A hundred years ago this month Cincinnati voted to approve bonds to build a subway system. The city started building it, but it was never completed. Today this is the largest abandoned subway tunnel in the United States.
Jake Mecklenborg wrote the book on the history of the Cincinnati subway. He recently did a podcast to talk about this subway on the Streetsblog Talking Headways podcast. If the audio player doesn’t display for you, click over to listen on Streetsblog.
