I don't know much about it or its history, but somebody on here might? I have heard
that Cincinnati, Ohio started a subway system that was never finished. As you drove
through the city on I-75 I had read, and I could see what looked like tunnel portals
up on the east side of the road. I have not seen them lately, but the Interstate,
like those in most cities, is constantly under reconstruction.
