1958 Map of Pittsburgh

About this map

The confluence of the Allegheny River and Monongahela River forms a dense industrial and urban corridor at Pittsburgh, the anchor of a region defined by its steep river valleys and the ridges of the Allegheny Mountains. By the late 1950s, the landscape reflected an era of heavy transport, with the massive Penn Central and Baltimore and Ohio RR networks connecting industrial centers like McKeesport and Johnstown to the steel city. This period also highlights the post-war expansion of regional infrastructure, notably the Pennsylvania Turnpike cutting across the southern half of the sheet.
