4. Discussion
The case study shows that interests may be an organising devise in the Conferenza di Servizi, but interests were replaced with concerns in the activity of building the motorway. It also shows that even if it was possible to identify interests and stakeholders for the Conferenza, as a matter of design, when in action, the mountain made new actors appear. This does not mean that the Conferenza is not important; it is an obligatory passage point where parties meet and make choices about common problems related to the project. Yet, it did not create closure. The mountain developed concerns about, not only the roads, but also housing, money, and indeterminable responsibilities. It also raised concerns about ways of listening to the mountain by controversies of instrumentation for monitoring the mountain. Last, it raised concerns about the logic of the construction per se. Above all, everything happened under conditions where causality was always under scrutiny and debate.
