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. Pittsburgh's Bridges takes a comprehensive look at the design, construction, and, sometimes, demolition of the bridges that shaped Pittsburgh, ranging from the covered bridges of yesterday to those that define the skyline today.

Documents Pittsburgh's status as the "City of Bridges" (it has more bridges at 446 than any other city in the WORLD). Includes background on the history and types of bridges; profiles Pittsburgh's bridge pioneers (Roebling, Lindenthal, Ferris, Richardson); explores historical and contemporary bridges; looks at the variety of bridge types and styles; describes several unique Pittsburgh bridges; and includes 10 self-guided tours.

Bob Regan mines the rich vein of Pittsburgh¿s history by continually finding a new lens through which to view the past. His previous two books¿The Steps of Pittsburgh and The Bridges of Pittsburgh¿were received with acclaim, drawing fans from the Pittsburgh diaspora around the world. The Names of Pittsburgh does the same as Regan explores the names of the men and women¿not to mention scientific paraphernalia, patents, astronomical terms, grape varietals, et al.¿from the region¿s history which dot the landscape. Each provides a segue into a broader discussion of some fascinating aspect of Pittsburgh¿s past.

Western Pennsylvania's infrastructure is renowned for traversing valleys, mountains, rivers and everything in between. Early surveying in the region delineated state and local boundaries that allowed for the mapping of canals, railroads and roadways. Engineers developed bridges, ground transportation systems and airports that linked Pittsburgh to the world. Frequently overflowing rivers transformed into reliable navigation passageways. Drinking water and wastewater treatment systems allowed development and population to flourish, leading to investments in iconic buildings. Join expert civil engineers and professionals as they narrate the story of Pittsburgh and the surrounding region's engineering triumphs.
