I reported them weeks ago. Highways will deal with anything fast if you can justify calling them a tripping hazard. But a hole in a drain big enough to throw you off your bike in the middle of the Wightman - bahn doesn't count unless it's going to devalue your stupid car.
Someone has moved the stones onto the pavement, but it seems a slow process. I'm not impressed either, it took weeks to get them to put a cover on this hole in Mattison which a small child could have fitted in!
