2. The provisions of sections 306.11 through 306.17 shall apply and govern the procedure for the closing of a road or street and the method of ascertaining damages sustained by any person as a consequence of the 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.

3. 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. A city or village street, county or state highway, or other public way shall not 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 the controlled-access facility. Such consent and approval shall be given only if the public interest shall be served thereby. [C58, 62, 66, 71, 73, 75, 77, 79, 81, §306A.6] 2020 Acts, ch 1063, §133 \n
