The Ohio River corridor serves as the industrial and transportation backbone of this region northwest of Pittsburgh, where the heavy infrastructure of the early 20th century follows the river's winding path. Major rail lines like the Pittsburgh and Lake Erie RR and the Pittsburgh Fort Wayne and Chicago RR flank the water, connecting established river towns such as Sewickley and Aliquippa. The map reveals the early footprint of Ambridge and the unique layout of Economy, established earlier by the Harmony Society.
