Ohio Revised Code Title LV. Roads Highways Bridges § 5555.94

The board of county commissioners shall repair all substantial damage caused to county or township roads by the transportation of materials or equipment over such roads for use in constructing or repairing any road by such board. Such repairs shall be made immediately upon the completion of the work for which such materials and equipment were transported, or as soon thereafter as weather conditions will permit. The work may be done either by contract let in the manner provided by law or by the employment of labor and purchase of materials, as in the ordinary repair of county roads.

The cost of such repair shall be paid, so far as funds are available, from any balance remaining in any special fund created for the construction of the improvement for which such materials and equipment were transported. If there is no balance in such fund, payment shall be made from any fund in the county treasury created by general taxation for county road purposes and against which no contractual obligations exist. Immediately upon the completion of any road work carried forward by the county, an inspection of the county and township roads over which material and equipment for use thereon were transported shall be made by the board, or it may require the county engineer to make such inspection and report to it in writing as to any substantial damage caused to such roads by such use thereof. The board shall then make the repairs and make payment therefor as provided in this section.
