Ohio Rev. Code § 4582.57
When a port authority finds it necessary to change the location of any portion of any public road, state highway, railroad, or public utility facility in connection with the construction of a port authority facility, it shall cause it to be reconstructed at such location as the division of government having jurisdiction over such road, highway, railroad, or public utility facility finds most favorable. Such construction shall be of substantially the same type and in as good condition as the original road, highway, railroad, or public utility facility. The cost of such reconstruction, relocation, or removal and any damage incurred in changing the location of any such road, highway, railroad, or public utility facility shall be paid by the port authority as a part of the cost of the port authority facility.
When the port authority finds it necessary that any public highway or portion of a public highway be vacated by reason of the acquisition or construction of a port authority facility, the port authority may request the director of transportation, in writing, to vacate such highway or portion in accordance with section 5511.07 of the Revised Code if the highway or portion to be vacated is on the state highway system, or, if the highway or portion to be vacated is under the jurisdiction of the county commissioners, the port authority shall request the director, in writing, to petition the board of county commissioners, in the manner provided in section 5553.041 of the Revised Code, to vacate such highway or portion. The port authority shall pay to the director or to the county, as a part of the cost of such port authority facility, any amounts required to be deposited with any court in connection with proceedings for the determination of compensation and damages and all amounts of compensation and damages finally determined to be payable as a result of such vacation.
The port authority may adopt reasonable rules for the installation, construction, maintenance, repair, renewal, relocation, and removal of railroad or public utility facilities in, on, over, or under any port authority facility. Whenever the port authority determines that it is necessary that any such facilities installed or constructed in, on, over, or under property of the port authority pursuant to such rules be relocated, the public utility owning or operating such facilities shall relocate or remove them in accordance with the order of the port authority. The cost and expenses of such relocation or removal, including the cost of installing such facilities in a new location, the cost of any lands, or any rights or interests in lands, and any other rights, acquired to accomplish such relocation or removal, shall be paid by the port authority as a part of the cost of the port authority facility. In case of any such relocation or removal of such facilities, the railroad or public utility owning or operating them, its successors, or assigns may maintain and operate such facilities, with the necessary appurtenances, in the new location in, on, over, or under the property of the port authority for as long a period and upon the same terms as it had the right to maintain and operate such facilities in their former location.
