The Ohio River corridor serves as the industrial and transportation spine of this region northwest of Pittsburgh at the opening of the twentieth century. Dense rail networks, including the Pittsburgh Fort Wayne and Chicago RR and the Pittsburgh and Lake Erie RR, trace the riverbanks, connecting a string of established river towns like Economy, Ambridge, and Sewickley. This era marks the height of the river-and-rail economy, evident in specialized features such as Dam No 4 and the Montour Junc.
