Until 1977, roads in

were designated with one of two prefixes:
"T" for trunk roads and "L" for link roads. Older signs showing the former trunk and link road designations may still be seen in some locations. The L- prefix for "link road" on these signs does not stand for "local road".
The Local Government (Roads and Motorways) Act, 1974 authorised the designation of roads as national roads: in 1977, 25 national primary roads (N1–N25) and 33 national secondary roads (N51–N83) were initially designated under Statutory Instrument S.I. No. 164/1977.
Many of the remaining classified roads became regional roads (formally authorised under the Roads Act 1993, route numbers having been present on road signs on a non-statutory basis for some years previously) and their routes were designated under a
Statutory Instrument in 1994.

Local roads vary greatly in quality, from wide urban streets to very narrow, rural lanes, known as
boreens in Ireland. There are three types of local roads: local primary (local roads wider than four metres), local secondary (local roads narrower than four metres) and local tertiary (

Local road numbering

The Roads Act 1993 gives local authorities the duty to "assign a number or other identifying mark to each local road in respect of which it has a responsibility". Local road numbers have been used for administrative purposes since the Act came into effect, but local road numbers did not generally appear on directional
signposts until the late 2000s. Most road maps do not show local road numbers, although some are marked on

Local roads are classified by the road authority for the area as local primary, local secondary or local tertiary roads. The local primary roads are numbered from L1000 – L4999. Local secondary roads are numbered from L5000 – L8999. Local tertiary roads are numbered from L10001 – L89999, with the first four digits representing the local primary or secondary road to which it is connected. Local tertiary roads which are unrelated to a local primary or secondary road are numbered from L90000 upwards. Local roads are divided into segments of two to three kilometres maximum. For this reason, they serve a limited function as the applicable L road number generally ends at junctions with other local roads. The numbering systems are not widely known to the public, however, they must be made available to the public upon request in accordance with section 10 of the Roads Act 1993.
Unlike national and regional roads in Ireland, local road numbers are unique within each administrative county but are not unique nationwide. For example, there is an L1001 in Kilcroney,
Bray, another in
Inch, County Wexford, another L1001 in
