Cheswick, PA

Cheswick is an Allegheny County borough of 1,672 people at the 2020 census, packed into about six-tenths of a square mile along the Allegheny River, 17 miles northeast of Pittsburgh. It was incorporated in 1902, after Harry E. Armstrong pushed the borough charter and became its first burgess. The town has always had two levels: a flat strip between river and hill, then the slope rising behind it. Freeport Road, also called Pittsburgh Street in parts of town, runs through that narrow frame.

Cheswick's older map includes the Pennsylvania canal route, the West Penn Railroad, riverfront houses, and land once divided among the Pillow brothers and other early owners. Today Allegheny Valley School District serves the borough, while Harmar Township, Springdale Township, and Springdale Borough border it; Plum sits across the river. The borough's small footprint is the whole story: river, railroad, highway, hillside, and Pittsburgh access all compressed into one Allegheny Valley address. It is a small borough, but the map around it is doing a lot of work.
