R113 road (Ireland)

Route

The official description of the R113 from the Roads Act 1993 (Classification of Regional Roads) Order 2006 reads:

R113: Fonthill - Blackrock, County DublinBetween its junction with N4 at Fonthill and its junction with N7 at Newland's Cross via Fonthill Road North, Nangor Road and Fonthill Road South all in the county of South Dublinbetween its junction with N7 at Newland's Cross and its junction with N81 at Tallaght Bypass via Belgard Road and Belgard Road Extension all in the county of South Dublinbetween its junction with N81 at Tallaght Bypass in the county of South Dublin and its junction with N31 at Leopardstown Road in the county of DunLaoghaire - Rathdown via Old Bawn Road, Killininney Road, Saint Colmcille's Way, Scholarstown Road, Ballyboden Way, Taylor's Lane and Grange Road in the county of South Dublin: Grange Road, Brohenfield Road, Motorway Service Roads and Murphystown in the county of Dún Laoghaire–Rathdownbetween its junction with N31 at Brewery Road and its junction with N31 at Temple Road Blackrock via Leopardstown Road, Newtownpark Avenue, Stradbrook Road and Temple Hill all in the county of Dún Laoghaire–Rathdown

As of January 2008 based the latest Ordnance Survey map of Dublin (Sixth Edition, updated Sept 2005) and the 2006 legislation defining the route changes the former R113 route to:

Start at Temple Hill in Blackrock at its junction with the N31.

Top of Temple Hill fork to Stradbrook Road.

Turn right up into Newtownpark Avenue.

Up Newtownpark Avenue

Cross the N11 at White's Cross and proceed along Leopardstown Road to the roundabout at Brewery Road (N31)/Sandyford Industrial Estate junction.

Follow dual-carriageway (on the N31/Leopardstown Road) to J14 of the M50.

Cross the M50 and follow the western end of the Leopardstown Road to a new junction at Hillcrest/Kilgobbin Rd.

Goes sharp right at Hillcrest down the new Kilgobbin Road Extension (in the thumbnail), to a rotary junction over the M50 (J13 East).

Follows two parallel roads either side of the M50 (two-lane one-way roads, in effect a dual carriageway with the M50 in the median) to a dumbbell junction under the M50 (J13 West).

From here it goes west along Brehon Fields Road (part of the Green Route) and then follows Grange Road past Marlay Park; on to Taylor's Lane as far as Ballyboden roundabout, where it intersects the R115

Continues west along Ballyboden Way; Templeroan; Scholarstown Road to cross the M50 again at Junction 12 (Knocklyon).

Continues west along St. Collumkilles Rd; Scholarstown Link Rd to a junction with the R114 (Firhouse/Bohernabreena Roads).

Veers north along the Old Bawn Road and joins the N81 in Tallaght Town centre.

After following the N81 west for 0.5 km it branches north along the Belgard Road dual-carriageway as far as Newlands Cross.

It crosses the N7 through a set of traffic lights. at grade, and follows the Fonthill Rd north west bypassing central Clondalkin. Clondalkin/Fonthill railway station is located on R113 at this point.

It crosses the R134 at a double roundabout junction and follows the Fonthill Road North for 5 km (3.1 mi) before terminating at a grade separated junction (junction 2) with the N4 at Quarryvale/Liffey Valley Shopping Centre.

Plans to carry the road north, across the River Liffey, seem to have been abandoned. Possibly due to concerns that a "free" crossing just one kilometer upstream from the West-Link on the M50 would cause massive re-routing of traffic (and, of course, loss of West-Link revenue).

Note: As of 2008 the former R113 route via Ticknock, Tibradden, Rockbrock and Mount Venus is still partially signposted 'R113' and the new R113 is still partially signed as a variety of other regional routes.
