One of the best ways of improving the roads for cycling (and others) is to repair potholes and resurface carriageways. There are several on line reporting tools for doing this I used to use fixmystreet.com, mainly because it has categories for other street based problems, but now I use Love Clean Streets via their app, or I use the councils’ own websites.
I do encourage you to report potholes via Love Clean Streets or council websites. B&D Council has not covered itself with glory in this regard. You need to keep monitoring. You may find as I have that they say repairs have been done when they haven’t in fact, or that they close reports for spurious reasons – one example was they said they couldn’t find the hole – this was despite it being pinpointed on their map and by means of its street address.
