The trial of the white lines and sight lines in the centre of the park is over, and now you can say what you think in the latest phase of the consultation here:

The Council Officers said to use that they had no specific plans to extend the white lines over the whole of the route in the park (at present they are just on the approaches to the centre). But if you have views about that possibility we suggest you air them.
There is also a bit of intro which you can check it out here: Roseburn_Park_Trial_Consultation_Summary_Sheet.
