The A90 between Stonehaven and Blackdog will become the A92 on Monday as works to update trunk road signage begins.
The change to the road designation forms part of the AWPR works between Balmedie and Tipperty.
Work will continue until Friday September 7 and will involve amending the existing A90 signage, by changing it to the A92.
This will include locations in Aberdeen City, including Charleston, Bridge of Dee, Anderson Drive, The Parkway, and Ellon Road.
Traffic management, such as lane closures, will be implemented overnight when necessary on the new A92 to enable the works to be carried out safely.
Some works, which do not require traffic management, will be undertaken during the day, but not during busy travelling periods.
No delays are expected as a result of these works.
Douglas Laird from Transport Scotland said: “This change to road designation is taking place now to give road users time to become accustomed to the new A92 road designation and signage in advance of the AWPR opening to traffic and becoming the new A90.
“These necessary works are expected to be undertaken over five days, with BEAR Scotland amending 125 trunk road signs.
“We would like to ask road users to observe all traffic management and to drive with extra caution while these works are underway to ensure their own safety, the safety of road workers, who will be working on or near to the main carriageway, and other road users.
“We would also like to encourage road users to drive more carefully than usual as they become accustomed to the changes in road designation.”
Police Scotland’s Road Policing Inspector Steve Manson added: “It is important for emergency services to respond quickly to incidents on the road network and to do this we need as much information as possible.
“By changing the A90 between Blackdog and Stonehaven to the A92 now, road users should become accustomed to the change in advance of the new road opening, however, our police control room operators are aware that people may forget, particularly if they are upset or under stress, and will do all they can to assist callers identify where they are.”
