A9 motorists can expect two weeks of delays as road repairs begin in Highland Perthshire.
Lane closures, convoy systems and traffic lights will all be introduced as carriageway strengthening takes place.
The improvements will be made to a section of the A9 between Pitlochry and Bruar and begin on Monday February 6.
Described as “essential” by BEAR Scotland, they involve reconstructing a 20 metre section of the carriageway to the south of Bruar.
Transport bosses say delays are inevitable but that the £20,000 works are required to ensure the road remains safe.
The repairs will be carried out between 7am and 7pm each day and the A9 will remain open throughout that time.
Traffic management measures will require to be put in place, with a 10mph convoy system operating during the day time to “ensure the safety of road workers as well as motorists”.
The convoy system will be removed outside working hours, though temporary traffic lights will remain in place overnight as traffic will be running next to an open excavation.
BEAR Scotland’s Eddie Ross said: “These essential works will repair and strengthen a section of the ground beneath the road surface and re-align the carriageway to smooth out a dip in the road to ensure it remains in a safe working condition.
“The convoy system is in place for the protection of our teams as well as for motorists, and we urge motorists to follow any traffic management signs in place for their safety.
“We thank motorists for their patience in advance and would also encourage them to plan ahead before setting out by checking the Traffic Scotland website for up to date travel information.”
Numerous scheduled and emergency works will take place on single carriageway stretches of the A9 over the next eight years despite the overarching £3 billion upgrade scheme that will replace some of those stretches.
It will see 80 miles of single carriageway along the A9 between Perth and Inverness dualled by 2025.
