The Highways Agency will be carrying out overnight resurfacing work on the M42 near Solihull from 24 April, lasting five weeks.
The work will affect a two-mile stretch of the northbound carriageway between junctions 4 and 5 and the northbound entry slip road at junction 5 of the M42.
Although most of the scheme is scheduled to be carried using just lane closures and reduced speed limits, it may be necessary on occasion to close the whole carriageway to ensure the safety of the workforce in the road.
When the carriageway is closed, northbound traffic will be diverted via junction 4 of the M42, then the A34, B4025, B4102, B4025, A41 southbound and back to junction 5 of the M42. Southbound traffic will take the same diversion, but in reverse.
The northbound entry slip road at junction 4 and the junction 5 entry slip roads will be closed at various times.
When the northbound entry slip road at junction 4 is closed, traffic will be diverted south on M42 to junction 3 and then back north on M42. When the entry slip road at junction 5 is closed, traffic will be diverted south on M42 to junction 4 and then back north on the M42.
All work will be carried out from 8pm to 6am Sunday to Thursday, 8pm to 8am on Friday/Saturday and 8pm to 9am on Saturday/Sunday.
Highways Agency Project Manager Purnima Kaul said:
This work will improve the quality of the journey for road users by providing a smoother road surface.
To carry out this work we will need to close either lanes or the complete carriageway, but total closures will only be used if necessary in order to minimise disruption.
