Source-derived summary

Pennsylvania Route 641 (PA 641) is a state route that is located in Central Pennsylvania in the United States. The route is 57.9 miles (93.2 km) long and runs from U.S. Route 522 (US 522) near Shade Gap east to US 11/US 15 in Camp Hill.

PA 641 heads east from Shade Gap in Huntingdon County and immediately crosses PA 35 before it heads across Tuscarora Mountain into Franklin County. The route intersects PA 75 in Spring Run before it crosses Kittatinny and Blue mountains and reaches a junction with PA 997 in Roxbury. PA 641 heads into the agricultural Cumberland Valley and enters Cumberland County, where it intersects PA 696 in Newburg and PA 233 in Newville before reaching Carlisle.

In Carlisle, the route runs concurrent with US 11 and PA 74 on High Street and crosses PA 34 in the center of town. East of here, PA 641 has an interchange with Interstate 81 (I-81) and heads to Mechanicsburg, where it intersects PA 114. The route continues through the western suburbs of Harrisburg and has an interchange with US 11/PA 581 before ending in Camp Hill. PA 641 has a truck route, PA 641 Truck, that bypasses the winding stretch across Kittatinny Mountain.

PA 641 was designated in 1928 to run from PA 74 in Carlisle east to US 11 (Carlisle Pike) in Camp Hill.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as state highway in Pennsylvania, US. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Oct 24, 2025. The linked authority identifier is Q1499092. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1928.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
