Pennsylvania Route 222
highway in Pennsylvania

Pennsylvania Route 222 (PA 222) is a 4.482 mi (7.213 km)-long state highway located in Allentown and its surrounding suburbs in the Lehigh Valley region in eastern Pennsylvania.
Most of the route runs along Hamilton Boulevard. In Center City Allentown, the route is aligned along West Hamilton, West Linden, and West Walnut Streets. The southern terminus of the route is at Interstate 78 (I-78)/PA 309 in Dorneyville, where the roadway changes designation from PA 222 to U.S. Route 222 (US 222). The northern terminus is PA 145 in Allentown.
Since the city's founding in the 18th century, Hamilton Street was among the first streets constructed in the city and served as the main street in Center City, Allentown. Hamilton Street and Hamilton Boulevard became part of the William Penn Highway in 1916, PA 3 in 1924, and US 22 in 1926. In 1931, US 22 was routed to a new alignment to the north, and Hamilton Boulevard and Hamilton Street west of 15th Street became a part of US 222. In the 1950s, US 222 was rerouted to bypass Allentown, leaving Hamilton Boulevard and Hamilton Street through the city unnumbered.
In 1984, the Pennsylvania Department of Transportation (PennDOT) proposed extending US 222 from I-78/PA 309 to Center City Allentown, where it would end at PA 145.

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 Mar 15, 2026. The linked authority identifier is Q1172993. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1916, 1924, 1926 and 1931.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
