INTERSTIZI URBANI: SPAZI DI POSSIBILITÀ? ESPLORAZIONI URBANE E PRATICHE INFORMALI ATTORNO ALLA SS 554 «CAGLIARITANA»

In this paper, I explore the hypothesis that the interstices around urban motorways could be intended as spaces of creative, political, and performative experimentation outside planning and market logic. Urban interstices can be thought of as the negative of the city and part of a counter-utilitarian discourse, leading to great flexibility in the production of different urban forms.Re-interpreting Gibson-Graham's politics of possibility I re-read urban interstices around motorways as spaces of possibility, in which other spatial forms and dynamics are made visible, conceivable, and thus possible. In the literature on interstices, the emphasis on spatial possibilities is present but never posed in Gibson-Graham's feminist, performative, and transformative terms. The reading of urban interstices as spaces of possibility arises from the exploration of the interstices around the SS 554 "Cagliaritana". In particular, I will provide an understanding of the informal practices taking place in it as non-conflictual political claims towards a different way of producing urban space, that makes the interstices spaces of possibility.
