Chile has had an incredible economic growth in the last decade, but the urban standards have not increased proportionally. Santiago for example, has no single place where to go for a long walk.
These spaces tend to be associated to the geographical features of cities: rivers, seastrands, hills, but in Santiago, the river has already been used for a highway. The only place left is an old agricultural canal running at the base of the Metropolitan Park, the San Cristobal Hill. It is a ten-kilometer horizontal, continuous path that could be transformed into a pedestrian Promenade.
