In addition to all other powers given and assigned to the commissioner in this chapter, the commissioner may acquire, either temporarily or permanently, in the name of the state road commission all real or personal property, public or private, or any interests or rights therein, including any easement, riparian right, or right of access, deemed by the commissioner to be necessary for present or presently foreseeable future state road purposes by gift, lease, grant, bequest, devise, agreement, purchase, exchange, right of eminent domain, or other lawful means. Such real property may be acquired in fee simple or in any lesser estate or interest therein, except in the case of a public road the right-of-way only shall be acquired. Acquisition of such personal property shall be subject to the provisions of sections thirteen and fifteen of this article. The acquisition of any and all such real and personal property is hereby declared to be a cost of highway construction. Nothing in this section shall be deemed to restrict or relinquish any right the state or any agency thereof now or hereafter possesses or may exercise by virtue of the police power or other lawful authority.

(a) Constructing, establishing, laying out, widening, enlarging, extending, straightening, reconstructing, relocating, grading, altering, improving, and maintaining state roads;

(i) Development and maintenance of parking places, auto camps, camp sites, roadside parks, historic roadside markers and sites, forest or timbered areas or other places of attraction and scenic value which are adjacent to or near any state road and which in the judgment of the commissioner are necessary for the convenience of the public and will contribute to the general welfare and pleasure of the motoring public or road users;

(o) Acquisition of real property, not needed as such for a state road, for the purpose of moving and relocating thereon a building or other structure or appurtenance which is situated on a lot or tract of land all or a portion of which is needed for a state road and which, after relocation, will be suitable for the purpose for which it was used prior to its being relocated: Provided, however, That such additional real property may be acquired by the commissioner by condemnation only if the following conditions are satisfied: (1) The building or other structure or appurtenance is of substantial value, (2) the real property on which it is to be relocated is not substantially improved and is adjacent to or near the location from which it is to be removed, (3) the owner of the real property needed for the state road has entered into a written agreement with the commission to accept in exchange the additional property with the relocated building or structure or appurtenance thereon, (4) substantial savings in expenditure of state road funds will result from condemning the additional property and relocating the building or structure or appurtenance rather than condemning the lot or tract, or the portion thereof, on which the building or other structure or appurtenance may be located, and (5) the real property with the relocated building or structure or appurtenance thereon will be relatively equal in value to the real property needed for the state road.
