Resurfacing work will start in the middle of next month at the east end of Academy Street, from the entrance to the Victorian Market round to the bus stop at Falcon Square.
The work will start on Sunday October 13 and is expected to run until Thursday 17 October.
Highland Council has warned there are likely to be delays to traffic as the road will be reduced to a single lane which will be controlled by temporary traffic lights.
Access for emergency services will be maintained.
The work site will be fenced off but adjacent footpaths on both sides of the road will be available to pedestrians throughout the works.
The two pedestrian crossings at Station Hotel and Marks & Spencer’s store will be suspended, but the crossings at Queensgate junction and Crown Road junction will remain in operation.
All taxi ranks on Academy Street within the works area will be relocated to Station Lane at the rear of the railway station temporarily.
Advanced warning signs will be erected a week before the work starts.
A Highland Council spokeswoman said: “The council apologises for any inconvenience during the works which will however result in a new and improved road surface on Academy Street.”
