Camlough Road Interchange is the junction between the A1 the A25 and the A27. This location had an overpass and a rather dangerous partial junction on the old S2 1996 Newry Bypass. When the bypass was upgraded to D2 in 2010, a new overpass was built and the previous one demolished. The old S2 bypass to the north of this junction became the A27 with the A1 redirected on a new build D2 extending towards the Carbane Interchange. The junction is close to the Dublin-Belfast railway with its distinctive Egyptian Arch.
