Historic American Engineering Record (HAER)

The Historic American Engineering Record (HAER) is a program created in 1969 to document the country's significant engineering and industrial sites. It is part of the National Park Service and aims to preserve the history of America's technological achievements. HAER produces detailed drawings, photographs, and written histories of important structures, such as bridges, factories, and canals. This documentation helps educate the public, supports preservation efforts, and provides valuable resources for researchers and historians interested in America’s engineering heritage.
