This book starts from the margins: of the city, of infrastructures, of the categories through which we have learned to read the urban. It is born from the experience of growing up alongside a motorway and from the intuition that precisely there — where urbanisation appears incomplete or residual — forms of life, practices and relations are produced, eluding the dominant paradigms of urban planning. This book proposes a critical rereading of urban infrastructures as complex socio-technical assemblages, capable of producing unforeseen spatialities and more-than-human ecologies. Infrastructures, here, are not merely technical or political devices: they are sites of encounter, conflict and above all possibility. Moving from a situated, affective and openly non-neutral perspective, the author adopts an approach that weaves together urban political ecology and everyday practices through a composite methodology. The urban interstices generated by infrastructure thus become the privileged terrain for observing how the urban environment is produced and reproduced daily by human and non-human subjectivities. At the centre of the volume lies the conceptual proposition of urban interstices as spaces of possibility: subordinated and marginalised spaces that, precisely because outside urban normativity, accommodate practices of resignification, experimentation and re-politicisation of the urban. In dialogue with feminist critiques of planetary urbanisation and drawing inspiration from Gibson-Graham's politics of possibility, this book enters the debate of critical urban geography as an attempt to shift the gaze away from zenithal, abstract and universalising readings, towards a grounded perspective attuned to the everyday. Through direct engagement with the interstitial spaces around the SS 554 — the urban motorway that encircles and encloses Cagliari's metropolitan area — the volume shows how urban interstices can be read as spaces charged with socio-political and ecological potential. In these spaces, practices, subjectivities and assemblages call into question the consolidated categories of the urban. Without proposing new models or solutions, the book invites an embrace of the complexity, the contradictions and the possibilities produced around urban infrastructures, taking interstices as the privileged terrain for a critical rereading of contemporary urbanisation.
