Roadworks in two separate locations in Armagh city centre will begin on Monday.
The £70,000 resurfacing schemes will take place on the Shambles Roundabout and at Barrack Hill at its junction with Victoria Street.
To facilitate the work it will be necessary to close the Shambles Roundabout on both Monday, April 16 and Tuesday, April 17 at 7pm, with roads reopening each morning again at 6am.
Traffic diversions will be signposted along Abbey Street, Irish Street, Windmill Hill, Convent Road, Lower Irish Street, Ogle Street, Thomas Street, Market Street, College Street and Lonsdale Road.
HGV traffic wishing to travel through the city will be diverted via Ballycrummy Road, Killylea Road, Friary Road, Barrack Street, Mall West and Lonsdale Road.
The junction of Barrack Hill and Victoria Street will be closed on both Wednesday, April 18 and Thursday, April 19, from 7pm to 6am the following morning, with traffic being diverted onto Drumadd Terrace, Drumadd Road, College Hill and Mall West.
The Department has carefully programmed the works operations and traffic management arrangements on both schemes which will be carried out over night to minimise any inconvenience to the public, however motorists should be aware that some delays may be expected and that additional time should be allowed when planning any journeys.
Local access will be maintained during the improvements.
The above planned schemes are subject to favourable weather conditions, for information about this and other improvement schemes visit: http://www.trafficwatchni.com
