Motorists across Tayside are being warned of delays as work on a £60 million windfarm progresses.
Lorries carrying wind turbine parts will be making their way from Inverness and Grangemouth to Clashindarroch Forest, near Huntly.
The site, on the edge of the Cairngorms National Park, is earmarked for 18 wind turbines, measuring 360ft.
Energy firm Vattenfall laid the first foundations for the development last month, and are now pushing on with their plans.
The first lorries began making the journey to the site on Monday and police are warning motorists they are likely to face similar delays over the next two months.
The blades will be transported from Inverness harbour via the A9 between the city and Perth and the A96 Inverness-Aberdeen road on Monday, Wednesday and Friday mornings from 9.30am.
They are expected to arrive in the Huntly area at about 1pm. Other components will make their way north from Grangemouth using the A90 Dundee to Aberdeen road and A96 going via the B9001 Inverurie to Meikle Wartle and the A920 Oldmeldrum to Culsalmond roads to avoid Inveramsay Bridge arriving at about 1.45pm.
It is expected the windfarm will start generating electricity later this year, with developers claiming it could eventually power more than 24,000 homes.
