Any change in location must be spread upon the minutes of the Mississippi Transportation Commission and be approved by an affirmative vote of all three (3) commissioners. The Mississippi Transportation Commission may alter construction standards of an approved route by an affirmative vote of all three (3) commissioners; provided that such change is in conformity with items (a), (b), (c), (d), (e) and (f) of this subsection.
