During the years of my youth, near the fateful ’68, there is no doubt roads were considered one of the essential factors for the economic, social and cultural development of the human society. Only benefits were expected from a new road. In the two decades between 1970 and 1990 this assumption has been gradually called into question up to 2000, when some thinkers and environmental associations started contest about any new road construction. My work as a young and enthusiastic engineer before and later on as a professor trainer of new engineers was deeply called into question; this questioning was about its meaning and its ethic consequences. After all, it was the same problem that bioethics had created in biology and medicine. This science tries to solve problems arising from the relation between the applications of technical-scientific research from one side and the consequences on human life from the other one.
