Earlier, we had the whacked out proposal to tear down the elevated Gowanus Expressway and replace it with a suspension structure along the waterfront. It turns out a photoblogger has already thought the second part through: turning the depressed part of the BQE that runs through Carroll Gardens and Cobble Hill into a canal. The inspiration comes from the Canal de l'Ourcq in Paris and from, of course, Amsterdam. Odds: perhaps a hair better than the Gowanus Skyway.
