A construction traffic management plan has been agreed with all relevant local authorities. This sets out the roads our vehicles can use for construction works.
You can find our upcoming traffic management plans and temporary closures below. Please note that these dates are indicative and may change at short notice.
We are working with our contractors to keep disruption to a minimum, and we will keep this webpage up to date with new information once confirmed. You can register your details with us here and we will let you know when more information becomes available. Thank you for your patience and understanding.
