Ala. Code § 11-11A-1
Any county in the state of Alabama, in addition to all other powers which it may now have, is hereby authorized and empowered from time to time to authorize, issue and sell, for the purpose of financing the costs of erecting necessary public buildings, bridges or roads in such county, interest-bearing tax-anticipation warrants payable (as to both principal and interest) solely out of the special ad valorem tax authorized by § 215 of the Constitution of Alabama of 1901, as amended, to be levied for the erection of necessary public buildings, bridges or roads, such warrants to be in such denomination or denominations, to have such maturity or maturities [not exceeding 30 years from their date], to bear interest at such rate or rates and payable at such time or times, to be made payable at such place or places (whether within or without the state) and to be sold at such time or times, in such manner (whether publicly or privately) and at such price [not less than 95 percent of their par or face value plus accrued interest] as the county commission of such county shall determine. Warrants may be issued under the provisions of this chapter, in anticipation of the issuance and sale of longer-term warrants to be issued hereunder, to provide for the temporary financing of the costs of erecting necessary public buildings, bridges or roads, in which event so much of the proceeds from the sale of such longer-term warrants as shall be necessary for such purpose shall be used to pay and retire the principal of and the interest accrued on such shorter-term warrants.
