On May 12 and May 13 Mayor John Tory repeatedly cited the city of Rio de Janeiro as an example of how great cities deal with elevated expressways by utilizing the areas underneath for skateboard parks, markets etc. In this video the mayor explains to the media the opportunity to do the same in Toronto. Also in this video is the 2013 demolition of an elevated expressway in Rio de Janerio (Elevado da Perimetral flyover), part of a plan by Rio's mayor to make their Port Lands more vibrant and people friendly. http://www.bloomberg.com/news/articles/2015-02-20/mayor-bets-big-on-rio-de-janeiro-s-broken-down-port-area-cities
