Diolch, Llywydd. As you said, and when you cut the first sod on 17 January, you anticipated completion by autumn 2021. What contractual safeguards have you secured regarding that, and, given the concerns raised by some significant local businesses, when the first two initial preferred routes were announced, that there hadn't been a local business impact assessment, what dialogue have you had with them over potential mitigation measures to minimise any negative impact upon them?
