1906 Map of Carnegie

About this map

Chartiers Creek and its many tributaries, including Montour Run and Robinson Run, define the industrial and residential topography of this western Pennsylvania region during the early twentieth century. The map documents an intricate lattice of transportation and extraction, centered on the Ohio River and Brunot Island. Heavy rail infrastructure, such as the Pittsburgh Cincinnati Chicago and St Louis RR and the Wabash Pittsburgh Terminal RR, links coal-producing settlements like Cliff Mine to industrial hubs. Notable local institutions are captured, including the Union Church near Gayly and the County Home near Woodville. The southern portion of the sheet transitions into Washington County, showing the established street grids of Canonsburg and Houston alongside rural post offices like Cladden (Gradatim PO) and Lawrence (Hills PO), providing a clear view of the area's development before mid-century suburbanization.
