As part of its ongoing commitment to making local records available to the general public, the University of Cincinnati Library has digitized these rapid transit records from the Cincinnati City Engineer Office. Photographs and other items cover the ill-fated attempt by the city to construct a subway system, along with various street improvement projects that took place between the 1920s and 1950s. Visitors can look over the fascinating story of how Cincinnati got started with this proposed subway in the Story section or use an interactive Map to locate individual photographs from this arresting trove.
