There are so many cars speeding down the Cambridge Street garages access road at the back of John Street and using it as a cut-through. Some cars I'm sure go up to 40mph when ragging it down such as short road. This is too fast, as sometimes there are children playing, and animals venturing out the back of people's gardens. I don't normally like speed humps, but I think one is required here, half way down the alley that spans across to the garages. 10 mph is enough for people who need to use this road properly (i.e. people who live in the houses and people who have a garage). Who should I write to, in order to ask for one?
