The secretary, with the approval of the Governor, may designate the future location and width of any proposed highway, and continue to maintain the present highway until such time as the amount of traffic warrants the construction of the new highway designated and until such new highway has been completed and opened to traffic.

Whenever the secretary shall establish the width and lines of any such highway he shall cause a plan thereof to be made, showing the center line of said highway and the established width thereof, and shall attach thereto his acknowledgment. Thereupon such plan, and acknowledgment shall be recorded in the office of the recorder of deeds of the proper county in a separate book kept for such purpose, which shall be furnished to the recorder of deeds by the county commissioners at the expense of the county.

No owner or occupier of lands, buildings, or improvements shall erect any building or make any improvements within the limits of any State highway the width and lines of which have been established and recorded as provided in this section, and if any such erection or improvement shall be made no allowance shall be had therefor by the assessment of damages.

Any damages sustained by the taking of private property under the provisions of this section for the construction of such highway shall be ascertained and paid as provided by Article III of this act.¹
