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.

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.

Beyond the Lab and the Field analyzes infrastructures as intense sites of knowledge production in the Americas, Europe, and Asia since the late nineteenth century. Moving beyond classical places known for yielding scientific knowledge, chapters in this volume explore how the construction and maintenance of canals, highways, dams, irrigation schemes, the oil industry, and logistic networks intersected with the creation of know-how and expertise. Referred to by the authors as “scientific bonanzas,” such intersections reveal opportunities for great wealth, but also distress and misfortune. This volume explores how innovative technologies provided research opportunities for scientists and engineers, as they relied on expertise to operate, which resulted in enormous profits for some. But, like the history of any gold rush, the history of infrastructure also reveals how technologies of modernity transformed nature, disrupting communities and destroying the local environment. Focusing not on the victory march of science and technology but on ambivalent change, contributors consider the role of infrastructures for ecology, geology, archaeology, soil science, engineering, ethnography, heritage, and polar exploration. Together, they also examine largely overlooked perspectives on modernity: the reliance of infrastructure on knowledge, and infrastructures as places and occasions that inspired a greater understanding of the natural world and the technologically made environment.
