The very nature of large-scale infrastructure projects-long design and construction periods, high investment, and impact on social and natural spaces-makes them prone to socioecological and technical conflicts. These conflicts materialize in stories that become keystones in the making of infra-structure. In this article, we analyze the infrastructuring power of stories by drawing on the case of the Chacao Bridge on Chiloe Island in souther Chile, a controversial infrastructure project that has been in the making over the last six decades. We argue that the "absence" of the bridge creates a space for the production of stories on the island's inherited past and imagined future that keeps recurring and growing in the form of myths. Thus, we propose the concept of "mythical infrastructuring" to capture this process. We then con-clude by arguing that the Chacao Bridge project develops its infrastructuring presence over landscape and culture in contradictory ways that cannot be solved technically or symbolically.
