main in the subway could be removed easily. There is also an escape clause in Ordinance No. 154-1956 that states, "in the event said section of the rapid transit subway is, at some future date, needed for rapid transit purposes, the Water Works shall remove said main at its sole cost." In the 1960s, Hamilton county proposed the Liberty Street station be turned into a bomb shelter. However, the result was a very weak attempt at a fallout shelter that would not have provided much for those residing in it. There were also suggestions by investors to turn the tunnels into passages for freight trains, but that project failed due to the sharp turns existing in the tunnels that freight trains could not handle. The subway bonds were paid off in 1966 at a total cost of $13,019,982.45. Around that time Meier's Wine Cellars Inc. wanted to use the subway tunnels to store wine, as well as install a bottling operation to draw tourists, but it fell through due to a lack of proper building codes. In the 1970s Nick Clooney wanted to turn parts of the tunnel into an underground mall and a night club, but that fell through early on due to insurance issues. In the 1980s the city pitched the tunnels to Hollywood filmmakers as a location to shoot subway scenes. In particular, the location was presented to the makers of Batman Forever, but as of 2008 the tunnels had not been used in any feature films. In 2002, a regional light rail system was proposed to use the tunnels; the system would cost $2.6 billion and take thirty years to build. The tunnels were favored because they were in an ideal location, they could easily be used to connect the east side and the west sides of Cincinnati, and they would have saved the city at least $100 million in construction costs at the time. The light rail plan, called MetroMoves, proposed a tax levy that would have raised sales tax in Hamilton county by a half-cent. The plan was voted down by more than a 2-to-1 ratio, with 68% opposing MetroMoves. Still, an underground portion of the Riverfront Transit Center was built to serve the proposed, unbuilt MetroMoves lines; this transit center was later served by another Cincinnati streetcar line, the Cincinnati Bell Connector. In 2017, shortly after the 100th anniversary of the tunnel construction,
