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.
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. 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.
This book's quarto landscape format enables the many illustrations to be printed in fine detail. Almost all are historic photo images gleaned from the files of state, county and city engineering and design bureaus. These were originally done for record purposes to document newly built structures. Several pages are devoted to each selected major structure. Yet this is more than a picture book. The author. due to his long experience with such work, is able to succintly discuss each selected structure and its history.
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.

Miss Killikelly’s book is more than a history of Pittsburgh, and all but serves as a history of Allegheny County, of which Pittsburgh has long been the metropolis, and which since the creation of the Greater Pittsburgh — brought about since this book was published — stands more than ever as the expression of the civic activities of its adjacent territory. With the chief facts of the early history of Pittsburgh, especially with those that center around Fort Duquesne, most readers of Pennsylvania history are fairly familiar. The story of these early days lose nothing in Miss Killikelly's retelling. Very marvelous, indeed, has been the growth of this great Pennsylvania city. A record of its population in 1761 gives the number of men as 324, the women 92 and children 47, living outside the garrison; the number of houses with owners' names was 220. At this period the town was divided into a Lower and Upper Town; the "King's Gardens" stretching along the Allegheny, with a background of wheatfields. The residence of the commandant, a substantial brick building within the fort, was the most pretentious house. In 1815 the population had increased to nearly 10,000. The subsequent history of this city is too detailed to be summarized. Miss Killikelly tells the story in ample manner, yet without any overloading of unessential facts. Her pages throb with the active, busy life that has made Pittsburgh so pre-eminently a manufacturing center, and she tells the story of its commercial, industrial and cultural progress with the skill of a practiced writer. Pittsburgh is probably the most misunderstood city in the United States, and Miss Killikelly is entitled to cordial thanks for her entirely readable account.
