for projects on the Federal-aid primary system or extensions of any of the Federal-aid highway systems in urban areas and the retirement of the principal and interest of such bonds the proceeds of which were used for projects on the Interstate System at their maturities, to the extent that the proceeds of such bonds have been actually expended in the construction of one or more of such projects. Such claim for payment may be made only when all of the provisions of this title have been complied with to the same extent and with the same effect as though payment were to be made to the State under section 121 of this title, instead of this section, and the Federal share payable shall not exceed the pro rata basis of payment authorized in section 120 of this title. This section shall not be construed as a commitment or obligation on the part of the United States to provide for the payment of the principal or interest of any such bonds. The payment of interest on such bonds and incidental costs in connection with the sale of such bonds shall not be included in the estimated cost of completing the Interstate System. 113

Sec. 123. Relocation of utility facilities.

(a) When a State shall pay for the cost of relocation of utility facilities necessitated by the construction of a project on the Federal-aid primary or secondary systems or on the Interstate System, including extensions thereof within urban areas, Federal funds may be used to reimburse the State for such cost in the same proportion as Federal funds are expended on the project. Federal funds shall not be used to reimburse the State under this section when the payment to the utility violates the law of the State or violates a legal contract between the utility and the State. Such reimbursement shall be made only after evidence satisfactory to the Secretary shall have been presented to him substantiating the fact that the State has paid such cost from its own funds with respect to Federal-aid highway projects for which Federal funds are obligated subsequent to April 16, 1958, for work, including relocation of utility facilities.

(b) The term "utility", for the purposes of this section, shall include publicly, privately, and cooperatively owned utilities.

(c) The term "cost of relocation", for the purposes of this section, shall include the entire amount paid by such utility properly attributable to such relocation after deducting therefrom any increase in the value of the new facility and any salvage vaiue derived from the old facility. Sec. 124. Advance to States.

(a) If the Secretary shall determine that it is necessary for the expeditious completion of projects on any of the Federal-aid systems, including the Interstate System, he may advance to any State out of any

existing appropriations the Federal share of the cost of construction thereof to enable the State highway department to make prompt payments for acquisition of rights-of-way, and for the construction as it progresses. The sums so advanced shall be deposited in a special revolving trust fund, by the State official authorized under the laws of the State to receive Federal-aid highway funds, to be disbursed solely upon vouchers approved by the State highway department for rightsof-way which have been or are being acquired, and for construction which has been actually performed and approved by the Secretary pursuant to this chapter. Upon determination by the Secretary that any part of the funds advanced to any State under the provisions of this section are no longer required, the amount of the advance, which is determined to be in excess of current requirements of the State, shall be repaid upon his demand, and such repayments shall be returned to the credit of the appropriation from which the funds were advanced. Any sum advanced and not repaid on demand shall be deducted from sums due the State for the Federal pro rata share of the cost of construction of Federal-aid projects. 113b

(b) Notwithstanding subsection (a) of this section, if the Secretary of Transportation determines that any toll bridge, toll tunnel, or approach thereto, which meets the requirements of section 129 of this title is necessary to complete an essential gap in the Interstate System then, upon request of the State highway department, the Secretary shall, at any time during construction of such bridge, tunnel, or approach and for one year after it is opened to traffic, and subject to the conditions and limitations of such section 129, advance to such State 100 per centum of the cost of construction of such bridge, tunnel, or approach. So much of the amount so advanced that exceeds the Federal share of such construction cost shall be repaid to the United States as follows: (1) 50 per centum within one year of the date such bridge, tunnel, or approach is opened to traffic,

(2) 25 per centum within two years of such date of opening, and (3) 25 per centum within three years of such date of opening. Any advance made to a State under this subsection shall be from the funds apportioned to said State for the Interstate System. So much of any advance made to a State under this subsection required to be repaid shall be repaid with interest at a rate determined by the Secretary. If a State receives any advance under this subsection with respect to any toll bridge, tunnel, or approach thereto, then the provisions of section 103(e)(4) of this title shall not apply to such bridge, tunnel, or approach. 113c

In no event shall funds be used pursuant to this section for the repair or reconstruction of bridges which have been permanently closed to all vehicular traffic by the State or responsible local official because of imminent danger of collapse due to structural deficiencies or physical deterioration. Subject to the following limitations, there is hereby authorized to be appropriated from the Highway Trust Fund such sums as may be necessary to establish the fund authorized by this section and to replenish it on an annual basis: (1) Not more than $50,000,000 is authorized to be expended in any fiscal year ending before July 1, 1972 and not more than $100,000,000 is authorized to be expended in any one fiscal year commencing after June 30, 1972 and ending before June 1, 1976, to carry out the provisions of this section and an additional amount not to exceed $100,000,000 is further authorized to be expended in the fiscal year ending June 30, 1973, to carry out the provisions of this section, and not more than $25,000,000 for the three-month period beginning July 1, 1976, and ending September 30, 1976, is authorized to be expended to carry out the provisions of this section, and not more than $100,000,000 is authorized to be expended in any one fiscal year commencing after September 30, 1976, and not more than $100,000,000 is authorized to be expended in any one fiscal year commencing after September 30, 1980, to carry out the provisions of this section, except that, if in any fiscal year the total of all expenditures under this section is less than the amount authorized to be expended in such fiscal year, the unexpended balance of such amount shall remain available for expenditure during the next two succeeding fiscal years in addition to amounts otherwise available to carry out this section in such years, and (2) prior to the fiscal year ending September 30, 1978, 60 per centum of the expenditures under this section for any fiscal year are authorized to be appropriated from the Highway Trust Fund and the remaining 40 per centum of such expenditures are authorized to be appropriated only from any moneys in the Treasury not otherwise appropriated, and for any fiscal year thereafter, 100 per centum of such expenditures are authorized to be appropriated out of the Highway Trust Fund. For the purposes of this section the period beginning July 1, 1976, and ending September 30, 1976, shall be deemed to be a part of the fiscal year ending September 30, 1977.
