Motorists are facing disruption next week when a roundabout is removed on a busy north-east road close to Aberdeen Airport.
Transport Scotland said the temporary signals will be operating at the A96 Aberdeen to Inverness Road/Dyce Drive Junction on Monday.
The move forms part of the multi-million-pound Aberdeen Western Peripheral Route/Balmeddie to Tipperty project which is expected to be completed in late 2017.
Traffic cones and roadworks have already been causing recent lengthy queues from the A96 to the airport.
It will cover 36 miles around Aberdeen, and will have 13 miles of new slip roads and two river crossings.
It is predicted that staff will have undertaken 1.7million hours of manual labour by the time the project is finished next year.
Transport Scotland said that temporary lights would allow the contractor to remove the roundabout and lead to the installation of permanent traffic signals.
An AWPR/B-T spokesperson added: “Drivers should take note of this change in priorities at this location.
“As with any change in road layout, we would recommend that all drivers using this route should apply more caution than usual.”
The Craibstone and Dyce Junctions are on schedule to open to traffic in Autumn 2016.
Last month, motorists were warned to expect delays while 20 massive beams were transported through the city.
The structures were transported one day at a time and will form part of the bridge over the A96 trunk road.
It was also decided last month that speed cameras would be installed on the A90 Aberdeen-Fraserburgh road between Blackdog and Balmedie, as part of the bypass works.
Temporary speed restrictions have been put in pace across the nort-east as work on the £745million AWPR is carried out, but countless motorists have ignored the 50mph speed limit on the A90.
The 50mph limit was brought in in January.
Police said they had been receiving daily calls about motorists failing to reduce their speed and have stepped up patrols, while contractor Aberdeen Roads repeated pleas for drivers to slow down.
