This is a mistake, the tool recorded the position of my car where I made the note. I can not just stop the car and make notes, as there are also other people who drive in CERN.

The one way road is somewhere else!
IIRC it is Route Salam where it connects to Route Bakker.
At the bend there is the well known red sign with the white bar and a sub sign allows cyclists.

I will drive there and make a photo in the next days.
