Question to the Department for Transport:

To ask the Secretary of State for Transport, what modelling has been undertaken on the potential impact of diverting traffic from the M6 onto local roads, including the A685, during the proposed closure of junction 38.

Current traffic management proposals for the M6 Lune Gorge project are being designed to keep traffic on the M6 motorway for the majority of the project. A contraflow system is planned on the M6 to provide a safe working area for construction, while maintaining sufficient lane capacity to avoid significant disruption to drivers.

There will need to be a limited number of full closures of the M6 overnight and at weekends. During these closures, traffic will be diverted onto the local road network using the A6, A591 and A590. This diversion route has been agreed with the relevant local highway authorities as the most suitable option.

National Highways’ current proposals for traffic management arrangements at Junction 38 would keep the junction partially open with traffic diverted via the M6 to the next junction and then back. National Highways is still considering options proposed by stakeholders, including temporary slip roads at junction 38 and other traffic mitigations.

National Highways does not intend to use the A685 as a diversion route. The decision to defer Lawtland House Bridge works, which the A685 runs over, was made to provide additional connectivity to the local community during the Lune Gorge project.
