Temporary traffic lights are expected to be in place on a busy North-east road for four weeks as part of AWPR works.
The temporary measure, which is due to be effective at the junction of the A93 North Deeside Road and B979 Milltimber Brae from Saturday, is due to construction work to install permanent traffic lights at the site.
Drivers are being warned of potential delays from 7am Saturday.
A road closure of the B979 at the junction with the A93 will also be required mid-November to allow surfacing works to be completed prior to the signals becoming operational.
A Transport Scotland spokesman said: “Temporary traffic signals will be in use to enable the contractor to continue construction works safely.”
