National Highways has released the latest dates for overnight M6 closures as it works to complete the Warrington to Wigan upgrade.

The work involves adding extra emergency areas, new technology and a lane in each direction to the motorway between junctions 21a and junction 26. 

Plus resurfacing all four lanes of the carriageway across sections of the route between Croft and Orrell interchanges is being carried out. 

Due to the size of the equipment required for the resurfacing there will be a series of 9pm to 6am overnight carriageway closures over the next three weeks:

  • M6 southbound junctions 22 to 21a – overnight closure on Tuesday, June 18 
  • M6 northbound junctions 22 to 23 – overnight closures  on June 18, 20, 24 and 26 
  • M6 southbound junctions 23 to 22 – overnight closures on June 27 
  • M6 northbound junctions 23 to 26 – overnight closure on June 27 and 28 
  • M6 southbound junctions 26 to 23 – overnight closures on June 19, 20, 21, 24, 25 and 26 

The precise dates and times of the work may be subject to change due to weather conditions or unforeseen circumstances. 

Clearly-signed diversions will be in place overnight when a carriageway is closed.

Some 30 miles of the extra resurfacing work has been completed – more than half planned. 

Most of 52 new overhead gantry-based advanced motorway indicator signs – needed to display red X’s and variable speed limits - have also been fitted on the new motorway gantries and tested. 

Almost all of 43 standalone message signs in the motorway verge which will be used to give incident and other information in text or pictograms have also been installed and tested. 

All of the upgrade’s 22 emergency areas will be completed in July.
