A relocation of a highway that includes added through travel lanes shall be counted as one unit for purposes of determining the length of the relocation and added through travel lanes. Pavement widening for purposes of adding a passing lane is not an added through travel lane. Notwithstanding the exemption under this paragraph, if minor reconstruction causes a highway to lie within a buffer area, as defined in s.
