Traffic to the International Airport from the M1 motorway roundabout at Moira is likely to experience delays during a new major roadworks programme.
The £1million A26 Glenavy Road improvement scheme at Upper Ballinderry is due to last up to five months.
Transport Minister Danny Kennedy said the scheme will “help improve road safety and traffic flow” on a busy stretch of road.
“The improvements will include a realignment of the Ballinderry Road and provision of right turn pockets on the A26 Glenavy Road for vehicles entering the Ballinderry and Lower Ballinderry Roads,” he said.
Mr Kennedy said the works have been programmed to minimise traffic delays, but that drivers should note that lane restrictions will be in place at off-peak times and should allow some extra time for their journeys along this route.
The works will be carried out by civil engineering contractor Gibson (Banbridge) Ltd.
