Hard to believe that video that it is still not fully separated after Roosikrantsi. It is what it is then. Upon checking more of the videos regarding that segregated separate cycle and footh path, between Tõnismägi bus stop and Kaarli/Tõnismägi road cross, the cycle path again combines to Kaarli pst for just a bit. After Tõnismägi it separates again up until Roosikrantsi.
That small part is separated with curb but was not able to see if its high curb or some low curb.

Either way, the cycle path should be then starting from
Endla vehicle path or just after Kaarli/Tõnismägi path crossing due to that small piece of cycle path that is going back to Kaarli pst side right after Tõnismägi bus stop?
