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 section runs between Junctions 1 and 2 on the M9 corridor. This section opened on 24 October 1994.
