At one time, 51 covered bridges had provided a safe and economical way to cross the waterways of Berks County. Today there are 5 remaining. In this PowerPoint program presented by local author and Theodore Burr Covered Bridge Society of PA historian Fred Moll, we will take a trip back in time to view bridges past and present, learn about toll bridges, why they were covered and why they were painted red.
