Industrial activity and established riverfront communities define the Ohio River corridor at the start of the twentieth century. Along the eastern bank, the concentrated development of Sewickley and Ambridge contrasts with the industrial footprint of Aliquippa and Woodlawn on the opposite shore. The Pittsburgh and Lake Erie RR and Pennsylvania System tracks hug the river, serving as the primary arteries for this burgeoning manufacturing district.
