Close up view of the South Fork railroad bridge, circa 1902.

This was taken during the track elevation project, and, of course, huge bridges like this one had to be raised as well. The bridge might have appeared somewhat small in the last picture, as it was set against an enormous building. Here, however, the personnel in the picture give a better idea of the scale of the bridge.
