Bridge Preservation & Awareness
Protecting Pennsylvania's Historic Covered Bridges for Future Generations
Why Preservation Matters
Pennsylvania's covered bridges are irreplaceable treasures of American history and craftsmanship. Built primarily in the 19th century, these wooden structures represent the ingenuity of early American engineers and the communities that depended on them. With only 209 authentic covered bridges remaining in the Commonwealth, each one is a precious link to our past.
The Theodore Burr Covered Bridge Society of Pennsylvania is dedicated to promoting awareness and active participation in the preservation and restoration of these historic structures. Through education, advocacy, and community engagement, we work to ensure that these bridges survive for generations to come.
Many covered bridges face threats from flooding, neglect, vandalism, and the pressures of modern traffic. Without ongoing attention and resources, these irreplaceable landmarks can be lost forever. Your support and involvement make a real difference.
Threats to Covered Bridges
Flooding & Weather
Severe storms and flooding events can damage or destroy covered bridges. Many historic bridges have been lost to floodwaters over the decades.
Structural Deterioration
Without regular maintenance, wooden timbers decay over time. Routine inspection and repair are essential to keeping these structures sound.
Vandalism & Arson
Covered bridges are unfortunately vulnerable to vandalism and arson. Community awareness and vigilance are key to protecting these landmarks.
Traffic & Overloading
Modern vehicles can exceed the weight limits of historic bridges. Proper signage and enforcement help protect bridges from structural damage.

The Theodore Burr Legacy
Our society is named in honor of Theodore Burr (1771–1822), the American bridge builder who patented the Burr Arch Truss in 1817. This innovative design — combining a multiple kingpost truss with a long arch — became one of the most widely used covered bridge designs in Pennsylvania and throughout the northeastern United States.
The Burr Arch Truss proved remarkably durable, and many bridges built with this design still stand today. By preserving these structures, we honor Theodore Burr's engineering legacy and the communities that built and relied upon them.
