Important reconstruction work will get under way later this month on 19th century Rob Roy Bridge in Peterculter.
Work to safeguard the structural stability of the historic landmark will cost £530,000 and is due to last for more than six months.
It involves the demolition of the reinforced concrete section of the bridge, which will be rebuilt to modern standards.
During the entire contract traffic lights will be in operation.
There will also be occasional full road closures - which will be limited to weekends.
The signed diversion route will be via the B9077 South Deeside Road. The work will start on Monday, June 27, and last for 26 weeks.
