New Alexandria, PA

New Alexandria is a Westmoreland County borough on Loyalhanna Creek in the western part of the county, about four miles northeast of Greensburg. The borough formed from New Alexandria and Denniston's Town, which were joined when the community was incorporated in 1834. The creek valley and the two-sided street pattern still give the borough its basic shape. An old covered toll bridge crossed Loyalhanna Creek in 1832, linking the main streets on either side and making the waterway part of the town's daily geography.

The bridge was bypassed by the William Penn Highway, now U.S. Route 22, in 1950. That highway places New Alexandria on the route between Pittsburgh and Johnstown, while local roads continue toward Latrobe, Greensburg, and the surrounding Westmoreland hills. The borough's history page also traces the area through early landholders, the first Derry Township borough, and the old creek crossing. New Alexandria remains a compact place where a nineteenth-century borough center meets a major regional highway.
