Older signs showing the former Trunk and Link road designations are still to be seen in some locations.
Regional roads, however, pass through towns, villages and built-up areas frequently, so even lower local speed restrictions are often in place.
As of 2009[update], directional signposting on some regional roads in Ireland remains poor, with even modern signage usually relying on fingerpost signposts located directly at junctions.
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.
In some cases, important high-capacity urban routes are built or designated as regional roads, such as the mostly dual-carriageway R710 Waterford Outer Ring Road, or the R774 Greystones to the N11 link, which is dual-carriageway for its full length.
