Drivers on the M6 could be facing delays from Monday night as contractors block off the northbound section in the first of 12 overnight closures.
Traffic will be diverted off the motorway at the Tickled Trout Hotel and through Preston to the Broughton roundabout as work to widen the pinch point between junctions 31 and 32 reaches a critical stage.
Highways Agency staff are advising motorists to follow the diversion signs, with queues likely even though the detour is being operated during the night.
The closure will be in place from 9pm to 6am tonight, Tuesday, Wednesday, Thursday and Saturday. On Friday it will shut down between 10pm to 6am.
Next week the carriageway will be blocked off on Tuesday, Wednesday and Thursday from 9pm-6am and Friday 10pm-6am. There will also be two further clossures on Wednesday and Thursday (March 11 and 12) from 9pm-6am.
The diversion will take northbound traffic up the A6 Brockholes Brow, right along the A5085 Blackpool Road and then up the A6 Garstang Road to rejoin the motorway via the M55 eastbound link road to the M6.
But on top of that the situation will become even more complex when the eastbound link from the M55 on to the M6 northbound carriageway also closes on Monday March 2 and again on Friday, Sunday and Monday (March 13/15/16) between 9pm and 6am for additional work. Drivers seeking to join the northbound M6 should leave the M55 at junction 1 and follow the A6 north up to junction 33 of the M6 at Galgate.
And the northbound M6 will also be closed from junction 32 on Sunday March 1, Tuesday March 10 and Saturday March 14 – between 9pm and 6am each night.
Drivers wishing to continue on the northbound M6 will be diverted west along the M55 to junction 1 at Broughton where they can join the eastbound M55 and the link road onto the northbound M6.
The £7m project is designed to widen the M6 northbound from two lanes to three between junctions 31 and 32 to alleviate hold-ups.
