World Guide to Covered Bridges

The World Guide to Covered Bridges is produced and maintained by the National Society for the Preservationof Covered Bridges (NSPCB). It uses a unique numbering system to identify the individual covered bridges, past and present, from around the world. With funding from FHWA's National Historic Covered Bridge Preservation Program, the National Park Service's Cultural Resources Geographic Information Systems (CRGIS) and Historic American Engineering Record (HAER) have created this online database tool, cataloging over 800 extant and 10,000 lost historic American covered bridges. All bridges are searchable by selected attributes and locations, and existing bridges have been mapped via a variety of sources including GPS and satellite imagery.

The information found in this database comes from several sources. The original source is from the World Guide to Covered Bridges, which is available in print from NSPCB. The Covered Spans of Yesteryear Project has also greatly contributed to expanding knowledge of extant and lost covered bridges. Special thanks to Bill Caswell, Trish Kane, and their team. Considerable information on lost bridges has been generously provided by them and can be researched in detail at
