The construction of a temporary bridge over a busy north-east road is shown in a fascinating new time-lapse video.
Transport Scotland released the recording of workers creating a new flyover of the A944 Kingswells to Westhill route.
Another temporary bridge is due to be built over the A96 Aberdeen to Inverness road near the Granite City’s airport at Dyce within the next few weeks.
The bridges will be used by workers and vehicles so they do not add to the congestion currently being experienced on north-east roads.
Almost 400 diversions are planned during work on the £745million project, which is due to be completed by winter 2017.
Work on the A93 at Milltimber, which started in April this year, is set to continue for another year-and-a-half to build a key stretch of the bypass.
The roadworks in the area will continue to run at weekends and off-peak times, and a range of traffic-slowing measures are to be in place.
Explosives are also being used in the Charleston area over the next eight weeks and to enable construction teams to remove rock and lower the ground to the level of the new Aberdeen Western Peripheral Route (AWPR).
Rock and earth excavated during the works will be reused for embankments and other purposes along the length of the 36-mile AWPR and new Balmedie to Tipperty dual carriageway.
In total, about 353 million cubic feet of earthworks and seven tonnes of hard rock will be extracted, transported and reused.
A Transport Scotland spokesman said: “The Aberdeen Western Peripheral Route continues to progress and commuters on the busy A944 from Kingswells to Westhill will have noticed the new temporary bridge that has been built to give AWPR construction workers uninterrupted access to the site.
“Another temporary bridge is due to be installed on the A96 near Aberdeen International Airport within the next few weeks.”
