VPSN, talked about the ideology of planning during the 1950s and 1960s. I went on (re: ramble) to talk about the history of the viaducts themselves and highway programs in Vancouver. Michael Green from MGB Architecture and Design talked about the built environment of the area and Gastown, which would have been lost had highways been constructed. Overall, I think it was fairly successful. The MOV put together a podcast of the proceeding - have a listen!
