Canton of Schaffhausen
The Canton of Schaffhausen agreed in principle to the project, with the opinion on 15 September 2008 unanimously (69: 0 votes) adopted. Since the cantonal constitution in the case of the planned new recording of a main road into the national motorway network also requires a referendum for an opinion, this was held on 30 November 2008 and by 88.9% Yes votes (23,974: 2,988 votes) also confirmed.
