Pennsylvania Route 28
highway in Pennsylvania
Pennsylvania Route 28 (PA 28) is a major state highway, which runs for 98 miles (158 km) from Anderson Street in Pittsburgh to U.S. Route 219 (US 219) in Brockway in Pennsylvania in the United States.
From Pittsburgh to Kittanning, it is a 44.5-mile-long (71.6 km) limited access expressway that is named the Alexander H. Lindsay Memorial Highway, and is also known as the Allegheny Valley Expressway. It is named after Alexander Lindsay, a lawyer who lived in South Buffalo and commuted to work in Pittsburgh; he successfully lobbied for the city to be connected to the proposed Keystone Shortway (I-80).
Route description
PA 28 begins adjacent to Downtown Pittsburgh at Anderson Street near the Interstate 279 (I-279)/I-579 interchange and travels north/northeast along the northern bank of the Allegheny River. Until recently the route was a surface street for the first two miles (3.2 km) until the 40th Street Bridge and then an expressway from 40th Street to Kittanning. Upgrades in 2013 made it a limited-access highway throughout its 44.5 miles (71.6 km) in the Pittsburgh metropolitan area from the route's start at I-279 to Rayburn Township, Armstrong County, with Governor Tom Corbett attending the completion ceremony on November 17, 2014.
In Etna, PA 28 interchanges with Pennsylvania Route 8 at exit 5 before departing the Blue Belt, which PA 28 is part of from I-279/I-579 to this point, at exit 6 near Aspinwall. Near Harmar Township, PA 28 meets Pennsylvania Route 910 at exit 11 which provided access to Interstate 76 (the Pennsylvania Turnpike).
From exit 11 to U.S. Route 422 west of Kittanning, PA 28 has eight interchanges, including exits with Pittsburgh Mills Boulevard (exit 12A), Pennsylvania Route 366 (exit 14), and Pennsylvania Route 356 (exit 17), while continuing to parallel the Allegheny to the east. Exit 18 consists of Pennsylvania Route 128 crossing or which used to be old 28 before the expressway.

Why this record matters
The phrase “highway in Pennsylvania” 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.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q1052549. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2013 and 2014.
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.
