R148 road

R148 road

R148 Destinations (E to W) Length 45 km

The R148 is one of Ireland's regional roads which was classified following the opening of a by-passed National Primary route.

The section of the old N4 which has been by-passed by the M4 motorway was reclassified R148. The R148 runs from Dublin to Kinnegad in County Westmeath.

The road is long. It is generally of a very high standard for a regional road, with wide lanes, hard shoulders, and turning bays. It is still heavily used by traffic avoiding the tolled M4 between Kilcock and Kinnegad.

The road was previously categorised as a National Primary route until the opening of the M4 motorway and therefore carried a speed limit of 100 km/h. The speed limit has now been reduced to 80 km/h. The fact that speed limits have reduced, even though traffic is lighter than before, has led some to claim that the limit reduction is simply a cynical attempt to force motorists to use the tolled M4. This argument is perhaps strengthened by the fact that the R148 is due to receive a large share of the speed cameras due to be rolled out across Irish roads in 2008.

Route

The route starts (east-west) in Lucan, County Dublin at the same grade separated interchange at which the M4 begins. Less than 1 km west it crosses the River Liffey into Leixlip in County Kildare.

It then passes through Leixlip, Maynooth, Kilcock, Enfield and Clonard before rejoining the N4 west of Kinnegad.
