Letting Berlin breathe again. The test site is open for you.
What Is the Radbahn?
The concept of the Radbahn follows the approach of an urban development with bicycle infrastructure under and along the largely forgotten space of the listed elevated viaduct of Berlin's subway line 1.
Why "Letting Berlin Breathe Again"?
The Radbahn creates an urban open space. As a public space, it offers a place to take a breath in the hustle and bustle of the city. Here, people have the chance to enjoy riding their bikes, take a walk or a rest and playfully engage with urban space. Along the Radbahn, people will feel a sense of deceleration and get through the city with joy.
Results of the test site survey
1200 people took part in our test site survey, thank you very much! You can also read the full evaluation report in German here.
Have fun on the test site! You can continue to give us your feedback via our mailbox on the "Interaction Island" under the viaduct.
What's New?
We have actively tested and evaluated the test site until 15 june 2024. Of course, you can continue to experience the newly designed space.
We are taking a short summer break and are working on our evaluation and the final report.
The Test site has been build. What is next?
On April 25, 2024 we have activated the space under the viaduct and now you can experience it in a new way. Unfortunately, we cannot yet make a binding statement regarding the completion of the entire route, which will run from the Oberbaumbrücke in Kreuzburg to Bahnhof Zoo in Charlottenburg. The realization depends on planning and approval phases in the area of traffic and urban planning as well as on political will and can take a very long time.

What Is a Reallabor?
A Reallabor or ‘real-world lab’ describes a research method that involves practical tests of new, innovative ideas in public spaces.
Who's behind the Radbahn idea?
The Radbahn project is the first of many projects brought to life by the non-profit organization paper planes e.V. The purpose of this organization is to research social and technological ideas that will lead to urban spaces which are more environmentally and human friendly and thus more livable.
What's the Radbahn book about?
In 2017 our book was published. We developed first recommendations on how the Radbahn can be implemented and gave answers to questions on the technicalities of traffic planning. Ever since, the Radbahn was no longer utopia but on the way to concrete planning.
