Input: Question: When was the borough that contains the northern terminus of PA 103 incorporated? Passage:PA 103 reaches the residential community of Mattawana, where it passes through two S-curves to the northwest before making a turn to the east at the intersection with John Street, which heads west across the Juniata River to the borough of McVeytown. The route passes through an S-curve to the southeast and runs through farmland, making a turn to the northeast. The road runs through more rural land and winds east, turning northeast to pass through the community of Pine Glen. PA 103 continues northeast through the community of Longfellow before the Juniata River and Norfolk Southern's Pittsburgh Line closely parallel the road to the northwest, with Blue Mountain located to the southeast of the road. The route enters Granville Township and the river and railroad line head further away from the road as it passes through a mix of farmland and woodland with some homes a short distance northwest of Blue Mountain. Farther northeast, PA 103 runs north-northeast through forests with some homes east of the Juniata River. The river curves to the west and the route runs northeast through wooded areas with homes, coming to an intersection with the western terminus of PA 333. Past this intersection, the road heads north-northwest through forests and forms the border between Granville Township to the west and the borough of Juniata Terrace to the east. PA 103 turns northeast onto Delaware Avenue and passes between homes and some businesses to the northwest and woodland to the southeast. The route turns north and leaves Juniata Terrace for Granville Township again as it comes to a bridge over Norfolk Southern's Pittsburgh Line a short distance east of the Lewistown station serving Amtrak's Pennsylvanian train in the community of Lewistown Junction. The road passes north-northwest through residential and commercial areas in Lewistown Junction as an unnamed road, crossing a Juniata Valley Railroad line. PA 103 curves north and crosses the Juniata River into the borough of Lewistown, where it immediately comes to its northern terminus at an intersection with US 22 Bus.
