B&D council don't know what they've done

On 15 August I asked B&D council for a list of all roads in the borough down which one cannot cycle in either / both directions fully. On 3 November I got this answer which can be reduced to "we don't know":

"We do not have a register classifying roads in this way, however with very few exceptions almost all roads in the Borough have provision for cycling in both directions and where a road or part of a road does not make this provision, it is our understanding that alternative routes for cyclists are available very nearby. You have been informed previously of the Council’s commitment and support for cyclists and I can inform you that [names of 2 officers] continue to be available to work with you for the benefit of cyclists and cycling as a whole."

Very few exceptions, eh? Please let me know the names of roads in postal Dagenham and Chadwell Heath that habe any kind of restriction on cycling. I wil try to compose my own list. I know Barking well enough to cover it myself, I think, but don't let me stop you!
