When any petition is presented to any court of quarter sessions of this Commonwealth praying for the appointment of viewers, as now provided by law, to view and lay out a public road in any township or townships of this Commonwealth, such petition, and the report of the viewers thereon, shall not be held invalid for the reason that one of the termini named in the petition or in the report is at a point other than in a public highway or place of public resort, where it appears in such petition or report that the other terminus is in a public road and that the road is one necessary for public travel or for the use of a property owner or owners, no longer located on a public highway, by reason of the vacation of the public highway formerly serving such property: Provided, however, That in case one of the termini named in the report is at a point other than in a public highway or place of public resort the finding of the viewers that the road is necessary for public travel or for the use of property owners as above provided shall be subject to the approval of the court of quarter sessions, which may confirm or set aside said finding.
