Historically, bridges were covered to protect their wooden surfaces from the weather. Today, covered bridges are viewed as charming but rare artifacts of our past. Pennsylvania, the site of the first covered bridge in the United States (over the Schuylkill River in Philadelphia), is the state with the most surviving structures. Benjamin and June Evans visited every bridge for this updated edition, taking new photographs and noting changes since the writing of their 1991 first edition. The builder's name, truss type and number of spans, the condition, length, and width, current owner, and waterway it crosses, specific location, and precise travel directions to each structure are all outlined for each of the 220 bridges documented in this new edition.
