Reposting this announcement originally from June 3, 2010 to correct a bad link. The Archives Service Center added 511 new images to the Pittsburgh City Photographer online image collection. Scanned from glass plate negatives by the ULS Digital Research Library, these images document significant changes in roads, infrastructure, and neighborhoods in Pittsburgh from 1911-1912. The images feature prominent projects such as the lowering of the hump in Downtown as well as the continued efforts to provide the city with modern water treatment, bridges, and roads. Photographic copies of plans and drawings are also included.
