R136 road

From Wikipedia, the free encyclopedia

A junction along the R136 Outer Ring Road at Grange Castle.

The R136 road is a regional road in the Ireland, located in the southwest of Dublin. The route is named the Outer Ring Road, the route (which is dual carriageway) bypasses west of Clondalkin (around Grange Castle) connecting the N4 to the Naas Road (N7). It was built as part of the planning for the new town of Adamstown.

[edit] Route

The route was legislated in 2006 as commencing along the R835 near Lucan (Adamstown), 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 a short section between the N4 and Ballyowen Shopping Centre. However the section between Ballyowen and Adamstown has only one traffic lane and a bus lane in each direction. (This is still a dual carriageway, there is a central median). From Adamstown to Kingswood, the route has two lanes and a bus lane in each direction. However all junctions, other than the two terminal junctions, 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.

[edit] Plans

The planned extension to the outer ring road is to be single carriageway with bus and cycle lanes. Phase 3 will continue the outer ring road south from the Kingswood Interchange (N7 J2) to the N81 Tallaght Bypass in Tallaght.
