Sec. 52d.  COUNTY OR ROAD DISTRICT TAX FOR ROAD AND BRIDGE PURPOSES IN HARRIS COUNTY.  (a)  Upon the vote of a majority of the qualified voters so authorizing, a county or road district may collect an annual tax for a period not exceeding five (5) years to create a fund for constructing lasting and permanent roads and bridges or both.  No contract involving the expenditure of any of such fund shall be valid unless, when it is made, money shall be on hand in such fund.
(b)  At such election, the Commissioners' Court shall submit for adoption a road plan and designate the amount of special tax to be levied; the number of years said tax is to be levied; the location, description, and character of the roads and bridges; and the estimated cost thereof.  The funds raised by such taxes shall not be used for purposes other than those specified in the plan submitted to the voters.  Elections may be held from time to time to extend or discontinue said plan or to increase or diminish said tax.  The Legislature shall enact laws prescribing the procedure hereunder.
(c)  The provisions of this section shall apply only to Harris County and road districts therein.
