        306A.4  DESIGN OF CONTROLLED-ACCESS FACILITY.
         Cities and highway authorities having jurisdiction and control
      over the highways of the state, as provided by chapter 306, are
      authorized to so design any controlled-access facility and to so
      regulate, restrict, or prohibit access as to best serve the traffic
      for which such facility is intended.  In this connection such cities
      and highway authorities are authorized to divide and separate any
      controlled-access facility into separate roadways by the construction
      of raised curbings, central dividing sections, or other physical
      separations, or by designating such separate roadways by signs,
      markers, stripes, and other devices.  No person shall have any right
      of ingress or egress to, from, or across controlled-access facilities
      to or from abutting lands, except at such designated points at which
      access may be permitted, upon such terms and conditions as may be
      specified from time to time.
