The allocation and programming of funds within the state system in each fiscal year shall be according to need, as determined by a schedule of priorities assigned to segments of the existing highways which generally delineate the corridors of said state system of express highways and freeways. The secretary of transportation shall determine the length of each such segment in establishing said priorities, and the schedule of priorities shall be updated every four years on the basis of current criteria at that time. Immediately after the effective date of this act, the secretary of transportation shall evaluate the schedule of priorities and, where necessary, reestablish such schedule in accordance with the following standards and criteria: Except where it is specifically provided by law that any of the highways to be constructed within the corridors designated in subsection (a) shall be constructed so as to include multiple lanes in each direction on roadways separated by a median, barrier or other center division, all highways constructed within the state system of modern express highways and freeways after the effective date of this act may be constructed either with multiple lanes in each direction on roadways separated by a median, barrier or other center division or may be constructed with two lanes on a single roadway. Whenever the secretary of transportation deems it necessary and appropriate for the safety of vehicular traffic, such highways shall be designed and constructed to include controlled access, passing lanes, expanded shoulder width, long-sight distances, grade separations at intersections with other roads and highways and railroads. Nothing herein shall be construed as abrogating, limiting or otherwise affecting the construction of any highway for which bids for the construction thereof have been solicited and received prior to the effective date of this act, nor shall the foregoing be construed as precluding the secretary of transportation, whenever the secretary deems it feasible and appropriate, from acquiring right-of-way sufficient to accommodate the eventual construction of multiple-lane divided highways within any corridor designated in subsection (a).
