When I rent my apartment, I was told that it will last until probably 2020 Spring because the road will get widened and the building will be eradicated.

However, I haven't received further information any more. Do you know where I can search/ask? My housing agency didn't answer my email.

Thanks a lot!

Crazy I know... but maybe call them?

The planning dept of the city hall should be able to inform you about any road widening projects, and which buildings are affected. For the more major projects you can even download plans online, although the website can be a bit tricky to navigate IMHO.

Why not start off by making an appointment with somebody from the planning dept? This is public information and you have a right to know, even if it's not your land.

Often projects like this run late because of objections, appeals or difficulties acquiring land. Maybe your landlord is holding off informing you until he knows facts rather than just intentions.

Ask the city when they plan to start the works (or see if such can be found on their website)

Thank you all for your suggestions!

I was looking in the website from Stadt Zurich, and found some street/tunnel project on Ueberlandstrasse but it seems far away from my apartment, there's no regional map on affected buildings. Maybe I could use the contact form on their website...
