Keeping America's Historic Covered Bridges Safe for Vehicular Traffic
Snapshot: The Forest Products Laboratory, in partnership with the Federal Highway Administration and the National Park Service is sponsoring a comprehensive research program on Historic Covered Timber Bridges in the United States. This national program's main purpose is to develop improved methods to preserve, rehabilitate, and restore the approximately 800 timber bridge trusses that were developed during the early 1800's, and still remain in-service today.
