Pittsburgh's Bridges
O ovoj e-knjizi
Pittsburgh is the "City of Bridges," and what remarkable bridges they are! The area's challenging topography of deep ravines and mighty rivers - the Monongahela, Allegheny, and Ohio - set the stage for engineers, architects, and contractors to conquer the terrain with a variety of distinctive spans. Many were designed to be beautiful as well as functional. While other cities may have one signature bridge, Pittsburgh has such a wide variety that no single bridge can represent it.
