1907 Map of Pittsburgh

About this map

The Monongahela River and Allegheny River converge at the heart of this industrial landscape, where steep topography forced dense urban development into the valleys and onto prominent heights like Squirrel Hill. Surveyed at the turn of the century, the map reveals a region dominated by its transport network, from the heavy rail lines of the Pennsylvania RR and Pittsburgh and Lake Erie RR to the winding river divisions. The expansion of steel and manufacturing is evident in the sprawling growth of Homestead, Braddock, and Duquesne. Away from the riverbanks, residential life is marked by numerous large burial grounds, including the Allegheny Cem and Homewood Cem, while smaller settlements like Turtle Creek and Wilmerding cluster around the rail junctions that fueled the local economy during this era of rapid growth.
