    Covered bridges are part of the fabric of American history. Although much effort is expended to preserve these structures, many are lost forever. The National Park Service’s Historic American Engineering Record (HAER) has efforts under way to document historic structures. Their Level I documentation is defined in the Secretary of the Interior’s Standards and Guidelines for Architectural and Engineering Documentation and consists of measured and interpretive drawings, large-format photographs, and written historical reports. To assist in this effort, newer technologies need to be explored that can provide as-built records at a faster rate and with more accuracy.
