CINCINNATI SUBWAY

"Abandoned tunnels are often the object of urban legend, but Cincinnati is in fact the site of the country's largest abandoned subway tunnel. But 'abandoned' is not quite the word, as construction slowed to a stop in 1925 before even half of the 16 mile line was completed. Seven miles between Cincinnati's central business district and the industrial suburb of Norwood were tunneled, bridged, or graded, but no track was laid and no subway cars were ordered. No passengers ever rode between the six stations that were built."
