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, runs from the N4 at Lucan to the N81 at Tallaght, bypassing west of Clondalkin (around Grange Castle) and crossing the N7 near Citywest. It was built as part of the planning for the new town of Adamstown.
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.
