Work is due to start on a major resurfacing scheme at the Portadown Road, Armagh, early next month.
Contractors – who will focus on a 900 metre stretch of carriagway – will move on site on Monday, October 2.
The improvements – which will also involve drainage upgrades and footpath repairs – will lead to various timed road closures, when diversions will be in place.
The scheme centres on the stretch from the Drumadd Road to the junction with Drummanmore Road.
It will be necessary to operate overnight road closures, from 8pm until 6.30am, from Monday, October 2 until Monday, October 16. The road will be open during daytime hours.
An alternative route will be signed with traffic being diverted via College Hill, Rokeby Green, Mall West, Gaol Square, Barrack Hill, Hamiltonsbawn Road, Annareagh Road, Legacorry Road and Portadown Road.
Local access for residents and emergency services will be maintained although some minor delays may be experienced.
Said a DfI spokesperson: “The Department has carefully planned these road works and associated traffic management arrangements in order to minimise inconvenience to the public.
“Road users are advised to allow extra time for their journey and to follow the alternative routes which will be clearly signed on the approaches to the closure.
“Completion of the work by 16 October 2023 is dependent on favourable weather conditions. The Department will keep the public informed of any change. All work will be carried out in line with current public health and safety advice, with safe systems of working in place for staff and contractors.”
