(a) In general, where road repairs are needed, construction activities may be carried out within a corridor not to exceed 50 feet on either side of the centerline of the existing roadway.

(b) Where bridge replacement repair is to be encountered or safety or capacity considerations warrant relocation or widening, additional from centerline limits shall be given for construction purposes and only as much of the above rights-of-way as is necessary to maintain the transportation facilities shall be retained after the construction is complete. The remainder shall revert to the property owners.

(c) All construction, reconstruction, repair or alterations due to safety or capacity considerations shall be done consistent with safe highway geometric design and in accordance with the “Guidelines to Improve the Aesthetic Quality of Roads in Pennsylvania,” dated June 1978, prepared jointly by the Pennsylvania Department of Transportation and the Pennsylvania Department of Environmental Resources. Should this result in loss of Federal funds in a particular project, the situation will be studied with the view of complying with Federal requirements.
