It runs from Belfast via Lisburn and Banbridge to the border with the Republic of Ireland south of Newry, from where the road continues to Dublin, becoming the N1 road and M1 motorway. Between Sprucefield and Carrickcarnan the road forms part of the European route E01. Recent developmentsThe A1 is fully dual carriageway but some junctions remain relatively low specification as they necessitate right-turning movements across the central reservation. The busier junctions have been improved by the provision of bridges or underpasses. A flyover was constructed at the busy Rathfriland Road junction in Banbridge and an underpass at the very dangerous Hillsborough road junction in Dromore was completed in June 2005.[1] Improved junctions at Banbridge and Hillsborough opened in September 2009, at Loughbrickland in December 2009[3] and at Banbridge Road, Dromore in February 2010.[4] The scheme involving the dualling of the A1 between Beech Hill and Cloghogue was completed in July 2010, five months ahead of schedule.[5] Planned developmentsThe Roads Service of Northern Ireland has planned to provide four further grade separated junctions. These schemes are located at:
Further measures envisaged to improve safety include a central reservation safety barrier to be constructed from the A1's junction with the M1 at Sprucefield to Loughbrickland. This will involve the closing of many of the dual carriageway's central cross-over points.[6] The Road Service also plan to improve the link between the M1 and A1 at Sprucefield in a scheme that would include a flyover at Hillsborough, the last remaining roundabout on the route between Dublin and Belfast.[7] References1. ^{{cite news | title=£4m underpass opens at accident blackspot | work=Belfast Telegraph | date=18 June 2005}} [2][3][4][5][6]2. ^1 {{Cite web | last = Johnston | first = Wesley | title = A1 grade separated junction, Dublin Road, Loughbrickland | work = Northern Ireland Roads site | date = 22 December 2009 | url = http://www.wesleyjohnston.com/roads/a1banbridgeroaddromore.html | accessdate = 2010-10-10}} 3. ^1 {{Cite web | last = Johnston | first = Wesley | title = A1 grade separated junction – Banbridge Road, Dromore | work = Northern Ireland Roads site | date = 6 February 2010 | url = http://www.wesleyjohnston.com/roads/a1banbridgeroaddromore.html | accessdate = 2010-10-10}} 4. ^1 {{Cite news | title = Newry bypass officially opens five months ahead of time | publisher = BBC News Online | date = 29 July 2010 | url = http://news.bbc.co.uk/1/hi/northern_ireland/8869244.stm | accessdate = 2010-10-10}} 5. ^1 {{Cite web |title = Eastern Seaboard Corridor – A1 Junctions Phase Two |year = 2008 |publisher = Northern Ireland Road Service |url = http://applications.drdni.gov.uk/publications/document.asp?docid=14402 |format = pdf |accessdate = 2010-10-10 |archive-url = https://web.archive.org/web/20110424084731/http://applications.drdni.gov.uk/publications/document.asp?docid=14402 |archive-date = 24 April 2011 |dead-url = yes |df = dmy-all}} 6. ^1 {{Cite web |title = Eastern Seaboard Corridor – M1/A1 Sprucefield By-Pass |year = 2008 |publisher = Northern Ireland Road Service |url = http://applications.drdni.gov.uk/publications/document.asp?docid=14415 |format = pdf |accessdate = 2010-10-10 |archive-url = https://web.archive.org/web/20110424084729/http://applications.drdni.gov.uk/publications/document.asp?docid=14415 |archive-date = 24 April 2011 |dead-url = yes |df = dmy-all}} }}{{Northern Ireland roads}}{{Coord|54.39665|N|6.17586|W|type:landmark_region:GB_dim:20000|display=title}}{{DEFAULTSORT:A1 Road (Northern Ireland)}} 4 : Roads in Northern Ireland|Roads in Belfast|Roads in County Armagh|Roads in County Down |
