About this map

The Allegheny River and Monongahela River converge at the heart of industrial Pittsburgh, anchoring a dense network of river-and-rail infrastructure in the late 1950s. This survey illustrates the mid-century industrial footprint of Western Pennsylvania, where the Pennsylvania RR and Baltimore and Ohio RR connect major manufacturing centers like McKeesport, Johnstown, and Altoona. Beyond the urban cores, the landscape is defined by the sharp ridges of the Allegheny Front and the Pennsylvania Turnpike cutting across the terrain toward the east.

Water management and recreation are prominent through features like Conemaugh River Lake and Crooked Creek Reservoir, which speak to the era's focus on flood control and public works. From the glass-making centers of Jeannette and Ford City to the southern coal and coke regions near Connellsville, the map captures a mature industrial landscape at its peak before significant late-century economic shifts.
