The M9 motorway (Irish: Mótarbhealach M9) is a motorway in Ireland linking the M7 between Naas and Newbridge near Kilcullen to Waterford. Opened in sections between 1994 and 2010, the final section opened on 9 September 2010.
Prior to July 2008, the majority of the M9 – from Junction 2 onwards – was to be built as High Quality Dual Carriageway (HQDC). Due to the passing of a Statutory Instrument in that month, a large section of the route was re-designated to motorway standard. The section included the motorway between Kilcullen and Powerstown and the Carlow bypass. The remainder of the route has since been redesignated.
The M9 begins at Junction 11 (previously Junction 9) on the M7 motorway. This junction is a restricted access interchange, allowing traffic from the M9 to enter only the eastbound carriageway. There is no access to the M9 from the M7 eastbound, or to the M7 westbound from the M9. The route continues for 6 km before reaching the Kilcullen to Carlow section. The section runs between Junctions 1 and 2 on the M9 corridor. This section opened on 24 October 1994.
Construction of 28 km of motorway linking the Kilcullen bypass with the Carlow bypass began in February 2008. This section was completed and opened on 21 December 2009.[1] It runs between Junctions 2 and 4 on the M9 corridor.
This 18.5 km (11 mi) section of motorway opened on 29 May 2008 and runs between Junctions 4 and 6 on the M9 corridor. It provides a bypass of Carlow and allows access to the N80 for Rosslare and the R448 for Leighlinbridge.[2]
The first part of this section between Junctions 9 and 10 (Danesfort-Knocktopher) comprising 12 km of motorway was opened on 22 March 2010, in conjunction with the Knocktopher to Waterford section. The remaining section, Leighlinbridge to Danesfort, opened on 9 September 2010, thus completing the entire motorway. The scheme was built by SiskRoadbridge(SRB) Ltd.
The Knocktopher-Waterford section of the M9 route was opened on 22 March 2010.[3] This section is 24 km long and runs between Junctions 10 and 12 on the M9 corridor. The scheme was built by BAM Ltd (formerly Ascon Ltd.). Junction 12 is not a standard motorway junction but is instead a roundabout. The left exit from this roundabout accesses the N9 road which continues to Waterford.
