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.

Weesen-Murg

A special feature is the highway section at Lake Walen. Between Weesen and Murg in 1964, the N3 center was opened as a main road and led by the six tunnels: Ofenegg (370 metres or 1,213.9 ft), Weisswand (460 metres or 1,509.2 ft), Standenhorn (230 metres or 754.6 ft), Glattwand (100 metres or 328.1 ft), Mühlehorn (260 metres or 853 ft) and Stutz (144 metres or 472.4 ft).

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.

.

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.
