The portion of the revenue of the tax levied by section 5735.05 of the Revised Code that is described under divisions (A)(3) and (B) of that section shall be partially allocated to provide funding for townships. Each township shall receive the greater of the following two calculations:
No part of the funds designated for road and highway purposes shall be used for any purpose except to pay in whole or part the contract price of any such work done by contract, or to pay the cost of labor in planning, constructing, widening, and reconstructing such roads and highways, and the cost of materials forming a part of the improvement; provided that the funds may be used for the purchase of road machinery and equipment, the planning, construction, purchase, and maintenance of suitable buildings for housing road machinery and equipment, and the payment of principal, interest, and charges on bonds and other obligations issued pursuant to Chapter 133. or 505. of the Revised Code for the purpose of purchasing road machinery and equipment or planning, constructing, purchasing, and maintaining suitable buildings for housing road machinery and equipment; and provided that all such improvement of roads shall be under supervision and direction of the county engineer as provided in section 5575.07 of the Revised Code. No obligation against the funds shall be incurred unless plans and specifications for the improvement, approved by the county engineer, are on file in the office of the township fiscal officer, and all contracts for material and for work done by contract shall be approved by the county engineer before being signed by the board of township trustees. The board of township trustees of any township may pass a resolution permitting the board of county commissioners to expend the township's share of the funds, or any portion of it, for the improvement of the roads within the township as may be designated in the resolution.
All investment earnings of the highway operating fund shall be credited to the fund.
