Beams have been installed for a bridge to carry the under-construction Aberdeen bypass over a local road.
Timelapse footage shows the 23 precast beams – each weighing 20t and measuring 33m in length – being lifted into place.
It is part of the mammoth project to create 58km of new road around the northern Scottish city.
Cabinet secretary for infrastructure, investment and cities Keith Brown hailed the beam lift.
“This represents a significant milestone and shows that works are progressing well on what is the longest roads construction project currently underway in the UK,” he said.
“The beam lift at Tipperty is the first of almost 80 similar lifts which will be undertaken across the project over the course of the next couple of years with the pace of construction evident for all to see and the Balmedie-Tipperty section of the project due to open to road users in spring 2017.”
A joint venture of Balfour Beatty, Morrison Construction and Carillion is delivering the overall Aberdeen Western Peripheral Route / Balmedie-Tipperty project, which is scheduled to complete in late 2017.
