Motorists have been warned of a closure on the M6 near Preston.
The southbound M6 at the Broughton Interchange will be closed for three nights to repair the bridge linking the M6 and the M55.
The repairs to tackle collision damage include barrier and structural repairs on the link road bridge and are due to start on Sunday.
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.”
The link road will be closed from 8pm on Sunday night until 5am on Monday morning for barriers and cones to be laid out.
The repairs will then begin on Monday for up to 13 nights – with work taking place between 10pm and 6am each night. Most of the nights involve the closure of two lanes but three of the nights will involve a complete closure of the southbound carriageway under the bridge as concrete repairs are made.
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.
Quick-drying mortar will used during the bridge barrier repairs to complete the scheme and the overnight work as quickly as possible and minimise disruption to motorway users.
A second phase of work to complete repairs to the link road barriers is due to take place in July.
