Covered bridges used to cover the American landscape from coast to coast. However, because of various factors including neglect, arson, vandalism, and natural disasters, currently less than 700 to 900 bridges are still in existence today. This book discusses the covered bridge security manual and the remote monitoring of historic covered timber bridges for the prevention of arson and vandalism.
