The Aberdeen bypass will open in autumn this year. Transport Scotland announced the revised date after previous opening dates slipped.
The £745 million AWPR project was originally to be completed by Spring 2017 but that was pushed back to Spring this year before the most recent delay.
The Economy Secretary Keith Brown has said: “While this revision to the opening date is very disappointing to the people of the North-East, we have to accept the expert advice of our contractors on the ground who are delivering this significant project.”
The Aberdeen bypass has had a long and difficult journey towards completion. The first proposal of a new bypass for Aberdeen was in 1952.
A public local enquiry was held in 2008-9. Following this, the current project was given the green light in 2009
It was delayed by legal action from campaigners which eventually ended in the Supreme Court in 2012.
The winning bidder for the project was announced in December 2014 as Aberdeen Roads Limited (Balfour Beatty Investments Ltd, Carillion Private Finance (Transport) Ltd, and Galliford Try Investments Ltd), who will construct the road, and operate/maintain it for a period of 30 years,
Construction proper began in February 2015.
The bypass is intended to reduce congestion during rush hour in Aberdeen, particularly around Anderson Drive, King Street, and Union Street. It will also mean heavy goods vehicles that do not need to enter the city will be reduced.
It has also been argued the road will help the local economy, particularly in the case of easing congestion at the Haudagain roundabout, which the Institute of Directors Scotland has in the past said costs the local economy between £15 and £30 million every year.
Official estimates of the cost were originally between £295 and £395 million. Transport Scotland gave the cost at £745 million in 2012 prices.
Cost overruns on the project contributed to the collapse in January 2018 of Carillion. That, as well as weather conditions, have contributed to the delays.
