Marshall Swalwell wants to expand Auchenlarie Holiday Park but has been told he must fork out £150,000 to make the entrance safer by adding a filter lane for traffic entering from the west – the scene of several crashes recently.
And since Transport Scotland have already forced him to pay £52,000 to close an entrance, Mr Swalwell feels another £150,000 to make further alterations is an unrealistic amount to ask him to find.
He said: "If we can't find the funding for this and we end up reducing our fleet, we may have to let people go.
"Improvements are urgently needed. Not wishing to be too dramatic, it seems someone will be killed before action is taken."
He added: "I totally agree with what Transport Scotland are proposing, I do – their plans make a lot of sense and I can see how everyone would benefit from them, given the recent spate of accidents on the road.
"But my problem is that I don't see why I should be expected to pay for it all, having already made changes to the road and paid for it upon their request. In my view, Transport Scotland are responsible for ensuring the road is safe.
"As our expenditure has caused a deterioration in safety then Transport Scotland should surely be responsible for funding the necessary improvements."
Mr Swalwell says without permission to expand, the business may have to reduce its letting fleet by 43 or the equivalent of 108 bedrooms if it were a hotel – a potential loss of 13,000 visitors to the area a year, plus the loss of at least seven jobs.
He added: "We feel very strongly that, despite Transport Scotland's assurances, the current road system now is inferior to the original."
Since taking over the park 23 years ago, Mr Swalwell and his family can recall just two shunts on the road, but since Transport Scotland had him close off the west entrance there have been four reported incidents in nine months – one involving a member of his staff being airlifted to hospital.
He said: "There have been more which haven't been reported – another one involving a staff member. There was never an issue before yet I was forced to close the entrance, which I did at my own cost.
"I want to add more pitches, but if I pay for these works to be done the cost of each pitch before I've even started on laying them will be £3,000."
MP Russell Brown
visited the park last month and agrees Mr Swalwell should not be made to meet further costs for road improvements.
He said: "I have written to the chief executive of Transport Scotland, David Middleton, to urge them to consider assisting with the funding of this work."
Transport Scotland's Ken Aitken said: "Given that any road alterations which are required as a consequence of development are always paid for by the developer ... Transport Scotland are not in a position to fund an improvement which is the result of the impact of a private development."
