I thank the First Minister for that reply. I'm sure he'd agree with me that upgrades are very welcome, but that they can sometimes cause disruption and economic costs, and it's important, therefore, that they should be completed as quickly as possible. At the moment, there's a resignalling project on the A477 to Pembroke Dock at its junction with the A4139. This is designated as a major European network road. It is, of course, the main route to the Irish ferry at Pembroke Dock and also the main route from Pembroke to the Cleddau bridge. Given that this is due to last for 17 weeks—that's nearly a third of the year—would it not be advisable in projects of this kind that they should be conducted not just in normal working hours but also at night or over weekends in order to reduce the economic dislocation that they will inevitably cause?
