The confluence of heavy industry and suburban expansion defines this landscape along the Monongahela River and Allegheny River. While traditional rail-and-river transport remains central, with the Penn Central and Baltimore and Ohio railroads tracing the valleys, the 1969 revisions highlight the rapid growth of communities like Monroeville and Garden City. Institutional landmarks such as the Gateway High Sch and the East Pittsburgh Airport appear alongside older religious sites like the Beulah Ch and Hebron Cem.
