Sec. 15. (a) In any resolution or trust agreement providing for the issuance of revenue bonds pursuant to section 14 of this chapter, the authority may further covenant and agree that moneys deposited in the Indiana interstate bridge fund from revenues of other bridges as reimbursement to such fund will be used to pay the interest on or principal of such bonds due but unpaid if, at any time, the available revenues of the bridge to be constructed or acquired by purchase from the proceeds of such bonds are not sufficient to pay such interest or principal. Any coupons or bonds so paid from moneys in the Indiana interstate bridge fund shall be held uncancelled by the authority as a part of the Indiana interstate bridge fund until the amount represented by such coupons or bonds is reimbursed to the fund as provided in this section. Any revenues of the bridge constructed or acquired by purchase from the bond issue of which the coupons or bonds held in the Indiana interstate bridge fund are a part and which are received thereafter and are not required to pay the cost of maintaining, repairing, and operating such bridge or to pay principal and interest on other bonds of the issue or to maintain the sinking fund or any other reserves, if any, at the level prescribed in the resolution or trust agreement, shall be applied to reimbursement of the Indiana interstate bridge fund in an amount not exceeding the amount represented by such coupons or bonds. Such revenues shall be applied first to coupons and then to bonds and in each case in their numerical order. Whenever the Indiana interstate bridge fund is reimbursed for the amount of any coupon or bond, such coupon or bond shall be cancelled. A coupon or bond shall not bear interest for the period held as part of the Indiana interstate bridge fund and the fund shall be deemed to be fully reimbursed for any coupon or bond when it receives the face amount of any such coupon or bond.

     (b) If the authority agrees and covenants as provided in this section in connection with more than one (1) issue of revenue bonds, a bond issue bearing an earlier date than another bond issue shall have priority as to payment of principal and interest from the Indiana interstate bridge fund. However, so long as the revenues of any bridge are sufficient to pay principal and interest due and owing on the bonds issued for the purpose of constructing or acquiring such bridge, moneys in the Indiana interstate bridge fund may be used as provided in this section to pay the principal and interest on any other bond issue even though such bond issue bears a subsequent date.

     (c) Nothing contained in this section shall be construed as permitting the use of money in said fund derived from state appropriations for these purposes, and the books of account of the authority that disclose the amounts in said fund from various sources shall be open for inspection by the general public. Any expenditures from the Indiana interstate bridge fund pursuant to section 18 of this chapter shall first be made from money in said fund derived from sources other than reimbursement from revenues of other bridges.
