A stretch of the Buncrana Road will be closed over the coming two weekends to allow for new road surfacing.
The Department for Infrastructure has confirmed that the works are currently on schedule, and that weather permitting, will finish on August 19 as planned.
The confirmation follows concerns expressed locally that the works may cause major traffic chaos if there is any delay into September and the reopening of local schools.
Resurfacing work started on the Pennyburn section of the road on June 27, from the bottom of the Racecourse Road to the Pennyburn Roundabout.
A one way lane closure is currently in operation on the road from 9.30am to 6pm for traffic travelling towards the city, with diversions signposted.
Infrastructure Minister Chris Hazzard has previously confirmed that £160,000 has been allocated for the major scheme.
A spokesman for the his department said this week: “The work to date have been continuous and involved the installation of new drainage facilities and the raising of kerbs to facilitate the new surface and resurfacing of footways.
“The carriageway work will take place this weekend and next weekend, August 13-14, with a full road closure to allow the new road surface to be laid throughout the site.
“The remaining works, white lining and the resetting of ironwork will be done between 15 and 19 August.
“This work was specifically scheduled to be undertaken during the school holidays to avoid the potential disruption referred to.”
