A major resurfacing scheme on the dual carriageway between Newry and Warrenpoint is expected to cause significant disruption when work gets underway next month.
But the £400,000 project will deliver significant improvements to both the structural integrity and surface of the road, according to the Department.
Resurfacing work will extend a distance of approximately one kilometer from close to the Mound Road roundabout at Warrenpoint, towards Newry.
Due to the nature of the scheme it will be necessary to implement the closure of Lane One and the hard shoulder from Monday, January 6, until Sunday, January 26, and the closure of Lane Two from Monday, January 27, until Friday, February 7.
Three weekend road closures from Mound Road roundabout to Aughnamoira Road will also be necessary, between 7pm and 6am from Friday, February 7, until Monday, February 10; Friday, February 14, until Monday, February 17; and Friday, February 21, until Monday, February 24.
During the weekend road closures a diversion will be in place via A2 Newry Road, Duke Street – ,Upper Dromore Road, Milltown Road, Bridge Road, Chapel Hill Road and Newry Road.
Cyclists are advised that during the duration of the resurfacing scheme the cycle lane will be suspended and a diversionary route for cyclists will be operational via Mound Road, Greenan Road and Old Warrenpoint Road, Newry.
Diversionary routes will be clearly signed and local access for residents will be maintained at all times during the works.
A spokesperson for the Department of Infrastructure said: “In order 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 Department has programmed the work and traffic management arrangements to minimise any inconvenience, however, drivers should expect some delays and are advised to leave additional time when planning any journeys.
“Completion by February 24 is dependent on favourable weather conditions.”
