The fork between the Ris skolevei and the northern tip of Borgenveien is currently undergoing a major reconstruction: https://www.oslo.kommune.no/slik-bygger-vi-oslo/borgenveien/

The new pattern is by now mostly in place. There is a roundabout between Plantasjen and Borgenveien 54.

The parking lot "P Risallen, Vindern nord" has a new access next to Ris skolevei 2. There is no direct access (for cars) from the roundabout to the parking lot or Borgenveien 56 or 66. Only bikes have direct access along Borgenveien's original route.
