About this map

The industrial confluence of the Allegheny River and Monongahela River forms the heart of this early 20th-century urban landscape. The dense street grid of Pittsburg spreads eastward into Wilkinsburg, revealing a city shaped by its riverfronts and rising topography. Large-scale public spaces such as Highland Park and Schenley Park provide relief from the industrial corridors, while the massive Allegheny Cemetery stands as a significant landmark in the city's north.

Downriver, the landscape is defined by its steel-producing centers and heavy rail infrastructure. The Pennsylvania R R and Pittsburg and Lake Erie R R trace the banks, serving manufacturing hubs like Homestead, Braddock, and Rankin. Smaller settlements like Hoboken and Sandy Creek dot the valley slopes, connected by a intricate web of lines including the Baltimore and Ohio R R. The map also captures the confluence where the Youghiogheny River meets the Monongahela, highlighting the river-based economy that fueled the region's growth.
