Ind. Code § 8-20-1-72
Any person aggrieved by any decision of the executive of any county in any proceeding relating to highways may appeal within thirty (30) days to the circuit court, superior court, or probate court of the county by filing a bond. If the proceedings involve more than one (1) county, the appeal shall be filed in the circuit court, superior court, or probate court of the county where the proceedings were first instituted. The auditor of each county, when notified of an appeal by the auditor of the county where the appeal is filed, shall transmit to the clerk of the court a transcript of all the proceedings in the county. After the appeal is decided, the clerk shall notify the auditors of all interested counties. The appeal shall be tried de novo. The court may make a final determination on the cause appealed, or may refer the case back to the county with directions on how to proceed.
