Aregional road (Irish:bóthar réigiúnach) in theRepublic of Ireland is a class of road not forming a major route (such as anational primary road ornational secondary road), but nevertheless forming a link in thenational route network. There are over 11,600 kilometres (7,200 miles) of regional roads.[1] Regional roads are numbered with three-digit route numbers, prefixed by "R" (e.g.R105). The equivalent road category inNorthern Ireland areB roads.

History

[edit]

Until 1977, classified roads in the Republic of Ireland were designated with one of two prefixes:"T" for trunk roads and "L" for link roads. TheLocal Government (Roads and Motorways) Act, 1974[2] authorised the designation of roads as national roads: in 1977, twenty-five national primary roads (N1-N25) and thirty-three national secondary roads (N51-N83) were initially designated under theLocal Government (Roads and Motorways) Act, 1974 (Declaration of National Roads) Order, 1977.[3]

Many of the remaining classified roads became regional roads, formally authorised under theRoads Act, 1993[4] (having been indicated as such on road signs on a non-statutory basis for some years previously) and their routes were designated underRoads Act, 1993 (Declaration of Regional Roads) Order, 1994.[5] The lateststatutory instrument designating the routes of regional roads was published in 2012.[6]

Other roads once classified as trunk or link roads eventually becamelocal roads.

Older signs showing the former trunk and link road designations are still to be seen in some locations. The L (for link road) prefix on these signs is not connected to the network of local roads currently in place.

Features

[edit]

Unlike national roads, regional roads are maintained by local county or city councils rather thanTransport Infrastructure Ireland. The vast majority of the regional road network is made up ofsingle-carriageway roads although some roads aredual-carriageway. Until the late 1990s, such roads were often in a very poor condition, although increased road maintenance funding to local councils has resulted in more frequent resurfacing of regional roads, as well as relaying and realignment on some routes.

Regional roads are generally subject to aspeed limit of 80 km/h (imperial equivalent 50 mph), rather than the 100 km/h (imperial equivalent 62.5 mph) for national roads. Prior to 20 January 2005, when Ireland adopted metric speed limits, national and regional roads had identical speed limits of 60 mph. Regional roads, however, pass through towns, villages and built-up areas frequently, so even lower local speed restrictions are often in place. However, certain regional roads, often sections of former national roads which have been bypassed bymotorways or other road improvements, have speed limits of 100 km/h. TheR132 (former N1) is an example of a Regional road with a 100 km/h speed limit.

As of 2009[update], directionalsignposting on some regional roads in Ireland remains poor, with even modern signage usually relying on fingerpost signposts located directly at junctions. However, work on improving signposting on regional roads has been continuing since 2003; routes which previously had the most deficient signposting were selected for upgrading first. In 2007, a total of "€7 million to continue progress on the regional roads signposting programme, which commenced in 2003" was granted to local authorities.[7]

High-capacity regional roads

[edit]

There are some higher-capacity (i.e. not just single-carriageway) sections of regional road, most notably theR113 (Belgard Road) andR445 (Old Naas Road), R132 Swords Inner By-pass andR136 Dublin Outer Ring Road which have sections of dual carriageway.

In some cases, important high-capacity urban routes are built or designated as regional roads, such as the mostly dual-carriagewayR710 Waterford Outer Ring Road, or theR774Greystones to theN11 link, which is dual-carriageway for its full length.

In many other cases, upgraded regional roads (for example,wide two-lane roads) were previously part of a national primary road, prior to the construction of a motorway or other bypass. In most cases, when a national primary road is changed by the creation of abypass (motorway or other), the road previously forming part of the route is reclassified as a regional road rather than as a local road.

Route definitions

[edit]
This section needs to beupdated. The reason given is: Various amendments made to the statutory instrument modifying certain route definitions. Please help update this article to reflect recent events or newly available information.(May 2025)

The current routes of all regional roads in Ireland – as defined by theRoads Act 1993 (Classification of Regional Roads) Order 2012 – are listed below. The statutory instrument specifies the start and end points of each route and the names of those townlands, villages, towns, and other settlements through which the route passes, as well as individual road names where necessary to establish the exact routing.
