You've answered my supplementary question already, Minister. Clearly, this question is as well worn as that road surface on the A40, which I raise frequently. As you've just said, residents living in the Bryn and neighbouring communities close to the A40 dual carriageway do put up with daily noise pollution because of the ageing concrete road surface of that stretch of road, which needs to be replaced at some point with whisper tarmac. I know your officials have been working on noise mitigation proposals, including acoustic fencing—you've already mentioned that, so I'd be grateful if you could give us a timescale for that. Also, something that came up at a recent residents meeting—has any consideration been given to the possibility of a reduction in the speed limit for at least a stretch of that road? Because in other areas where speed limits have been reduced, maybe to 50 mph, that does produce a lower level of noise pollution. It may be one easy, quick solution to actually dealing with some of that noise pollution.
