Whenever any public money, whether arising from taxation or from bonds heretofore or hereafter issued, is to be expended in the construction, reconstruction or other improvement of any road, or bridge or culvert, the county commission, township board or road district commissioners, as the case may be, shall have full power and authority to construct, reconstruct or otherwise improve any road, and to construct any bridge or culvert in such county or other political subdivision of the state, and to that end may contract for such work, or may purchase machinery, employ operators and purchase needed materials and employ necessary help and do such work by day labor.

2. The county commission, the township board or road district commissioners may accept donations of labor or materials from interested parties either on road improvements or bridge constructions and said authority may employ labor or contractors to complete said improvements.

3. Before beginning the construction or improvement of any road, bridge or culvert by day labor or by contract, the plans, specifications, estimates of drainage, maps, profiles, estimates of cost and the specific location of such road, bridge or culvert shall be filed in the office of the county clerk, township clerk, or commissioner of road district, as the case may be, and before becoming effective shall be approved by said county, township or road district authorities.

4. On completion of the work a detailed statement of the cost shall be filed as in section 229.050 provided, and shall be recorded in the book wherein are recorded contractors' bids; when any payrolls or construction accounts are certified to as correct by the engineer in charge of the work, the bills for the same shall be passed upon by the county commission, township board or district commissioner, and if found correct, shall be paid; provided, that all such work shall be done under the supervision and direction of the county highway engineer, or some other competent engineer employed by the county commission or other proper authority, at such compensation as may be agreed upon, payable wholly or in part out of the particular fund to be expended on said construction, reconstruction or other improvement.
