Route description
PA 488 begins at an intersection with PA 65/PA 288 in the borough of Ellwood City in Lawrence County, heading east on two-lane undivided Fountain Avenue. The road passes through residential areas before heading into commercial and industrial areas, turning southeast onto Portersville Road. The route heads into the community of Burnstown in Wayne Township and running between woods to the north and homes to the south. PA 488 forms the border between Wayne Township to the north and Ellwood City to the south as it passes to the north of a steel mill. The road turns east and enters the borough of Ellport, passing a mix of residences and businesses. The route crosses the Connoquenessing Creek into Perry Township and heads into more wooded areas of residential development. PA 488 turns to the northeast and crosses the Slippery Rock Creek back into Wayne Township, passing through Wurtemburg. The road crosses the creek again and heads back into Perry Township, entering wooded areas with some fields and homes. The route continues northeast through more farmland and woodland with some homes.

PA 488 enters Muddy Creek Township in Butler County and becomes West Portersville Road, soon heading into the borough of Portersville as it passes through more rural areas. The road turns east and passes homes, reaching an intersection with US 19. At this point, PA 488 turns south to form a concurrency with US 19 on Perry Highway, a three-lane road with a center left-turn lane that runs through residential and commercial areas. PA 488 splits from US 19 by turning east onto two-lane undivided East Portersville Road. The road passes a mix of farmland and homes before crossing back into Muddy Creek Township and coming to an interchange with I-79. A park and ride lot is located at the southwest corner of this interchange. Past this interchange, the route heads into wooded areas with some farms and residences.

The road heads southeast into more farmland and woodland, crossing into the borough of Prospect and becoming Main Street. The route passes through residential areas with some fields and trees, turning east into more dense areas of homes and crossing PA 528.
