Finding aid encoded by Cheri Thies, July 2012 Finding aid written in English. OVERVIEW Minnesota Historical Society Minnesota. Bridge Division. Bridge photographs and negatives. [1920s]-[1970s]. Materials in English. Photographs and negatives of 4,624 structures (e.g., vehicle bridges, railroad bridges, pedestrian bridges, culverts). It is important to note that these sets do not represent the state's entire bridge population and that some are no longer extant. 6.95 cubic feet (9 boxes and 1 partial box). See Detailed Description for shelf locations. SCOPE AND CONTENTS

Also, the two sets are not exact duplicates. Some bridges may be represented only by photographs, while others are only found in the negatives. Similarly, accompanying documentation varies on an item-by-item basis - photographs may or may not be marked with information on the back side, while negative envelopes may or may not carry handwritten or typed notations and photographic exposure data. Information that may be noted includes bridge location, date, and photographer.

The photographs and negatives are accompanied by two item lists, one arranged by bridge number, the other by location. They were generated from a bridge database supplied by the Minnesota Transportation Department. Information recorded includes county, year of construction, route type, route number, and crossing information. Note, however, that not all bridges represented in the photographs and negatives are included in the database.
