A3 (Switzerland)
Encyclopedia
The A3 is a motorway in northeast Switzerland
, running diagonally from France toward the southeast border, and passing by Zurich
on the way. The total length of the A3 motorway spans roughly 180 kilometres (111.8 mi), but parts of the road share sections of the A1 and A2 motorways.
The A3 belongs to the Swiss motorway network. It starts at the border in Basel
, where it connects to French motorway A35. From the Wiese Motorway Fork, the route is shared with the A2.
At Augst
, the motorway splits, with the A2 branching off and the A3 continuing past Rheinfelden
and Frick
. After the Bözbergtunnel is the Birrfeld Motorway Fork, near Birmenstorf. Here, the A1 and A3 share the same route as far as Motorway Interchange Limmattal, where the A3 goes towards Urdorf
and the Uetliberg
Tunnel which was opened on May 4, 2009. After Zurich
the motorway weaves through the hills of the south-east bank of Lake Zurich
. It continues along the Walen Lake, and on to Mels
where it ends at a junction with the A13.
The A3 represents (together with a section of the A1) the most important connection between Basel and Zurich, and (together with a section of the A13) the most important connection Zurich–Chur.
The highway section has been extended since 1986 with the opening of the Kerenzerberg Tunnel (5.76 kilometres or 3.6 mi), which handles the road to Murg / Sargans. The old six tunnels and the road on the shores of Lake Walen were converted to unidirectional operation and now form the carriageway to Weesen / Zurich.
and Zurich, the branch South- the last section of the so-called "Western Bypass" - the A3 motorway is continuous between Basel
and Sargans
.
With the opening to traffic of the new section on May 4, two existing sections of highway have been renumbered. The leader in the city of Zurich Autobahnast Limmattal - Hardturm (always officially recorded as N1) is now known as A1 (Switzerland) or A1H (Shuttle Hardturm) rather than A3. The leading out of town Autobahnast Wiedikon - Zurich south, the so-called Sihlhochstrasse is referred to as the new A3W (feeder Wiedikon).
Also initiated, with the opening of the Western Bypass, the first stage of the flanking measures pass the residential areas along the former "West tangent" in the city of Zurich. The existing road trains, which were used for urban transit highway connection endpoints and Wiedikon Hardturm, were temporarily contracted on May 2, each for one traffic lane in each direction. In the following months until the summer of 2010, dismantling will continue of the "temporary" transit routes to district roads (West Street and Sihlfeldstrasse) and urban main roads (Seebahnstrasse und Schimmelstrasse)). In addition to various structural measures that are placed on the axis of incidence via Wollishofen and Albisrieden, additional traffic lights are used to regulate traffic flow in the metering equipment and make the side-traffic into the residential neighborhoods unattractive.
