Pittsburgh is the City of Bridges, and what remarkable bridges they are! The areas challenging topography of deep ravines and mighty riversthe Monongahela, Allegheny, and Ohioset 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. Pittsburghs 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.

3 of 3 people found the following review helpful. Spanning Pittsburgh's Generations By David Hammerstein Bridges connect people and communities. This book, Pittsburgh’s Bridges, connects Pittsburgh’s residents to their past. Todd and Helen Wilson have written an authoritative and meticulous history of Pittsburgh’s architectural and engineering landmarks. The book will likely evoke readers’ memories about the roles Pittsburgh’s bridges played in visits to relatives, family vacations, sporting events, school field trips and other endeavors.Todd and Helen Wilson have enriched Pittsburgh’s historical record. The book traces the bridges’ planning and construction from the standpoint of Pittsburgh’s history. They explain the economic rationale supporting the bridges. It is interesting to note the aesthetic sensitivity that city officials displayed in planning the bridges. They sought beauty as well as function.Readers will likely marvel at the construction accomplishments in an era before computers. The authors describe how bridge design and construction techniques have evolved. They explain how engineers have drawn on the law of physics to achieve strength and durability. Engineers design bridges to optimize the distribution of the load’s weight. Some bridges operate according to the force of compression, whereas others function based on tension.One particularly intriguing section on page 32 deals with suspension bridges. These bridges pose formidable construction and operating challenges. The Seventh Street Bridge embodies a self-anchored design patterned after the Cologne-Deutz Bridge in Germany. Additional discussion of suspension bridges would have enhanced the book.Like downtown’s former venerable department stores, some bridges have disappeared. Pittsburgh has demolished some bridges due to obsolescence. The fortress-like Union Bridge, for example, was destroyed in 1907 because its low clearance blocked Allegheny River traffic.The book spans only 127 pages, yet it amasses numerous facts and photos. The book’s succinct and clear prose supports a quick reading. I recommend it to Pittsburgh’s residents, friends and visitors.
