A £600,000 programme of roadworks will take place on two sections of the A9 Perth to Inverness road.
Motorists could face delays with a convoy system and temporary traffic lights in place during the work, which will firstly take place at the northern end of the Ballinluig dual carriageway near Pitlochry.
This will be followed by work to a section of the road at Clunes Lodge, north of House of Bruar.
The roadworks are aimed at strengthening and resurfacing the road to make it more durable and resilient during the colder winter months.
Work will begin on Monday north of Ballinluig and will last up to three weeks.
A spokesperson for BEAR Scotland said: “The 1.1km long improvement at the northern end of dual carriageway near Pitlochry will be carried out between 7am and 7pm each day from Monday to Friday for up to three weeks, with no works programmed for the weekends.
“During the surfacing improvements, lane closures with temporary traffic lights and a 10mph convoy system will be in place for the safety of the workforce and members of the public.
“There will also be a short intermittent local diversion in place whilst works are in the immediate vicinity of the Pitlochry slip road. However, the slip road will always remain open outside of working hours.
“The convoy system will also not be required in the evenings and at weekends but a lane closure and 30mph speed limit will be in place to protect traffic. The southbound A9 will be unaffected during these works.”
Overnight work will then take place on the A9 at Clunes Lodge beginning Sunday, March 12, and is again set to last up to three weeks.
Eddie Ross, of BEAR Scotland, said: “The £600,000 investment from Transport Scotland will allow our teams to ensure the A9 continues to provide a safe and reliable route for motorists at these two locations.
“We have taken steps to minimise disruption as much as possible during these schemes, including scheduling the works to avoid working at weekends and ahead of the busy tourist season.
“Our teams will look to complete both schemes as quickly and safely as possible.”
