Fears over safety have led to the temporary closure of a section of dual carriageway on the A90 approach to Ellon.
Part of the inside lane on the Tipperty stretch leading to the roundabout is expected to remain shut until this weekend.
The left hand lane at the roundabout has always been for traffic heading onto South Road onlyCllr Richard Thomson Ellon and District
Ellon’s South Road is meantime closed to allow work to be carried out at the entrance to the new academy complex at Cromleybank.
But it has been claimed that drivers have been using the inside lane - designated for South Road traffic - on the approach to the roundabout to carry on northbound, which is single carriageway.
A spokeswoman for Aberdeen Roads said: “Following the closure of the B9005 to allow for works to continue on the Ellon Academy, Aberdeen Roads has liaised with the contractor working on the Academy, to introduce traffic management measures on the approach to the B9005 turn off.
“There traffic management measures involve the closure of lane one to avoid traffic merging on the roundabout.”
Welcoming the move, Ellon and District Councillor Richard Thomson said: “The left hand lane at the roundabout has always been for traffic heading onto South Road only.
“If people have been getting confused over the closure then that’s one thing, but if drivers have been deliberately using this inside lane to try and undertake the queue of traffic continuing northbound, then that’s not only selfish, it’s also potentially very dangerous to other road users.
“If cutting the A90 down to one lane temporarily while South Road is closed is seen as the best way to cut this sort of nonsense out and maintain safety then I’m all in favour.”
The closure is the latest in a series of roadworks in and around Ellon in recent weeks.
The South Road work is expected to be completed this weekend.
Ellon Academy Community Campus will open to pupils in August.
