Since the first covered bridge in America was built across the Schuylkill River in Philadelphia in 1805, Pennsylvania has been the testing ground for some of the world's most unusual and interesting bridges. Shank delves into the lives and works of Burr, Wernwag, Town, Howe, Ellet, Roebling and Modjeski and others who revolutionized bridge-building of the past 5000 years. With 2-color photos and drawings, this book is a must-read for anyone interested in all bridges...covered to suspension...old or new. [from Abebooks.com]
