        306.41  TEMPORARY CLOSING FOR CONSTRUCTION.
         The agency having jurisdiction and control over any highway in the
      state, or the chief engineer of said agency when delegated by such
      agency, may temporarily close sections of a highway by formal
      resolution entered upon the minutes of such agency when reasonably
      necessary because of construction, reconstruction, maintenance or
      natural disaster and shall cause to be erected "road closed" signs
      and partial or total barricades in the roadway at each end of the
      closed highway section and on the closed highway where that highway
      is intersected by other highways if such intersection remains open.
      Any numbered road closed for over forty-eight hours shall have a
      designated detour route. The agency having jurisdiction over a
      section of highway closed in accordance with the provisions of this
      section, or the persons or contractors employed to carry out the
      construction, reconstruction, or maintenance of the closed section of
      highway, shall not be liable for any damages to any vehicle that
      enters the closed section of highway or the contents of such vehicle
      or for any injuries to any person that enters the closed section of
      highway, unless the damages are caused by gross negligence of the
      agency or contractor.
         Nothing herein shall be construed to prohibit or deny any person
      from gaining lawful access to the person's property or residence, nor
      shall it change or limit liability to such persons.
