The route passes through forested areas to the southeast of Bald Eagle Mountain, heading past the residential community of Nealmont.^[1][3] The road heads into Warriors Mark Township in Huntingdon County and becomes Pennington Road, running through wooded areas with some fields and development and passing through Stover. PA 550/PA 45 Truck continues through agricultural areas with occasional trees ans residences before running through more woodland with some homes. The road heads through a mix of farmland and woods as it comes to the residential community of Warriors Mark, intersecting PA 350. At this intersection, PA 45 Truck turns to the southeast to join PA 350 and PA 550 becomes Centre Lane, heading into more agricultural areas with some trees and homes. The route turns to the northwest before making a turn to the northeast onto Halfmoon Valley Road, continuing through more rural areas.^[1][4]

The road passes through farmland with a few woods and some residential subdivisions as it heads through the communities of Centennial and Stormstown. The route heads into Patton Township and becomes Buffalo Run Road, passing through a mix of farmland and housing developments before heading into wooded areas. In Buffalo Run, PA 550 turns to the east and intersects Atherton Street before passing under I-99/US 220/US 322.
