I think we all know something has to be done but what is surely the question.
London Road is the only road out of the middle of town going towards Whitfield so the slightest problem causes hold-ups, similar to Barton road and Maison Dieu coming into town.
The article mentions "vehicles regularly cause congestion problems" in Pencester Road, which is not something I have noticed, in fact it always seems to be one of the better free flowing roads.
