BEAR Scotland has announced a £320,000 resurfacing project on a kilometre of the A9 between the Pass of Drumochter and Dalwhinnie.
The scheme, around 1.5 miles north of Drumochter, is due to start next Tuesday (September 12) and take up to 12 days.
Resurfacing will be carried out between 7am and 7pm Monday to Thursdays, and 7am to 1pm each Friday.
No works are planned at the weekend, in order to minimise disruption during busier periods, and teams will also not be working on Monday, September 18, to avoid impacting traffic during the local Edinburgh holiday when roads may be busier.
Temporary traffic lights and a 10mph convoy traffic management system will operate while works are undertaken.
Traffic management will be removed outwith working hours to keep disruption to a minimum, although a speed restriction of 30mph will remain in place as traffic will be running on a temporary surface.
Eddie Ross, BEAR Scotland’s north west representative, said: "These improvements will help strengthen the road ahead of the winter period, and also create a smoother, safer journey for motorists.
"We’re aware of the impact our projects can have on the A9 in this area, so we’ve arranged this scheme to finish at 1pm each Friday and will also avoid working each weekend to reduce the impact to weekend road users.
"We’ve also taken into account the Edinburgh public holiday on Monday 18 and will avoid working that day to further lessen the impact of the scheme, which is essential to ensure this section of the A9 continues to function safely.
" It will deliver a smoother journey for motorists once complete.
"We thank motorists in advance for their patience and encourage them to plan ahead by checking the Traffic Scotland website for up to date traffic information."
