The Legislature recognizes that federal aid for secondary highways was deleted from federal law by the Intermodal Surface Transportation Efficiency Act of 1991 (Public Law 102-240), and that a period of time is required to account for expenditures of federal funds provided for these purposes under previous federal transportation acts. This chapter shall remain in effect until the director determines that apportionments of all federal aid for secondary highways have been expended. Upon making that determination, the director shall submit a notice to that effect to the Secretary of State, and this chapter shall be repealed on January 1 following the receipt of that notice by the Secretary of State.
