Concerns about the £1m-plus losses suffered by businesses along the route of the £3.6m A38 roadworks through the Glynn Valley will be raised with Highways England, the area’s MP has vowed.

The Cornish Times last week revealed that Trago Mills had lost a ‘seven-figure sum’ in trade after the scheme started in January and had been forced to make job cuts.

The Halfway House pub at Twowatersfoot said it had been forced to close, and Carnglaze Caverns, near St Neot, said trade had fallen by 50 per cent.

Trago chairman Bruce Robertson held talks with South East Cornwall Conservative MP Sheryll Murray.

Mrs Murray told the Cornish Times: ‘He made me very aware that despite the fact that Highways England had consultations, the scheme has affected their businesses a lot more than was thought.

‘He is going to supply me with more figures and I am going to take it forward to Highways England.

‘I think what businesses feel, and I quite agree, is what studies did Highways England do to look at and assess the economic effects it was going to have on businesses?’

The stabilisation and safety works scheme is due to finish weeks later than scheduled in May.

Mrs Murray said she encouraged any businesses affected to contact her so she could include their concerns in her meeting with Highways England – though she did not know what effect the shock snap General Election announcement might have.
