The Scottish Government has been urged to improve safety at a slip road on the Aberdeen bypass “before it causes a fatality”.
North East MSPs Liam Kerr and Alexander Burnett are calling for action following a number of complaints about safety at the Kingswells south junction.
Among the issues raised is queues of traffic building up onto the A90.
There have been several crashes at the spot this year.
In one incident, a man was seriously hurt after his car rolled onto its side with his wife and son on board.
Concerns were expressed to Transport Scotland as part of a safety audit on the slip road, which said that drivers frustrated by delays at the stretch were displaying “unexpected driving behaviour and manoeuvres.”
Now Mr Kerr and Mr Burnett have written to Transport Secretary Michael Matheson to question why safety improvements have not yet been made.
Their letter states: “There are reports that vehicles are having to queue on to the dual carriageway to exit the slip road, meaning that other cars are travelling up behind them and/or passing at 70mph.
“We feel that this matter needs to be resolved with some sense of urgency – it simply cannot be that it is not taken seriously until after an accident happens.
“We share local concern this is a tragedy waiting to happen and hope you can agree this is extremely unsafe and worrying for those who use this road.
“We would be grateful if you would be able to provide an update as to when we can expect these solutions and the potential timeframe to resolve the issues at hand.”
A Transport Scotland spokeswoman said: “Safety is of paramount importance to us.
“We are working closely with Aberdeen City Council to identify measures to improve the performance of the Kingswells south roundabout junction.
“Once an approach is agreed, we will provide road users with an update on these plans.
“We continue to advise motorists to adjust their driving to align with road conditions and always to approach any junction with care.”
