Upgrade of the Breite Wallisellen underpass

Project Description

A new cycle and pedestrian underpass is taking shape in the area around the junction between Neugutstrasse and Breitestrasse, along with changes to Neugutstrasse in the direction of the Hofstrasse/Neugutstrasse junction.

The new underpass secures the link between Neugutstrasse and Geerenstrasse and, in so doing, the Richti site under the existing SBB (Swiss National Railways) railway line. The cycle path and footpath pass underneath the SBB lines running between Wallisellen and Effretikon/Dübendorf. It allows a separation of car and pedestrian/cycle traffic on Neugutstrasse between the junctions with Breitestrasse and Hofstrasse.

Special Features of the Project
