Motorway infrastructure contributes to climate change and is exposed to its consequences (Shen, 2019). From science and technology studies, climate and motorway infrastructure are an interdependent whole. Motorway infrastructure conception and management evolve according to structural trends in which norms, knowledge, and imaginaries interact. Motorway and automobility systems are confronted to radical adaptation as climate change is reorganizing societies and economies. That is why we mobilize a socio-technical transition approach (Bulkeley et al., 2014) in order to shed light on motorway climate resilience and the way it questions automobility as a heritage. How do "energy and climate" public policies crystallize within the motorway system and modify it? We propose to study Bordeaux ringroad and the way its « solarization » raises harsh discussions in the local political sphere and the media. Not only the roadway, but also the surrounding areas are seen as potential resources for installing solar panels, in line with energy decarbonization objectives. This energy project is competing with other value making perspectives such as adjacent land development or nature and biodiversity preservation. A systemic approach enables to incorporate an energetic dimension within the ringroad governance and understand to what extent it preserves or not the long term stability of the infrastructure and the territory within the planetary limits (Galaz et al., 2012).
