway or street which is not part of said facility
      shall intersect the same at grade.  No city or village street, county
      or state highway, or other public way shall be opened into or
      connected with any such controlled-access facility without the
      consent and previous approval of the highway authority in the state,
      county, city or village having jurisdiction over such
      controlled-access facility.  Such consent and approval shall be given
      only if the public interest shall be served thereby.
