Photographic Prints and Negatives, 1921 - 1943, undated

Granville Thompson's photographs document Indiana highway bridge construction projects dating from 1921-1943. Approximately 41 bridge construction projects are covered, at around 33 location sites in Indiana. The collection includes approximately 398 photographic prints and 219 negatives. Many of the original structures in the photographs no longer exist.

The photographs were primarily taken by Thompson using a Kodak IA folding camera, on 116 film. (The camera was later donated to the Kodak Museum by Robert Thompson). A small number of the photographs were taken by J. B. Manson, M. M. Porter [H. H. Porter?], or "Mr. Wooley," of the U.S. Bureau of Roads. Most of the images are 2.5" x 4.5" in size. Not every print has a negative, and not every negative has a print.

Most of the images are identified by location and/or project or contract number. There may be state records of the contracts or projects that will provide further identification for each image. The project numbers tend to begin with the number of the state road or highway included in the project.
