The firm was named on a final shortlist of two in March alongside Balfour Beatty Civil Engineering Ltd, which pulled out of the running later in the year.

The contract involves the construction of around 500m of new dual carriageway connecting the A90 North Anderson Drive and the A96 Auchmill Road, alleviating some of the bottlenecks at the notorious roundabout.

The project will also enable new pedestrian and cycling routes through the local area.

Ross Grant, Aberdeen City Council’s transport spokesman, said: “After repeated delays to the commencement of works at the Haudagain, it has to be welcome news that a contractor has been appointed.”

Work, which will begin once the last section of the AWPR is completed, is expected to be completed in 2021.
