A project to upgrade a motorway bridge which carries the M6 over Penny Lane near Haydock has started.
Contractors for Highways England need to close a two-mile stretch of the southbound carriageway overnight for four nights during February and March while essential work takes place to waterproof and resurface the bridge.
Work will take place in a number of phases over approximately six weeks.
To set out the traffic management and carry out the work safely, temporary overnight closures of the M6 southbound carriageway between junction 24 in Ashton-in-Makerfield and junction 23 at Newton-le-Willows.
The closures scheduled to take place as follows:
Friday, March 4, between 10pm and 6am
Sunday, March 6, between 10pm and 5am
Once the M6 carriageway re-opens, two lanes will be open with a 50mph speed limit in place.
Between the hours of 8pm and 5am on each Saturday and Sunday, the main carriageway will be reduced to one lane.
Further overnight lane closures will be required to complete the jointing and surfacing works
for an additional two weeks.
Mark Mosley, project manager at Highways England, said: “This is essential work which will ensure the bridges remain in good shape for many years to come, and should reduce the need for future resurfacing work.
“We need to close a two-mile stretch of the southbound carriageway overnight on Friday and Sunday nights during two weekends to set up and remove the traffic management cones and barriers.
“They’ll be a clearly-signed diversion in place when the motorway is closed, and we are carrying out the work at times when the motorway is at its quietest to keep the impact to a minimum.”
