Iconography started three years ago with two neighboring bridges in the heart of London. Now, for our third birthday, Wade Roush of fellow Hub & Spoke show Sooinsh brings us the story of two Boston bridges, the Longfellow and the Zakim, that share a similar story, though that story has a very different ending. Stick around after Wade's story to hear him and me chat about what makes bridges so iconic and what Spider-Man, Magneto, and Godzilla have to do with it.
