The Swiss Railway 4 or highway 4 is largely congruent with the National Highway 4 and leads to a total length of 165 kilometers from the border crossing with Germany at Thayngen via Zurich to Altdorf UR. The motorway branch A4a between Cham and Sihlbrugg is officially often referred to as A40.

Route

The A4 starts as a motorway at the border crossing barges on the border with Germany, crossed at Schaffhausen with a cable-stayed bridge over the Rhine and leads from the hallway Lingen, through the Zürcher Weinland, as so -called mini- car train to Kleinandelfingen and further than highway to Winterthur. Between Winterthur and Zurich, the A4 runs together with the removed as A1 motorway. From the Zurich branch east the A4 and A1 run over the so-called northern ring for Limmattaler cross, lead from where the A4 and A3 since 4 May 2009 on the Western Bypass of Zurich; until May 2009 ended this section of the motorway connection Birmensdorf. On 13 November 2009 the section of the A4 in Knonauer office between the branches Zurich West and Blegi was opened in Cham. With 4'680 meters of Islisbergtunnel is the most important building in this section. From Blegi the A4 runs to Schwyz and ends up as a highway to the Mosi tunnel at Brunnen.

The sequel is the National Road N4, also called Axen road that leads from Brunnen to Altdorf in the Canton of Uri, and has a national road third class, the development status of a main road. Opened in 2005, the tunnel bypass Flüelen is again shown as a highway, the access to the A2, however, remained as non -intersecting main road exist.

Expansion projects

Mini motorway corridor Lingen - Kleinandelfingen

On 20 October 2006, the Federal Department of Environment, Transport, Energy and Communications (UVEK ) has approved the design project to expand the two-lane national highway between Flurlingen and Kleinandelfingen in a direction separate four-lane highway Mini. The expansion has cost about 140 million Swiss francs. This meets the large volume of traffic was carried.

In the summer of 2007, the construction work could begin to mini motorway. The release of the removed section was on October 22, 2010 in Kleinandelfingen with an opening ceremony for the public instead. Nevertheless, the developed as a four-lane mini- motorway section is still signaled as a highway.

Full expansion Kleinandelfingen branch of Winterthur North

According to press release from the Federal Office for Roads Authority ( branch of Winterthur ) no earlier than 2018, the expansion of the far lane stretch section of Kleinandelfingen to the branch of Winterthur north direction to a separate four-lane highway is provided ( no mini motorway ). The estimated cost is 310 million Swiss francs (as of 2005). The expansion project was taken up by the Federal Council in Module 2 of the Engpassbeseitungen in the national road network. The planning work was started in January 2010. The necessary funds for the construction can be found in 2013 by federal decree. With the start of construction work, however, is not expected before the year 2018, as the Parliament necessary for this decision is not expected until the year 2016 ..

Galgenbuck tunnel

In May 2007, the government of the canton of Schaffhausen has presented the final design for the Galgenbuck tunnel. The two-lane tunnel serves as a bypass of the municipality Neuhausen Rhine Falls. Currently, more than 25,000 vehicles travel daily through Neuhausen. After commissioning, it will be only half. The tunnel is listed in the master plan since 1970.

From the connection Schaffhausen south of the A4 a total of 1138 meters long tunnel with a slope of 4.5 percent by the Galgenbuck into Unterklettgau to the main road 13 is created. The link to the A4 takes place without crossing. In the service duct below the roadway, a escape tunnel is integrated. Since this law is the transformation of a national road connection, the Federation of reform of financial equalization and division of tasks between the Confederation and the Cantons shall not be held, the cost of about 175 million CHF complete. Construction was carried out in February 2011, with commissioning planned for 2019.

Expansion of Axenstrasse

According to the Federal Roads Authority is to be expanded in several stages in the years 2011 to 2025, the Axen road. Sisikon is relieved by a 4.4 km long tunnel from through traffic. The 2.8 km long tunnel leads from Morsch Acher Ingenbohl by location. By expanding the Axenstrasse is also better protected against falling rocks and other forces of nature.

City Transit Schaffhausen

In the medium term the tunnel Fäsenstaub and the gallery Schoenberg, as well as the further course of the A4 between terminals Schaffhausen Herblingen and Schaffhausen Süd be expanded to Schaffhausen city, from the current two to four lanes, as the city passage poking According to forecasts, in the next few years the capacity limit will. The tunnel is Fäsenstaub including a second tube received ( Fäsenstaubtunnel II) and the gallery Schoenberg be expanded to four lanes. From an implementation is expected by 2020. The federal government has taken with an urgent need for planning in the fall of 2009 the expansion of the city transit Schaffhausen in the list of projects.

The Fäsenstaub and Cholfirsttunnel not meet current safety standards. From 2013, the vents are therefore adjusted, and each created to be a parallel safety tunnel at both tunnel.

Cholfirsttunnel and Rhine Bridge

The construction of a second tube for the Cholfirsttunnel ( Cholfirsttunnel II) and the expansion of the Rhine bridge to four lanes was postponed in the new requirement plan of Federal Department of Environment, Transport, Energy and Communications (UVEK ) for the time being. A realization is possible at most from 2025 or 2030. The bridge across the Rhine and the Cholfirsttunnel therefore remain three lanes for the foreseeable future.

At the federal level, a new version of the " Federal Decree on the national road network " of 21 June 1960, prepared under the title " further development of the national road network " ( WEN ). As part of the consultation, the Federal mid-2008 had the cantons invited to submit comments.

The so-called " New network decision " provides for the adjustment of the road network in the canton of Schaffhausen in the real transit traffic. The ending at the border crossing Bargen former National Road 4 was taken on the German side of any high-performance street, the transit traffic in the direction of Stuttgart was handled by the cantonal highway J15 via the border crossing Thayngen, and there taken by the German federal highway 34 that leads to the Autobahn 81. The J15 was therefore reclassified as of 1 January 2010 from the branching Mutzentäli up to the border crossing Thayngen / Bietingen the National Road, the former N4 was in return from the connection Schaffhausen Swiss image to the border crossing Bargen / Neuhaus am Randen to cantonal highway. With the castling the former J15 was named N4/A4.

The canton of Schaffhausen showed in his opinion to the project agreement in principle, the Schaffhausen Cantonal has (69: 0 Votes ) the opinion on 15 September 2008 unanimously adopted. (: 2'988 23'974 votes ) also confirms Since the cantonal constitution in the case of the planned re-recording of a main road also requires the national road network, a referendum on the opinion has been held on 30 November 2008 and 88.9 % of the votes.

Compared to the previous state with the "New network decision " the national highway network in the canton of Schaffhausen shorter by approximately 7.2 kilometers. The settlements authorized cantonal road network is, however, slightly longer due to the prolonged course of the then N4 and the inclusion of Unterklettgau road ( main road 13), a total of 19.8 kilometers.

The connections to the existing main road were included in the existing numbering system of N4/A4. The future course is:

• Border crossing Thayngen / Bietingen
• Service Area Schwyzerland
• Thayngen ( 1)
• Roost Mountain
• Kesslerloch (1a )
• Roost moss
• Schaffhausen Herblingen ( 2)
• Schaffhausen Swiss image (2a )
• Branching Mutzentäli ( 3)
