Historically, covered bridges were designed 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), remains the state with the most surviving structures. Ben and June Evans revisited every one, criss-crossing the state during the spring and summer of 2000, taking new photographs and noting changes since 1991. 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.
