The Highways Agency is carrying out wear and tear repairs to the bridge structures which support the junction roundabout above the motorway carriageway.
All the repairs, which will be completed ahead of the Christmas break, will be done overnight.
Highways Agency project manager Mark Mosley said:
This is routine work to repair the reinforced concrete bridge piers and keep this busy junction in good shape. To minimise inconvenience to drivers we are restricting work to overnight periods but for safety reasons drivers travelling through the junction under the roundabout bridges will find a temporary 50mph speed limit and narrowed lanes.
Drivers are being advised that setting out traffic management for the work will require four short overnight closures of the motorway between midnight and 4am on each of the nights involved.
Two overnight closures – with the motorway closed in both directions between junction 21A at and junction 23 at Newton-le-Willows – will take place on Wednesday night (5 November) and Thursday night (6 November). A clearly-signed diversion will be in place between junctions 21A and 23 using the M62, A49 Winwick Road, A579 Winwick Lane and A580 East Lancs Road. Two further overnight closures to remove the traffic management will take place later this year at the end of the project.
