Bridges

Take a tour through time and learn about the exciting engineering developments that allowed the primitive bridges of ancient man evolve to the masterworks of today. This unique treatment, showing the large variety of bridge forms, is illustrated with postcards, archival photographs, and technical drawings and diagrams. These detailed images show stone arch, suspension, movable, and many more bridges. Laymen and engineers alike are certain to come away with a better understanding of the role of bridges in our built environment from the expert explanations of bridge types, materials, and construction to amusing anecdotes associated with these structures. Landmark bridges, construction methods, the interstate system, railroad bridges, and even bridge disasters are all documented in this technical record of civil engineering challenges and feats.
