The Ohio River corridor serves as the industrial and transportation backbone of this region, where the Pennsylvania Railroad and the Pittsburgh and Lake Erie Railroad flank both banks. In Ambridge, the map highlights the Old Economy (Historical Site), preserving the communal history of the Harmony Society amidst a landscape of mid-century industrial growth. The river itself is a hive of activity, featuring the Dashields Dam, numerous riverside substations, and a Coast Guard Station Light near Osborne.
