Any aggrieved party may appeal from the decision of the court on exceptions to the report of the appraisers or the verdict rendered upon jury trial. Such appeal shall not serve to delay the prosecution of the work on the premises in question if the award of the appraisers or jury has been deposited with the clerk for the use and benefit of the surface owner. In case of review or appeal, a certified copy of the final order or judgment shall be transmitted by the clerk to the appropriate county clerk to be filed and recorded.
