Last field trip in Zurich with students in urban planning at Uni Lausanne
Zurich is a fascinating city (e.g. the financial capital of Switzerland has 25% of its housing stock which is non profit)
This year I noticed for the first time the cyclists on the building of the urban planning department!

Motorways are cumbersome. Zurich shows 4 ways of dealing with them...
😱 Finding space over a river (that's so 60s...)
😮💨 Stoping building them abruptly (better late than never?)
😀 Covering them with a park (Ueberlandpark)
😀 Turning them into a cycling tunnel
