Diversions will be via Junction 32 Pic: Google
Motorists heading back on the M6 late on Sunday night will not be able to join the motorway southbound at Preston.
A bridge which carries the link road from Junction 32 at Broughton is being repaired by Highways England.
The link road is being closed from 8pm on Sunday (12 June) until 5am on Monday (13 June) for barriers and cones being laid out.
Repairs then begin on Monday for up to 13 nights, with work taking place between 10pm and 6am each night. Most nights will see two lanes shut, but three nights will see a complete closure of the soutbound carriageway under the bridge.
On those nights drivers will need to use the westbound then eastbound M55, via junction 1 of the motorway with the A6 at Broughton, to rejoin the southbound M6.
Highways England project manager Mark Mosley said: “The bridge was damaged during a collision and these repairs are vital in ensuring the link road, and M6 under it, remain safe for motorway users including people needing to use the hard shoulder in an emergency.
“This work will allow us to remove the existing temporary hard shoulder and 50mph restrictions on the bridge. We would like to thank drivers for their patience while the repairs take place.”
A second phase of work to complete repairs to the link road barriers is due to take place in July.
