The Ohio River corridor serves as the industrial and transit spine for this region north of Pittsburgh, where the Pennsylvania System and the Pittsburgh Fort Wayne and Chicago RR hug the riverbank through Ambridge, Conway, and Baden. This early 20th-century landscape is defined by its transition from dense riverfront settlements to the upland plateaus of Marshall and Cranberry townships.
