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 Zürich. 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.
