Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps National Highways is taking to ensure the provision of timely and accurate physical diversion signage during planned and unplanned road closures.

National Highways follows the standards GG903 and GG907 outlined in the Design Manual for Roads and Bridges (DMRB) for diversion routes for unplanned events and planned works and activities.

These standards require NH to coordinate with customers and local traffic authorities and to conduct Customer Audits and annual engagements. National Highways monitor diversion routes for unplanned events through the National Highways operational reporting team.
