(1) Any road district bonds and any other indebtedness and liabilities of a road district which are outstanding on the date of a county’s implementation of a countywide system of road administration, as described in Section 19-2-3, shall become obligations of the county as a whole. Any sum being held in a road district fund to repay principal and interest on such bonds shall be deposited into a special county fund to be used toward amortization of such bonds. If any covenants in any road district bonds require that the bonded indebtedness be retired by a tax levy only upon the property within the road district for which the bonds were issued, the board of supervisors shall retire such bonded indebtedness by a tax levy only upon the property in the part of the county which was within the road district immediately before the date of the county’s implementation of the countywide system of road administration.

(2) Any real or personal property of a road district shall become the property of the county in which the district was located immediately before the date of the county’s implementation of the countywide system of road administration.

(3) From and after the date on which the board of supervisors receives certification of the results of an election which require that the county operate on a countywide system of road administration, the board of supervisors of the county shall not issue or authorize to be issued any bonds, notes or other obligations for the benefit of a road district unless prior to the date of certification of the election to the board, a declaration of intent to issue such bonds, notes or other obligations has been duly adopted and entered on the minutes of the board of supervisors of the county and the first publication of such declaration of intent has been completed in the manner provided by law.

(4) The term “road district” as used in this section shall also include separate road districts, special road districts and supervisors districts acting as road districts.
