"The Historic American Engineering Record (HAER) is pleased to announce the publication of Covered Bridges and the Birth of American Engineering (2015), edited by HAER Historian Justine Christianson and HAER Architect Christopher H. Marston. The book represents the culmination of research under the Federal Highway Administration (FHWA)-sponsored National Historic Covered Bridge Preservation (NHCBP) Program. HAER and the FHWA's Office of Infrastructure Research and Development have maintained a joint research and technology program for historic covered bridges since 2002. This partnership has also included a variety of initiatives including documentation, engineering studies, National Historic Landmark designations, conferences, and a traveling exhibition. This book examines the development of wood trusses and covered bridge construction, profiles the pioneering craftsmen and engineers involved, explores the function of trusses in covered bridges, and looks at the preservation and future of these distinctly American bridges. The editors have collaborated with some of the leading historians and engineers of historic covered bridges in the country to produce this volume. Contributors include Jim Barker, Lola Bennett, Joseph Conwill, Dario Gasparini, Matthew Reckard, and Rachel Sangree. Richard O'Connor and Sheila Rimal Duwadi supplied overviews of the HAER and NHCBP programs, and Michael Harrison and David Simmons provided invaluable editorial assistance."--publisher's website.
