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. The viaduct will be constructed using an incremental launch method. We successfully completed phase one of the M6 South viaduct launch in June 2025, launching the first section of viaduct over the M6 J4 off-slip.
Before we progress with phase two in September 2025, we will carry out essential lighting column works in the M6 central reservation. To ensure the safety of our workforce the following traffic management will be installed.
Overnight lane closures northbound and southbound between J4 and J4A
- Each night from 9pm Monday 22 September to 6am Friday 26 September 2025
Following these closures, phase two of the M6 South viaduct works will begin, continuing the ‘East Deck’ launch over the M6 carriageways and the M42 J7a link. To do this safely, the M6 will close in both directions between J4 and J4a, including M42 J7a to M6 southbound.
Full weekend closure of M6 carriageways between J4 and J4A including M42 J7A link to M6 southbound
- From 3am Saturday 27 September to 10pm Sunday 28 September 2025
