N52 road (Ireland)
(bypassed routes in italics)
The N52 road is a national secondary road in Ireland. It links the M7 motorway from just south of Nenagh, County Tipperary to the M1 motorway north of Dundalk in County Louth. The route forms a connection between the north east of Ireland and the mid west and traverses through the midlands of Ireland. The route also forms an interchange with the M6 at Kilbeggan and at Tyrrellspass, the N4 at Mullingar, the N3 at Kells, and the N2 at Ardee before continuing towards Dundalk.
The road is 218 km (135 mi) long.
Quality of Road
The road is mainly single carriageway two-lane throughout. It has some upgraded sections, but generally the standard is poor or very poor. It starts (from the southwest) at a grade separated junction with the M7 motorway and by-passes Nenagh on its western side as single carriageway. Past Nenagh it is generally a single carriageway with no shoulders all the way to Birr. Many sections of this part of the route are very poor through County Tipperary with sharp bends. The route from Birr to Tullamore was upgraded in recent years and has good alignment, hard shoulders and a good surface as has the section from Tullamore to Kilbeggan which was upgraded in the 1970s. At Tullamore the route forms a bypass of Mucklagh and Tullamore.
The road forms an interchange on the M6 motorway south of Kilbeggan and follows it eastwards to the Tyrrellspass exit. Prior to the opening of the M6 the route went through Kilbeggan town and went past the racecourse via Ballinagore From this junction it heads north to Mullingar as the Tyrrellspass eastern bypass. It then follows the old route for 10 km (6.2 mi) before forming the eastern by-pass of Mullingar (opened May 2007); joins the N4 dual-carriageway briefly before leaving to head east over a very poor road to Delvin, Kells and Ardee before reaching the M1 south of Dundalk. Two kilometers of dual-carriageway take it to the R132 (the old N1) from where it becomes the Dundalk eastern inner relief route, over a new bridge near the harbour and north to the N1.
The Tullamore bypass is a new 14 km (8.7 mi) single carriageway upgrade to the N52. The route leaves the existing N52 approximately 6 km (3.7 mi) southwest of Tullamore town, intersecting with the N80 road, crossing over the Grand Canal, before rejoining the N52 again 3 km (1.9 mi) north of the town. The scheme began construction in April 2008, and was completed in October 2009.
Four metal figures by sculptor Maurice Harron are located where the new roadway cuts through esker ridges. The figures represent symbols of learning and sanctity. Approaching from the north the 1st figure holds up a chalice, the 2nd a book, the 3rd a crosier and the 4th shows the release of a flock of birds representing souls.  The installation was funded by the percentage for arts scheme where 1% of the budget is allocated to roadside art.
Lack of priority
- At the N52 junction with the R162 in County Meath the N52 stops and joins the R162 regional road and then leaves it again 100m further south. At this junction the regional road is the main road and is of a higher quality than the National route which crosses it.
