Rochester Abandoned Subway
In 1927 the Rochester Industrial and Rapid Transit Railway opened and ran along the old Erie Canal which was redirected earlier. The city wanted to redirect the passage and create a freight exchange as there were many railroads in the area. The subways total length was less than 10 miles and it was serviced only until 1956 (the subway was actually hampered because the Erie Canal route really didn't accommodate intra-city transit). The subway has been mostly filled in but a segment downtown is still accessible even though most entrances are gated. Lack of funding has left the remaining tunnel unfilled.
