(the
M50 motorway being an inner ring road which should not be confused with the ''Inner Orbital Route'', an Inner Ring in the inner City). Phase 2, which opened in December 2006, commences at the
N4 road east of Lucan, passing through Ballyowen, with a junction for Adamstown, before linking up with the existing road at Grange Castle.
Almost the entire route is a
dual carriageway, apart from the bridge over the N4. From the N4 to
Adamstown, there is only one traffic lane and a bus lane in each direction (As the carriageways are separated by a

this is still technically a dual carriageway). From Adamstown to Kingswood, the route has two lanes and a bus lane in each direction. However all junctions, other than the N4 junction and N7 flyover, are at-grade, and the median is rather narrow.
The term ''Outer Ring Road'' should not be confused with ''
Outer Orbital Route'', which refers to an indicative plan to construct a second motorway bypass ring around Dublin (after the M50), further out from the city. Nor should it be confused with the existing ''Outer Orbital Route'' which circles the inner city in the

Line A1 to cross it (tracks in the roadway). This facilitated works on the line, which began in February 2009, to proceed without having to make any further alterations to the road.
Potential upgrades
Although provision had been made for the route to head further northwards, crossing the Liffey and joining the
R121 road at
Porterstown, the future bridge to be built linking these points will be for the proposed
Metro West only. Such a road link would have linked with existing relatively high grade sections of the R121 to provide a ring road link from Cherryhound at the M2 in the north west of Dublin's suburbs back to the N81 to the south west.
Planning dispute

When this road was being planned it was opposed by various interests.
[http://www.rte.ie/news/2001/0626/road.html Planning dispute 2001] It was eventually completed with the semi-rural section through
Grange Castle built as standard dual carriageway; two traffic lanes plus hard shoulder in each direction. It remained unopened for a time as Dublin City Council insisted that the bus lane run ''outside'' the hard shoulder so as to leave only one traffic lane (effectively the bus-lane would run down the centre of either carriageway). The local authority (South Dublin County Council) refused to open the road with such a bizarre arrangement and eventually the City Council relented.
