Drivers are being warned to expect four days of delays as massive 27-tonne steel beams pass through Aberdeen in the next week.
A total of 28 20m-long beams will be delivered to Dyce between Saturday and Tuesday, where they will form a new bridge over the Aberdeen to Inverness railway line.
The new structure is part of the Aberdeen Western Peripheral Route/Balmedie to Tipperty road (AWPR/B-T), designed to improve travel in the city and throughout the region.
In October, the first bridge beams were installed at the new Tipperty junction which carried the A90 over the B9000 Newburgh to Pitmedden road.
The beams will be transported in 14 wide load vehicles, each carrying two beams.
For safety reasons, the trucks will be delivered between 9.30am and 3.30pm every day.
Their progress will begin on the A90, then the A956 and West Tullos Road, before they cross the River Dee and go down Riverside Drive.
The trucks are then going to move along Holburn Street, Anderson Drive and Inverurie Road, before finally arriving at Dyce Drive.
The beams will be stored at the observation area overlooking the runway at the north end of Dyce Drive before being transferred to the construction site.
The observation area will be closed to traffic from Saturday until Friday, January 15.
Keith Brown, cabinet secretary for infrastructure, said: “A great deal of planning has gone into ensuring two lanes of traffic are maintained on the A90 during peak periods as the junction is created.
An AWPR/B-T spokesperson said: “Beam deliveries are integral to the AWPR/B-T project, which will have 75 principal structures, two river crossings, one railway bridge and over 70 culverts.
“We are working closely with Police Scotland and the local authorities to minimise any disruption that these deliveries may bring.
“We would like to thank the north east community for its on-going support and patience during the construction of the AWPR/B-T.”
Dyce, Bucksburn and Danestone councillor Graeme Lawrence said the disruption would be “worth the wait”.
He added: “I’d advise people to be aware that they [the beams] will be coming through and leave extra time for their journey if need be.”
