A4 motorway

The A4 motorway in Switzerland begins from Schaffhausen, in northern Switzerland, and travels southward into central Switzerland.
The A4 starts out as an Autostrasse road at the border crossing Bargen / Neuhaus am Randen, at the border to Germany, crossing a suspension bridge at Schaffhausen over the Rhine, and continues through Zurich's wine country to Winterthur. Between Winterthur and Zurich, the A4 runs together with the developed A1 Autobahn . From Zurich the branching east from the A4 and the A1 via the so-called Nordring the motorway interchange Limmattal, the motorway runs from where the A4 and A3, since 4 May 2009, joined to the Western Bypass of Zurich; until May 2009 this section ended for the motorway junction Birmensdorf. In November 2009 the opening of the A4 in Knonaueramt between the branches of Zurich West is planned, at Blegi Cham. From Blegi, the A4 goes on to Schwyz and ends as an Autostrasse road at Brunnen.
