Book excerpt: Kentucky is well recognized for bourbon, bluegrass, and the Kentucky Derby. When thinking of covered bridges, the commonwealth is not the state that readily comes to mind. Many of Kentucky's covered bridges were built by such men as Wernwag, Bower, Carothers, Day, Stone, and Long, but many of the names were never recorded or have been lost to time. Kentucky once was home to the longest single-span wooden bridge in the world and to a covered bridge through which a Civil War battle was fought. Time, arson, progress, neglect, and misguided maintenance have spelled the demise of the majority of these structures. Readers of this volume might be surprised to learn that Kentucky once claimed more than 700 timbered tunnels and that over 50 of these survived well into the 1950s. Equally surprising, the commonwealth is still home to 13 of these structures.
