Providence City Council President David Salvatore is voicing a negative public opinion about a proposed new skyscraper.  Salvatore released a statement yesterday saying the six-hundred-foot Fane Tower could work in another part of the city, but not where it's currently being proposed on former Route 195 land on Dyer Street, where it would require a zoning change.  He says it's not right to require a change in the city's comprehensive plan.  A response from the organization of developer Jason Fane, of New York, indicates Fane isn't interested in building the 46-story tower elsewhere.
