Officers at Aberdeen City Council have warned of bottlenecks between the Aberdeen Western Peripheral Route (AWPR) and the north-east’s road network.
But Ross Thomson MSP said he has been told by Transport Scotland that any changes to the AWPR project would need to wait until construction has finished because the road is being built to plans that have already gone through the public consultation process.
Mr Thomson said: “I support what Marie Boulton is trying to achieve, she has received the same advice that I have from road officials in the council who already know of a number of junctions where there are going to be potential issues, where changes may have to be made.
“But the ridiculous thing is they cannot be made because the AWPR has already gone through the public hearing process, or so we keep being told by Transport Scotland.
“It’s really frustrating, because it seems we can’t actually address these issues until after the AWPR is built and we would then have to go back and make these changes – at an additional, most likely expensive, cost.
“Let’s not rule it out – this cost could go into the millions depending on what needs to be done.
“Transport Scotland should do the common sense thing and rectify these problems before it’s too late.
“I don’t think the people of Aberdeen and Aberdeenshire should be the ones to pick up the tab.”
A Transport Scotland spokeswoman said:
“As is the case with any major roads project, such as AWPR/B-T, traffic modelling is undertaken during the project development to inform the junction designs.
“Once the new roads and junctions are open to traffic, there is a period of post completion monitoring and evaluation.
“The information produced will then show the actual operation of the completed roads compared to the earlier forecasts.
“The responsibility for undertaking any future work on these roads and junctions depends on the specifics of each particular location.”
