(a) Whenever in the opinion of the Department a public road crossing of a railroad at grade should be abandoned, the Department may close and vacate the public road or such part thereof as may be necessary to prevent the use of the grade crossing. If, in the opinion of the Department, the convenience of the traveling public requires it, the Department shall relocate the public road or the part thereof thus vacated and shall connect the public road with some other public road which crosses the railroad. The Department may acquire any land, building, franchise, easement or other property necessary for the relocation of the road by purchase thereof or by condemnation proceedings as provided in Chapter 61 of Title 10. The character of the construction of the relocated public road shall be at the discretion of the Department and need not conform to the usual standards of the Department.
(b) Whenever any public road is vacated, who shall enclose the same or any part thereof and what portion of the costs such persons ought to pay respectively shall be determined as provided in Chapter 13 of this title.
