From tonight (Monday 13 October), and for the following three consecutive nights, there will be overnight closures between junctions 10A and 11 of the northbound carriageway and junctions 13 to 12 of the southbound carriageway, while work is carried out to install overhead signs.
The northbound closures will take place from 10pm to 6am between junctions 10A Walsall to 11 Cheslyn Hay on Monday 13, Tuesday 14 and Wednesday 15 October.
The southbound closures will take place from 10pm to 6am between junctions 13 at Acton Trussell to 12 Cannock on Wednesday 15 and Thursday 16 October.
Highways Agency project manager David Cooke said:
Construction of this important scheme, which represents £102m of investment, is progressing well. We are now ready to install equipment on overhead gantries but to do this as safely and efficiently as possible, we need to close carriageways overnight.
We advise motorists to allow at least an extra 45 minutes for their journeys when travelling along this section of the road.
Once the scheme is completed, it will help reduce congestion and improve journey times.
During the northbound closures, traffic will be diverted off the M6 at junction 10A along the M54 westbound to junction 2, then northbound on A449 to the intersection with A5 at Gailey, then following the A5 eastbound to M6 junction 12 and rejoin motorway.
When the southbound carriageway is closed, traffic will be directed off the M6 at junction 13 along the A449, then the A5 at Gailey to rejoin the M6 at junction 12.
On Friday 17 and Saturday 18 October, the M6 southbound carriageway between junctions 13 and 12 will have two lanes closed, and the southbound exit slip road at junction 12 will be closed, from 10pm to 8am. On Sunday 19 October the same closures will apply from 10pm to 5.30am.
