AT LEAST one business may be forced to close with five jobs lost to make way for the planned £27 million link road.
The firm, which asked not to be named, is among dozens of landowners and business owners between Wilson Way and Dolcoath Road who are being forced to sell plots to create the road linking Camborne, Pool and Redruth.
Cornwall Council was given powers to issue Compulsory Purchase Orders (CPO) last year after the Government approved the scheme expected to create up to 6,000 jobs.
Some traders feared the plan will badly affect their business, although others said they were "broadly content" with it.
Phil Dudley claimed the project would potentially drive his family car sales firm at Dudnance Lane out of business.
"I have space for 30 cars but they are putting it down to 12 because I am not allowed to use the space on the other side of the road anymore and the new entrance to my forecourt means I have less space on the sales yard.
"I might lose my business, which I have run for 25 years, because of this. We just want to carry on as it was because it is a good trading place. I am going to take it further."
Another business owner, who asked not to be named, said he was likely to cease trading by March 31. A spokesman said the forced land acquisition would not leave enough space to continue operating. "It is really demoralising and my staff are concerned about being made redundant."
Graham Stone, said the anticipated loss of about three metres of forecourt from GT Stone & Son at Dudnance Lane should not seriously affect his lorry park.
Meanwhile manager Graham Linney, of Philip Whear Windows factory and showroom at Wilson Way, said: "They will create a new entrance at the highway and modify the existing one so we are broadly content with the proposal."
Richford Fire and Flood, also at Dudnance Lane, will lose part of its access, forecourt and car park, but manager Mike Cooper said: "There's a level of disruption that comes with it but we are supportive of the economic development of the area.
"If the council works with local businesses to get the detail right then hopefully it will bring real benefits."
A spokesman for Cornwall Council confirmed compensation negotiations were under way with a number of owners but can take a long time and did not have to be completed before land entry was taken under a CPO: "The whole point of a CPO is that it gives right of entry even if negotiations are not completed. The estimated costs have been included in the scheme estimate of £27 million."
Statutory provisions will ensure landowners were not financially disadvantaged in negotiations over the loss of their land.
