Ala. Code § 45-36-180.09
The authority of the county engineer shall be limited to the expenditure of funds, as may be appropriated by the county commission, for the purpose of constructing, maintaining, or repairing public roads, bridges, and ferries and the supervision of the solid waste system of the county. The county commission, however, is authorized from time to time within such period to increase the amount so appropriated, to be expended by the county engineer during the period, and may deposit such to the account of the department of public works, when such authorization does not conflict with Section 11-8-3, and provided further that, if such funds are then available, and are not set aside by the State Department of Transportation or by the present county commission, upon October 1, 1979, it shall be the duty of the county commission to set aside a sufficient portion of the funds for the maintenance of roads, bridges, and ferries and supervision of the garbage system until after the first meeting in October of 1980. All monies designated for roads shall be kept in a separate account.
