A £435,000 resurfacing scheme on the Springmount Road, Clough, is due to start on Monday August 13.
The scheme which extends approximately 3.3km from the Old Frosses Road to Ballycregagh Road will deliver significant improvements to both the structural integrity and surface of the road, officials say.
Work is expected to be completed by 14 September 2018.
A full road closure will be in place for the duration of these works and traffic will be diverted via A26 Frosses Rd, Lisnasoo Road, Drumbare Road and Ballycregagh Road.
Diversionary routes will be signed and local access for residents will be maintained at all times during the works.
The Department has programmed the work operations to minimise inconvenience, however, drivers should expect some delays and are advised to allow additional time when travelling in the area.
To help ensure the safety of road users and road workers the public is asked to comply with all temporary traffic restrictions and to drive with care when travelling through, or in the vicinity, of the works.
The dates and duration of the works will be dependent on the progress of the scheme and on favourable weather conditions.
