Economy minister Keith Brown will be grilled on the progress of the AWPR later today.
The £750million Aberdeen Western Peripheral Route is nearing completion but concerns have been sparked following last week’s collapse of Carillion, one of three firms involved in constructing the road.
Fresh fears were also raised after an incorrect deadline of “winter 2018” was published in a Scottish Government report, which will be discussed at Holyrood’s rural economy and connectivity committee.
Transport Scotland has insisted it is nothing more than an administrative error but the Scottish Tories have said it highlights the uncertainty over the completion date.
North-east MSP Peter Chapman said: “I have asked repeatedly for assurances that the AWPR is moving on time and on budget, and have always been told that is the case.
“The cabinet secretary said earlier this month it would be completed in just ‘a few months’, and stood up in the chamber last week and said the collapse of Carillion would not derail the scheme.
“Yet, here we are just days later and, according to the committee papers, the date appears to have shifted by up to nine months.
“People in the north-east have been waiting for this road to be built for decades – and they have put up with considerable disruption over recent years while construction has taken place.
“We need clarity on when this project will be completed, as it appears increasingly unlikely that it will happen on the original schedule.”
A spokesman for Transport Scotland said: “We do not recognise the dates outlined in these papers and suspect that they contain a typographical error. We are currently working with ARL to understand the impact of the Carillion announcement on the project but there is absolutely no suggestion that the project will be delayed until winter 2018.”
