M4: Repairs and Maintenance

Question

To ask the Secretary of State for Transport, whether her Department plans to review diversion routes for M4 closures to ensure that country lanes are not used.

Answer

For planned closures on the M4, National Highways will identify and review diversion routes in advance to ensure they are safe, suitable and appropriate for the surrounding road network, including for heavy goods vehicles.

National Highways will agree diversion routes with the relevant local highway authorities, ensure they are clearly signed in line with national standards and ensure they are monitored while in operation. Diversion routes are kept under review and may be amended where issues are identified.
