The Ohio River corridor serves as the industrial and transportation spine for this portion of western Pennsylvania, where the Pennsylvania Railroad and the Pittsburgh and Lake Erie RR flank the banks. Heavy industry and dense urban development concentrate in Aliquippa and Ambridge, the latter featuring the preserved Old Economy Historical Site. Moving away from the river, the landscape transitions into the residential and institutional pockets of Sewickley and Edgeworth, characterized by extensive country club grounds and academies.
