Sec. 6. When so executed, such bonds shall be sold as now provided by law for the sale of other county bonds, except that, in addition to any other notice required by law, such bonds shall be advertised in a public newspaper of general circulation published at the city of Indianapolis, Indiana;  and the proceeds derived from the sale of such bonds shall be forthwith paid over by the county treasurer of such county to the treasurer of state of the state of Indiana, and shall become a part of the state highway funds of said state, to be used in the construction of such bridge and for no other purpose:  Provided, That if the proceeds derived from the sale of such bonds shall amount to more than one-fourth of the actual cost of the construction of such bridge, the excess of such proceeds over and above one-fourth of the actual cost of the construction of such bridge shall, at the completion of such bridge, be repaid by the treasurer of state of the state of Indiana to such county and shall be used by such county in the payment of such bonds and the interest thereon and for no other purpose:  Provided, further, That if, for any cause whatsoever, all or any part of said proceeds derived from the sale of any such bonds of such county shall not be actually used in the construction of such bridge, all of said proceeds not so used shall be repaid to such county and shall be used by it in the payment of such bonds and the interest thereon and for no other purpose;  and if, at any time, the completion of any such bridge shall be abandoned, or shall be permanently or perpetually enjoined by decree of any court, from which no appeal is taken within the time of appeal allowed by law, and thereafter prosecuted with due diligence, or if the completion of such bridge be rendered impracticable by natural causes or otherwise, then in any such event all funds derived from the sale of county bonds hereunder and placed with the treasurer of state, as herein provided, to be used as a part of the state highway funds of the state in the construction of such bridge, and not so used, shall thereupon, together with any and all depository interest which shall have accrued on such fund while in the possession of the treasurer of state, be returned at once by the treasurer of state to the said county, and shall be used by it in payment of such bonds so issued by it as aforesaid and the interest thereon and for no other purpose.
