The sums herein authorized for each fiscal year shall be available for expenditure as follows: (A) 45 per centum for projects on the Federal-aid primary highway system. (B) 30 per centum for projects on the Federal-aid secondary highway system. (C) 25 per centum for projects on extensions of these systems within urban areas. (2) Apportionments.—The sums authorized by this section shall be apportioned among the several States in the manner now provided by law and in accordance with the formulas set forth in section 4 of the Federal-Aid Highway Act of 1944, approved December 20, 1944 (58 Stat. 838): Provided, That the additional amount herein authorized for the fiscal year ending June 30, 1957, shall be apportioned immediately upon enactment of this Act. (b) Availability for Expenditure.—Any sums apportioned to any State under this section shall be available for expenditure in that State for two years after the close of the fiscal year for which such sums are authorized, and any amounts so apportioned remaining unexpended at the end of such period shall lapse: Provided, That such funds shall be deemed to have been expended if a sum equal to the total of the sums herein and heretofore apportioned to the State is covered by formal agreements with the Secretary of Commerce for construction, reconstruction, or improvement of specific projects as provided in this title and prior Acts: Provided further, That in the case of those sums heretofore, herein, or hereafter apportioned to any State for projects on the Federal-aid secondary highway system the Secretary of Commerce may, upon the request of any State, discharge his responsibility relative to the plans, specifications, estimates, surveys, contract awards, design, inspection, and construction of such secondary road projects by his receiving and approving a certified statement by the State highway department setting forth that the plans, design, and construction for such projects are in accord with the standards and procedures of such State applicable 70 Stat. 375 to projects in this category approved by him: Provided further, That such approval shall not be given unless such standards and procedures are in accordance with the objectives set forth in section 1 (b) of the Federal-Aid Highway Act of 1950: And provided further, That nothing contained in the foregoing provisos shall be construed to relieve any State of its obligation now provided by law relative to maintenance, nor to relieve the Secretary of Commerce of his obligation with respect to the selection of the secondary system or the location of projects thereon, to make a final inspection after construction of each project, and to require an adequate showing of the estimated and actual cost of construction of each project. Any Federal-aid primary, secondary, or urban funds released by the payment of the final voucher or by modification of the formal project agreement shall be credited to the same class of funds, primary, secondary, or urban, previously apportioned to the State and be immediately available for expenditure. (c) Transfers of Apportionments.—Not more than 20 per centum of the respective amounts apportioned to a State for any fiscal year from funds made available for expenditure under clause (A), clause (B), or clause (C) of subsection (a) (1) of this section, may be transferred to the apportionment made to such State under any other of such clauses, except that no such apportionment may be increased by more than 20 per centum by reason of transfers to it under this subsection: Provided, That such transfer is requested by the State highway department and is approved by the Governor of such State and the Secretary of Commerce as being in the public interest: Provided further, That the transfers hereinabove permitted for funds authorized to be appropriated for the fiscal years ending June 30, 1958, and June 30, 1959, shall likewise be permitted on the same basis for funds which may be hereafter authorized to be appropriated for any subsequent fiscal year: And provided further, That nothing herein contained shall be deemed to alter or impair the authority contained in the last proviso to paragraph (b) of section 3 of the Federal-Aid Highway Act of 1944.
