Temporary overnight lane closures on the M6 motorway between junction 4 and 4a – near Chelmsley Wood

What we are doing

The M6 South Viaduct will carry the new high-speed railway over the M6 motorway and adjoining slip road, near Birmingham Business Park, Birmingham Airport and the NEC in Solihull. We successfully completed the first phase of the M6 South Viaduct launch over the slip-road on 8 June 2025.

Before progressing the second launch of the viaduct across the M6 motorway in September 2025, we need to carry out a series of surveys on the existing lighting columns located within the central reservation. To ensure the safety of our workforce while undertaking these activities, the following traffic management measures will be put in place:

M6 motorway northbound and southbound carriageway overnight lane 2 and 3 closures between junctions 4 and 4a

Each night from 9pm to 6am on Tuesday 26 August, Wednesday 27 August 2025

Details of the next phase of works for the M6 South Viaduct structure, scheduled to commence in Autumn 2025, will be communicated once confirmed.
