Sts. & Hy. Code, § 188.4

(a) Maintenance expenditures on all toll facilities owned by the state shall, for accounting purposes, be classified as Category A or Category B expenditures. Notwithstanding any other provision of law, the cost of maintenance of toll facilities in the geographic jurisdiction of the Metropolitan Transportation Commission shall be paid in accordance with the following:

(1) Category A maintenance shall be paid from the State Highway Account and shall include all normal highway maintenance which would be performed by the state according to state procedures as if the facility was a toll-free state facility.

(2) Category B maintenance shall be paid from toll revenues and shall include all maintenance and reconstruction work of those facilities such as toll facility administration buildings and toll booths which are constructed primarily for the purpose of collecting tolls.

(b) In no event shall the Category A maintenance expenditures for the toll bridges in the geographic jurisdiction of the Metropolitan Transportation Commission be funded at a lower percentage than was established in accordance with procedures for funding Category A maintenance of the toll bridges during the 1986–87 fiscal year.

(c) Notwithstanding subdivisions (a) and (b), for each toll bridge specified in Section 30910, maintenance expenditures shall be funded from toll revenues. However, for a toll bridge that is part of the program specified in Section 188.5, maintenance expenditures shall be funded from toll revenues commencing with the completion of the seismic retrofit or replacement work on that bridge as described in Section 188.5. For the purposes of this subdivision, until the obligations of the California Infrastructure and Economic Development Bank secured by the seismic retrofit surcharge imposed pursuant to subdivision (a) of Section 31010 are no longer outstanding, as that term is defined in the constituent instruments defining the rights of the holders of those obligations, the term “toll revenues” shall not include the seismic retrofit surcharge imposed pursuant to subdivision (a) of Section 31010, and the seismic retrofit surcharge imposed pursuant to subdivision (a) of Section 31010 shall remain pledged to the payment of obligations incurred by the California Infrastructure and Economic Development Bank under Chapter 4.6 (commencing with Section 31070). Maintenance expenses that are required to be funded with toll revenues and that would otherwise constitute Category A maintenance expenditures shall be funded from toll revenues remaining after provision is made for payment of all obligations secured by the lien on toll revenues created by subdivision (b) of Section 30960.
