“Bridges” surveys these ubiquitous structures, from familiar monuments to modest designs. It categorizes American bridges from coast to coast in terms of four fundamental structural types (beam, arch, truss and suspension) as well as movable bridges (swing, lift and bascule). The volume includes “A Call for Preservation” of the engineering heritage of the American bridge, written by Eric DeLony, former chief of the Historic American Engineering Record at the National Park Service. The May 9th program will feature illustrated presentations by the authors, book signings and a reception.
