The Attorney General, whenever he deems it advantageous to the Government and upon such terms and conditions as he deems advisable, is authorized on behalf of the United States to grant to any State, or any agency or political subdivision thereof, easements in and rights-of-way over lands belonging to the United States which are under his supervision and control. Such grant may include the use of such easements or rights-of-way by public utilities to the extent authorized and under the conditions imposed by the laws of such State relating to use of public highways. Such partial, concurrent, or exclusive jurisdiction over the areas covered by such easements or rights-of-way, as the Attorney General deems necessary or desirable, is ceded to such State. The Attorney General is authorized to accept or secure on behalf of the United States from the State in which is situated any land conveyed in exchange for any such easement or right-of-way, such jurisdiction as he may deem necessary or desirable over the land so acquired.
