Did you know Cincinnati has an abandoned subway system? It's true, although most people don't realize it exists. Cincinnati's Abandoned Subway presents the history and creation of the subway, why it failed, and how the unfinished rapid transit loop impacts the present-day metropolis. This film explores the project's conception in 1916, details of the construction during the 1920s, and its ultimate demise prior to The Great Depression. In the decades since, citizens attempted to revive the subway, but for various reasons it was never completed. Without rapid transit, industry moved out of the area and highways became congested. Cincinnati's Abandoned Subway features commentary from local historians and city engineers, vivid footage of the tunnels, as well as a collection of original construction photographs from the 1920s.
