About this map

Allegheny Mountains dominate the eastern reaches of this mid-century Pennsylvania landscape, where the Pennsylvania RR and Baltimore and Ohio RR connect industrial centers like McKeesport and Johnstown. This 1954 compilation by the Army Map Service details the post-war transportation network, featuring the prominent route of the Pennsylvania Turnpike as it cuts through the ridges.

The map reveals a region defined by its water management and extraction history, highlighting several flood control projects including Conemaugh River Reservoir and Loyalhanna Reservoir. From the concentrated urban infrastructure of Wilkinsburg to the outlying mining and manufacturing towns like Vandergrift and Osceola Mills, the survey provides a clear view of the mid-20th-century economic corridor between the Monongahela River and the high peaks of Blue Knob.
