This research project conceives infrastructure as a socio-material assemblage of both human and non-human associations—it bridges the material and immaterial, the visible and invisible, and yet, at times, it also dissolves these distinctions. Our research addresses these realities, in India and Vietnam, by attending to the scalar dimensions of infrastructure and their entanglement through rural and urban contexts, and across national borders. We consider how infrastructure of mobility – road networks and wireless communication technologies – encodes aspirations, and how it aligns or differs from its function as claimed by the state. By focusing on the infrastructure of mobility, our research will assess how marginalised communities in India and Vietnam integrate, but also subvert, elements of technological modernity to their livelihoods.
