PA 258 begins at an intersection with PA 108 and PA 173 in the borough of Slippery Rock in Butler County, heading northwest on two-lane undivided North Main Street. The road continues southeast from this point as a part of PA 173. From the southern terminus, the route heads past a few businesses before heading into residential areas. PA 258 runs through less dense areas of housing before crossing into Slippery Rock Township and becoming Mercer Road. The road continues into agricultural areas with some woods and homes, crossing Wolf Creek and passing near Christleys Mills.^[1][2]

PA 258 enters Liberty Township in Mercer County and becomes Mercer Butler Pike, running through farmland and woodland with some residences and passing through North Liberty. The road continues through more rural areas, passing through Valcourt and Amsterdam. The route heads into Springfield Township and comes to an intersection with PA 208 in London. At this point, PA 258 turns west to form a concurrency with PA 208 on South Center Street Extended, a five-lane road with a center left-turn lane. The road heads through business areas and comes to an interchange with I-79, at which point it becomes Leesburg Grove City Road. A short distance past the interchange, PA 258 splits from PA 208 north of the Grove City Premium Outlets by turning north onto two-lane undivided Butler Pike, turning east past more commercial establishments. The road turns north into wooded areas and runs a short distance to the west of I-79 before curving northwest. The route heads through more wooded areas with some farm fields and homes, passing through Blacktown before heading into Findley Township. PA 258 continues through more rural areas with some residences, passing under I-80. The road runs through more farmland and woodland with a few homes, passing north of State Correctional Institution – Mercer and crossing the Neshannock Creek into East Lackawannock Township.^[1][3]

The route heads into residential areas and turns north onto South Pitt Street, entering the borough of Mercer. Here, PA 258 passes more homes and comes to an intersection with PA 58 in the downtown area. At this point, the route turns west to join PA 58 on a one-way pair that follows North Diamond Street northbound and South Diamond Street southbound, passing through the commercial downtown with the Mercer County Courthouse located between the two streets. At the end of the one-way pair, the two routes come to an intersection with US 19 and US 62. Here, PA 58 turns north to follow US 19 and US 62 on North Erie Street while US 62 and PA 258 continue west on two-lane undivided West Market Street.
