‘My greengrocery couldn’t survive M6 road closures’
Casey said the period between spring and autumn was the shop's busiest time and would usually make up for losses over the winter period.
He said they "couldn't survive" a significant drop in business, it was "plain and simple".
Sarah Dunning, the chair of Westmorland Family which owns Tebay Services and Junction 38 Truck Stop, said the review marked an important reset in relationships and has reiterated her commitment to keeping Junction 38 fully open during the project.
Liberal Democrat MP for Westmorland and Lonsdale Tim Farron said campaigners needed to remain "engaged".
He said while it was "positive news" it was possible at the end of the review the closures could still be a "final option".
The spokesperson for National Highways 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."
