Motorists are being advised to expect delays as resurfacing works start on the A9.
Bear Scotland have invested £230,000 to repair a 0.62-miles (1km) section of the busy Inverness to Thurso trunk road, south of the Cromarty Bridge.
The project of overnight work will continue between the hours of 8pm and 7am each night, with no work programmed to take place over the weekend.
Ground works are expected to be completed by next Friday.
Eddie Ross, BEAR Scotland’s North West Representative, said: “This £230,000 essential resurfacing project will upgrade the existing road surface on the A9 at Cromarty, greatly improving the quality and safety for road users.
“We’ve changed our ways of working to ensure all staff and the local community are kept safe at all times, and all personnel will be subject to strict physical distancing protocols in line with Scottish Government guidance.
“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.”
A 10mph convoy system will remain in place during the course of the work, between 8pm and 7pm each night, followed by a 30mph speed restriction during the day as vehicles travel over a temporary surface.
Throughout the duration of the project, the B9163 Conon Bridge junction and the B9163 Cromarty junction will be closed overnight to maintain safety for motorists and roadworkers.
A signed diversion route will be in place along the B9169 via the Culbokie Junction and the B9169 via the Easter Kinkell Junction, and then the A835.
