R132

The R132 follows the former route of the N1 from Parnell Street in Dublin to the border with Northern Ireland at Carrickcarnan in County Louth, where it terminates at an end-on junction with the eastern B113.

Dublin area

Frederick Street remains part of the R132 despite not being open to general traffic.

O'Connell Street itself was part of the N1, but is now unclassified. The R132 instead starts at Parnell Square, looping round from there to Dorset Street. This was where the Inner Tangent would have seen a tunnel running eastbound only under the Rotunda Hospital, with westbound traffic meeting the surface streets as it does now.

From Dorset Street, the road heads in a straight line, and is mostly built as it was envisaged. It is a mixture of urban dual carriageway and single carriageway, generally to S4 standard.

A notable exception is the lack of a motorway flyover at Bins Bridge, as was proposed in the Dublin Transportation Plan. Traffic on the R132 would have had the option of joining the motorway in either direction, or following the sliproads through to Summerhill. The motorways would have taken most of the traffic, perhaps explaining why nothing was planned for Dorset Street.

Some old, green signs on Drumcondra Road.

As the road drops into Drumcondra village, it crosses the River Tolka on the newly-named Frank Flood Bridge. It then begins to rise, passing the university campuses, and experiencing two major traffic light junctions at Griffith Avenue and Collins Avenue, which can be major sources of congestion.

The Santry Bypass was the start of the M1, now M50, so the R132 can take the older route through Santry. There are lots of industrial estates around the airport, where the road has clearly been upgraded several times. At Swords, Airside Retail Park is the main view, with the R132 bypassing Swords itself, on a dual carriageway which runs up to the M1.

Gormanston

The route includes a 1-km-long spur connection to Junction 7 of the M1 at Gormanston.

Dundalk

Initially, the R132 was routed through the centre of the town, while the N52 was routed along the eastern bypass. In 2012, a statutory instrument was passed which reclassifies the eastern bypass as the R132, and renumbers the route through the town centre as the R215. However, the renumbering has not, as of 2019, taken place on the ground.

Feede - Drumad

This section of the N1 to the north of County Louth was upgraded to motorway standard (although to N1 rather than being made a motorway) without a parallel local access road being constructed. The old road was converted into a cycle and footpath and runs alongside the present N1 to the east. Further east, on the other side of the River Feede, a local road exists via Marble Bridge that other non motorway traffic can use. This has resulted in a gap in the R132, which continues north from J20 through Carrickcarnan to the Louth/Armagh border at Killeen, where the B113 continues towards Newry.

An amended OpenStreetMap trace for this route awaits uploading to the SABRE Wiki.
