The issue of bonds must also provide for a sufficient sum to pay for any extras or changes not contemplated in the original plans, specifications, and contract that the executive considers necessary, and that might be omitted by the engineer who drew the plans or specifications.(b) The proceeds shall be kept as a separate and specific fund to pay for the improvement or construction, reconstruction, or improvement of the particular road for which they were issued. The proceeds shall be paid by the treasurer to the contractor, upon warrant of the auditor, as directed by the executive. The contractor shall be paid in accordance with IC 36-1-12. If there is a surplus left from the sale of the bonds after the road is complete, the surplus shall be transferred to a fund for the construction, reconstruction, or improvement of any other highway in the county and shall not be used for any other purpose. All funds shall be kept in the public depositories of the county and the interest added to the fund.(Formerly: Acts 1919, c.112, s.14.)
