Air quality on Neath Road in Hafod in Swansea is amongst the worst in Wales, due to both its importance as the main road from the north-east into Swansea city centre, and its topography. I welcome the Morfa distributor road, which will reduce air pollution on Neath Road. Does the Cabinet Secretary agree that a bypass is not the solution to all problems of poor air quality, but, in some cases and certain circumstances where the road is a major road and the topography is such that nothing else can be done, that it can be?
