Motorists on Deeside are being warned to expect three months of delays while a new sewer is installed.
Stewart Milne Homes is currently building 45 homes at Crathes, which will treble the size of the village.
To service the development, a new sewer needs to be laid and traffic management measures will be in place from early January while the work is carried out.
Traffic will be controlled by either temporary lights or a convoy system, where possible, to minimise congestion during peak times.
The work, which is expected to take 12 weeks, will be carried out Monday to Saturday by contractors WM Donald.
Philip McKay, head of roads and landscape services for Aberdeenshire Council, said: “We apologise for any inconvenience caused to road users while this necessary work is being carried out by contractors working on behalf of the developer.”
Stewart Milne Homes applied for permission to build the homes last year, but the proposals were unanimously rejected by local councillors amid concerns that the size of the scheme would ruin the character of the area.
However, the Scottish Government overturned the decision on appeal and work began earlier this year.
The developer expects the first residents to move in during the first half of 2015.
