Works at Lune Gorge on the M6 are set to begin next spring and expected to run until summer 2031.
The scheme, which would take place between J38 for Tebay and J37 for Kendal, will see the updating of bridges which were built in the late 1960s, which National Highways say are ‘near the end of their lifespan’.
The public body added the work is ‘essential to keep drivers safe’.
But the plans have attracted criticism, with detractors citing the impact on residents, businesses which are based on or use the route, farmers and the wider tourism sector.
Now, National Highways has announced it will be conducting a full review on ‘how the project will be delivered’, followed by a public consultation.
A spokesperson added: “We recognise the importance of working with local communities and businesses to explore opportunities that could help reduce disruption while construction work takes place.”
MP for Westmorland and Lonsdale, Tim Farron, has previously voiced concern about the scheme, handing over a petition to Downing Street for Junction 38 to be kept fully open.
He said he ‘warmly welcomed’ the news that the works will be reviewed.
Mr Farron added: “This is a vitally important project but I have had significant concerns about the impact that the partial closure of Junction 38 would have on residents, businesses, farmers, and Cumbria’s tourism sector.
“I have been working with the local community over the past 12 months to make the case for National Highways to look again and I’m delighted that they have listened and have promised to look at every option at the table, including a commitment to a proper public consultation.
“I want also to say how proud I am of the local community, and how grateful I am to them, for campaigning so hard – it is an utter privilege to stand alongside them.”
