Pennsylvania Route 512
State highway in Northampton County, Pennsylvania, US
Pennsylvania Route 512 (PA 512) is a 26.1-mile-long (42.0 km) state route in Northampton County in the Lehigh Valley region in eastern Pennsylvania. The southern terminus is at U.S. Route 22 (US 22) north of Bethlehem in Hanover Township. The northern terminus is at PA 611 in Upper Mount Bethel Township. The route heads north from US 22 to Bath, where it intersects PA 248. From here, PA 512 continues northeast and intersects PA 946 in Moorestown before it reaches an interchange with the PA 33 freeway in Wind Gap. The route heads east through the northern Northampton County boroughs of Wind Gap, Pen Argyl, Bangor, and East Bangor, intersecting PA 191 in Bangor. It then continues east to PA 611.
PA 512 was originally designated by 1928 to run from PA 12 (now PA 191) in Hecktown north to PA 12 in Wind Gap. In the 1930s, the southern terminus was realigned to US 22/PA 12 at Center Street and Elizabeth Avenue in Bethlehem, with PA 946 replacing the route between Hecktown and Moorestown. The road between Wind Gap and Bangor was originally designated PA 202 in 1928 before being renumbered to PA 702 in 1935 to avoid conflict with US 202.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Pennsylvania Route 512”, the useful work is to connect “state highway in Northampton County, Pennsylvania, US” to the records capable of establishing context and consequence.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Oct 16, 2025. The linked authority identifier is Q1415500. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1928 and 1935.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. 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.
