The Department for Infrastructure has announced a major resurfacing programme for the southbound carriageway of the A1 Banbridge Bypass, stretching between the Rathfriland Road Junction and the Newry Road (The Boulevard Outlet) Junction.

The works are scheduled to take place from 17 April to 29 April 2026, with the majority of operations conducted overnight and over weekends to minimise disruption.

Infrastructure Minister Liz Kimmins stated: "This is a substantial investment for our major road network. The A1 carries thousands of vehicles per day including many cross border travellers. These essential resurfacing works will deliver significant benefits for all road users and demonstrates my commitment to improving our road network, which is vital for connecting our businesses and communities. I would like to thank all local residents, businesses and those who travel along the A1 for their patience while this essential infrastructure work is carried out."
