        306.9  DIAGONAL ROADS -- RESTORING AND IMPROVING
      EXISTING ROADS.
         It is the policy of the state of Iowa that relocation of primary
      highways through cultivated land shall be avoided to the maximum
      extent possible.  When the volume of traffic for which the road is
      designed or other conditions, including designation as part of the
      network of commercial and industrial highways, require relocation,
      diagonal routes shall be avoided if feasible and prudent alternatives
      consistent with efficient movement of traffic exist.
         The improvement of two-lane roads shall utilize the existing
      right-of-way unless alignment or other conditions, including
      designation as part of the network of commercial and industrial
      highways, make changes imperative, and when a two-lane road is
      expanded to a four-lane road, the normal procedure shall be that the
      additional right-of-way be contiguous to the existing right-of-way
      unless relocated for compelling reasons, including the need to
      provide efficient movement of traffic on the network of commercial
      and industrial highways.  This policy does not apply to a highway
      project for which the corridor has been approved by the state
      department of transportation and the corridor has been finalized by
      September 1, 1977.
         It is the policy of the state of Iowa that in constructing primary
      highways designed with four-lane divided roadways, access controls
      shall be limited to the minimum level necessary, as determined by the
      department, to ensure the safe and efficient movement of traffic or
      to comply with federal aid requirements.
         Unless otherwise required by the federal law or regulation, it is
      also the policy of this state that road use tax fund moneys shall be
      used to rehabilitate or reconstruct existing roads, streets, and
      bridges using substantially existing right-of-way.  This paragraph
      does not apply where additional right-of-way is needed for the
      construction or completion of designated interstate or city routes
      and highway bypasses or highways designated as part of the network of
      commercial and industrial highways.
