Every mobility model brings with it a range of environmental issues: progress in mobility means overcoming some obstacles while at the same time creating new ones. While this matter is already present in the first infrastructure related to the construction of railways in post-unitary Italy, and is then outlined with the expansion of the road network in the years between the two World Wars, it nevertheless took on more precise contours after the Second World War. In light of this new awareness, the debate on infrastructures has seen an expansion of perspective, from the approach dominated by the idea of technological progress and the right to mobility at all costs, to another approach which has added to the debate a new series of topics such as sustainability, landscape protection and, ultimately, the idea of progress as social well-being. This article addresses these issues by reconstructing the debate - animated by specialists in the sector but also by new subjects on the Italian cultural scene, such as the association "Italia Nostra" - which has led to the formation of a new awareness about the environmental effects of the material structures of mobility.
