The R136 road is a regional road
in Ireland
, located in the southwest of Dublin. Named the Outer Ring Road, the route (which is dual carriageway

), and running south via Ballyowen Distributor Road and Grange Castle Road to Kingswood Interchange on the N7 (Junction 2). This forms "Phase 1" of the planned outer ring road
(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 as separated by a jersey barrier
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 Dublin City Council
area, outside the Inner Orbital Route.
Phase 3 of the road opened in July 2008, from the Kingswood
Interchange (N7 J2) to the N81
Tallaght Bypass in Tallaght
. This road was half a new build, half an upgrade of Cheeverstown Road and the junction of Cheeverstown Road and the N81. This section also included a provision for Luas
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.
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.
