Hi thanks for your report.
There was no closures on Rowans Rd today that I can see. I have looked it up and there is construction work going on and according to Kingston Council
“Works are expected to begin the week of 10 February 2020 and will be completed mid-year. There will be short term parking restrictions and at times full road closures will be in place”
It sounds like there are not permanent closures so I am loathed to close it for 20 weeks.
It sounds like you may have had trouble adding a closure via the app - did you click on the correct arrow which would then let you define the duration of the closure? You’ll know its been successful when you get the thank you message and 6 points.
