Transfer Bridge Circa 1905

Between 1890 and 1915 the only 30 transfer bridges in the entire world were built. This bridge was opened in Duluth Minnesota during the summer of 1905. The modified bridge still stands today - transformed into a lift bridge during the 1930's. With a series of historic photos plus images of some pages from the original drawing package I was able to accurately create CAD models of the 1905 bridge structure.
