The Ohio River corridor serves as the industrial and transportation backbone of this region northwest of Pittsburgh, where the Pittsburgh Fort Wayne and Chicago RR and the Pennsylvania RR line the riverbanks. Early 20th-century development is concentrated in river towns like Ambridge, Sewickley, and Freedom, while the interior townships of Cranberry and Marshall remain characterized by a network of rural roads, small schools like the Boggs School, and country churches such as Dutilh Church.
