(a) In any case in which the Secretary is requested by a State to acquire lands or interests in lands (including within the term "interests in lands", the control of access thereto from adjoining lands) required by such State for right-of-way or other purposes in connection with the prosecution of any project for the construction, reconstruction, or improvement of any section of the Interstate System, the Secretary is authorized, in the name of the United States and prior to the approval of title by the Attorney General, to acquire, enter upon, and take possession of such lands or interests in lands by purchase, donation, condemnation, or otherwise in accordance with the laws of the United States (including sections 3114 to 3116 and 3118 of title 40), if—

(1) the Secretary has determined either that the State is unable to acquire necessary lands or interests in lands, or is unable to acquire such lands or interests in lands with sufficient promptness; and

(2) the State has agreed with the Secretary to pay, at such time as may be specified by the Secretary an amount equal to 10 per centum of the costs incurred by the Secretary, in acquiring such lands or interests in lands, or such lesser percentage which represents the State's pro rata share of project costs as determined in accordance with subsection (c) ¹ of section 120 of this title.

The authority granted by this section shall also apply to lands and interests in lands received as grants of land from the United States and owned or held by railroads or other corporations.

(b) The costs incurred by the Secretary in acquiring any such lands or interests in lands may include the cost of examination and abstract of title, certificate of title, advertising, and any fees incidental to such acquisition. All costs incurred by the Secretary in connection with the acquisition of any such lands or interests in lands shall be paid from the funds for construction, reconstruction, or improvement of the Interstate System apportioned to the State upon the request of which such lands or interests in lands are acquired, and any sums paid to the Secretary by such State as its share of the costs of acquisition of such lands or interests in lands shall be deposited in the Treasury to the credit of the appropriation for Federal-aid highways and shall be credited to the amount apportioned to such State as its apportionment of funds for construction, reconstruction, or improvement of the Interstate System, or shall be deducted from other moneys due the State for reimbursement from funds authorized to be appropriated under section 108(b) of the Federal-Aid Highway Act of 1956.

(c) The Secretary is further authorized and directed by proper deed, executed in the name of the United States, to convey any such lands or interests in lands acquired in any State under the provisions of this section, except the outside five feet of any such right-of-way in any State which does not provide control of access, to the State transportation department of such State or such political subdivision thereof as its laws may provide, upon such terms and conditions as to such lands or interests in lands as may be agreed upon by the Secretary and the State transportation department or political subdivisions to which the conveyance is to be made. Whenever the State makes provision for control of access satisfactory to the Secretary, the outside five feet then shall be conveyed to the State by the Secretary, as herein provided.

(d) Whenever rights-of-way, including control of access, on the Interstate System are required over lands or interests in lands owned by the United States, the Secretary may make such arrangements with the agency having jurisdiction over such lands as may be necessary to give the State or other person constructing the projects on such lands adequate rights-of-way and control of access thereto from adjoining lands, and any such agency is directed to cooperate with the Secretary in this connection.
