1958 Map of Pittsburgh

About this map

Industrial valleys and Appalachian ridges define this regional landscape at the end of the 1950s, centered on the confluence of the Allegheny River and Monongahela River. This 1:250,000 scale map captures the dense urban and industrial corridors stretching toward Butler, Greensburg, and Connellsville. The steel-era infrastructure is prominently displayed, from the heavy rail networks of the Baltimore & Ohio RR and New York Central RR to the path of the Pennsylvania Turnpike cutting across the southern portion of the sheet. Beyond the river towns, the terrain rises into the Allegheny Mountains, where numerous conservation areas like Laurel Hill State Park and Linn Run State Park mark the high ridges. This map provides a vital overview of Western Pennsylvania's mid-century economic geography, showing the spatial relationship between coal-country settlements like Johnstown and the regional hubs of Altoona and Kittanning.
