Drivers are facing disruption during roadworks on the A9 north of Dunkeld until early August.
A resurfacing project is taking place between Dalguise and Ballinluig.
The roadworks got under way this week and will run until the first week of August.
The £530,000 project is being carried out by Bear Scotland.
It comes as drivers are already facing delays on the A9 at Luncarty, just north of Perth, with a contraflow also in place until early August.
