A1 Belfast - The Border

This article is about the Northern Irish A1. You may be looking for the British, Manx or Jersey road with this number. road with this number.

Route

A1 north of Newry

The A1 is part of the historic postal route from Belfast to Dublin, although the northern section is now shadowed by the A12 Westlink and M1.

It starts outside Belfast City Hall and heads southwest through suburbia as far as Lisburn before diverging from the M1's route at junction 7, heading south towards Banbridge and Newry. This was the last remaining section of single carriageway between Belfast and Dublin, but was completed to dual carriageway in mid 2010.

After the Newry Bypass, the A1 crosses the border and becomes the N1, leading to the Republic's M1 towards Dublin. However, the border does funny things in this area and the next junction south straddles the border, with a short section of the northbound N1 actually in Northern Ireland.
