The two-week scheme requires full closures of the M6 junction 8 north and southbound exit slip roads, the M6 junction 9 southbound entry slip road and the M5 southbound between the M6 junction 8 and M5 junction 1.
As the scheme progresses, a second phase will require the M5 southbound to be closed between junctions 1 and 2, including the entry slip road at junction 1. The M6 southbound will also be closed at junction 10.
All closures take place on weeknights only, between 9.30pm and 5.30am.
Highways Agency Project Manager Purnima Kaul said:
Road users will benefit from this work as we are providing a better quality carriageway with fewer surface defects. During construction, we advise drivers to allow extra time for their journeys.
During the first phase of closures traffic will be diverted off the M6 at junction 7 and on to the A34, A4041 and A41 to join the M5 at junction 1.
When the M6 is closed at junction 10, traffic will diverted off the M6 southbound at junction 10 along the A454, A4148 and A34 and back to the M6, rejoining at junction 7.
During the second phase of closures traffic will be diverted off the M5 southbound at junction 1 and along the A4252, A457, A4034 and A4123 to rejoin the motorway at junction 2.
