be only half the traffic. The tunnel has been listed since 1970 in the master plan. the A4 will create a long tunnel with a slope of 4.5 percent, through the Galgenbuck Klettgau to the main road into the 13th link with the A4 intersections. In the service duct beneath the roadway, an escape tunnel has been built. Since this law concerns the transformation of a motorway connection, the federal government provides, under the new system of financial and division of tasks between the Confederation and the cantons, the full costs of approximately CHF 175 million. Construction is planned for summer 2010, with entry into service in 2014. Reclassifying main road 15 as a national road At the federal level, under the title "development of the national road network" (a revision of the WHO, "the Federal Decree") work has been performed on the national road network since 21 June 1960. During the consultation, the Federal Council in mid-2008 had invited the cantons to submit comments. The so-called "New network decision" provides for the adjustment of the road network in the canton of Schaffhausen before the actual transit traffic. Ending on barges crossing the national highway 4 is obtained on the German side of any road performance, the transit traffic in the direction of Stuttgart, called on the cantonal main road 15 (J15), carried out through the border crossing Thayngen, and then removed from the German federal highway 34, which for Bundesautobahn 81 leads. The main road 15 is, therefore, planned for 1 January 2010 from the junction to the border Mutzentäli Thayngen / Bietingen to be reclassified to the National Road, and the N4 today in return from the connector Schaffhausen Swiss border, to Bargen / Neuhaus am Randen, will be reclassified as the cantonal main road. The castling of the J15 shall be known N4/A4; the N4 is the new main road 4, while the old main road 4 can be in turn re-classified as the side street. 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.
