Source-derived summary

Pennsylvania Route 258 (PA 258) is a 27-mile-long (43 km) state highway located in Butler and Mercer counties in Pennsylvania. The southern terminus is at PA 108/PA 173 in Slippery Rock. The northern terminus is at PA 18 in Clark.

Route description

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.

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.

Editorial summary

Begin with the source’s own compact description: “Pennsylvania Route 258” is state highway in Pennsylvania, US. The dossier treats that line as a proposition to test through Pennsylvania, Route and State, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 176-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Pennsylvania, Route and State is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “state highway in Pennsylvania, US” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Oct 24, 2025. The linked authority identifier is Q1173292. None of the 0 selected statements returned an explicit reference.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
