There is a road closure near me which is not currently shown on Waze and Waze therefore keeps trying to route through this closure. I know it is there so why am I not able to simply mark a road as closed anywhere (ie not just when I am on a route)? Otherwise people will keep being routed towards a closure and the last thing they are thinking of when they are having to turn around and go a different way is to inform Waze about the closure. Seems such a simple fix and if you are worried about it being abused by people who would inform of closed roads as a joke, it could be verified by two or more users so that you know it is genuine.
