The Leeuwerikstraat is almost completely one-way.

From the intersection with the Kievitstraat, you're allowed to drive in front of house numbers 47 and 45. After that, there's a no-entry sign.
This sign can be seen on Google Streetview: https://maps.app.goo.gl/DxsUrGzEXjx5hCNj9

Coming into the Leeuwerikstraat from the "Scherpenzeelseweg", you's see the one-way sign, as well:

So, this street should be marked one-way, starting at the "Scherpenzeelseweg".

The "Nachtegaalstraat" is marked one-way in the wrong direction.
It is one-way, from the intersection with the "PutterStraat" and "Kievitstraat", towards the intersection with the "Sherpenzeelseweg"
