The Allegheny River defines the industrial and residential corridors of this region, separating Allegheny Co from Westmoreland Co. Along its banks, the towns of Tarentum, New Kensington, Springdale, and Oakmont demonstrate the dense riverfront development characteristic of the mid-20th century, supported by the Conrail and Bessemer and Lake Erie railroads. Notable infrastructure like Lock and Dam No 3 and the Hulton Br manage the river's transit, while the legendary Oakmont Country Club and Allegheny County Regional Park provide significant green space amidst the expanding suburbs. Purple overprint highlights the growth of residential tracts like Magill Heights and Fairview Heights as they moved away from the industrial river edge toward the hills. Smaller communities like Harwick and Indianola maintain their identity, often centered around local institutions like St Anthonys Sch or Walter Chapel.
