Specifications[edit] Standard motorways: 52,000 vehicles AADT - annual average daily traffic. The road type is all-purpose dual carriageway (D2AP), but with the same specifications as motorway: a carriageway width of 7 metres (23 ft) and a hard shoulder of 2.5 metres (8 ft 2 in) width. HQDCs are limited access (grade-separated junctions only) and not intended to have junctions with minor roads. Junctions with major roads are grade-separated and to motorway standards. All HQDCs in Ireland currently form part of national primary roads, and therefore use the national road speed limit of 100 km/h (62 mph). There are exceptions however, as special speed limits may now be specified for sections of road if the local authority passes a by-law. For example, a section of the N1 from the northern end of the M1 motorway (north of Dundalk to the border with Northern Ireland) has a 120 km/h (75 mph) speed limit. Signage on Irish HQDCs is similar to signage used on Irish motorways, and junction numbers may be present (as on motorways, indicated by a white number on a black panel in the corner of signs). However signage on HQDCs uses a green background instead of the blue background used on Irish motorway signage. In the event of an HQDC being a regional road, black text on a white background would be used instead. Also, as on other all-purpose roads, signs should include patches for roads of other classifications (on motorways, all information signage should have a blue background). As high-quality dual carriageways are not motorways, they do not need to conform to motorway regulations, therefore slow-moving vehicles (e.g. tractors, farm vehicles etc.) as well as cyclists are permitted to use these roads. HQDCs have a hard shoulder marked with a broken yellow line (as is standard on Irish roads), rather than the solid yellow line used to mark the hard shoulder of an Irish motorway. Also, L-Drivers (Learner Drivers), who are not permitted to drive on motorways can do so on high-quality dual carriageways, as on the rest of the national road network. HQDCs are a road type, not a classification, and the normal rules and regulations applying to all-purpose roads apply on HQDCs. Lay-bys (rest stops) are permitted on HQDCs and the N6/M6 Kinnegad - Kilbeggan scheme originally featured lay-bys, which would not be legal at present on roads with full motorway status, prior to its redesignation as a motorway. The M9 Carlow bypass was built with lay-bys as it was originally to be built as an HQDC section of the N9 route. The lay-bys were removed after the road was reclassified as a motorway. Lay-bys on other HQDCs which were reclassified as motorways were restricted to authorised vehicles only and are likely to be used mainly by Garda Síochána (police) patrol vehicles. High Quality Dual Carriageways with Motorway Speed Limits in Ireland[edit] The standard speed limit for cars on Irish motorways is 120 km/h (with a minimum speed limit for any type of vehicle of 50 km/h - 31 mph). The standard speed limit on national roads is 100 km/h (62 mph). A number of local authorities have passed special speed limit by-laws permitting dual carriageways in their administrative area to carry motorway speed limits of 120 km/h (75 mph).

HQDCs on Major Inter-Urban Routes[edit] N11 HQDC Gorey Bypass prior to re-designation as M11 motorway. Many of the Major Inter-Urban Routes between Dublin and other cities in Ireland[1] were originally to be built to motorway standard but without motorway restrictions, and were to be designated as HQDCs. Roads that were to be built as HQDC include the N6/M6 Kinnegad - Athlone scheme (completed in July 2008), the M8 Mitchelstown - Cashel scheme (completed in October 2008) and the M9 Carlow bypass scheme (completed in June 2008). These roads will form part of the major inter-urban routes network. The advantage of an HQDC over a motorway in this regard is that a simpler planning permission process is used, rather than the more complex Motorway Scheme process used to create a motorway. However the problem of using the normal planning process is that in theory planning permission could be granted for a direct access for a home or business onto the HQDC; although such direct accesses are now discouraged under public policy there is no legal impediment. Motorways, by contrast, may only have accesses at junctions and service areas. HQDCs which form part of national road routes use the N (national road) prefix on signage as opposed to the M prefix used where the route or a section of it is motorway. Most of the HQDC sections on the major inter-urban network of roads in Ireland have been redesignated as motorways or have been proposed for redesignation.

Redesignation as motorway[edit] In 2007 new legislation was introduced to allow the Government to designate HQDCs as motorways and thus avoid the risk of permission for direct access being granted by local planning authorities.[2] The Roads Act 2007 was passed by the Oireachtas in early 2007 and signed into law to by the President of Ireland on 11 July 2007. The Act introduced powers for the Minister for Transport (on the recommendation of Transport Infrastructure Ireland) to re-designate high quality dual carriageways as motorways, following a public consultation process. It is possible that in the future a majority of HQDCs will be reclassified as motorways.[3] A number of the former high-quality dual carriageway schemes proceeded as tolled motorway PPPs (Public Private Partnerships) despite not being originally planned as motorway schemes. Such roads include the M6 Galway - Ballinasloe project. The N25 Waterford City bypass is the only HQDC planned at present to be tolled. Almost all other Irish toll roads are motorways, although the East-Link toll bridge which is a regional road is also tolled. This section of the N8 5 km north of Cork was redesignated as motorway. The Roads Act 2007 was passed into law in mid-2007. This Act made provision for the redesignation of suitable dual carriageways to motorway status. The National Roads Authority made formal applications under Section 8 of the Act to the Minister for Transport on 16 October 2007 regarding dual carriageways which the authority believed to be suitable for redesignation as motorways. On 29 January 2008, the Department of Transport published notice of the Minister's intention to make the orders being sought and invited submissions or observations to be made to the Minister regarding the NRA's applications. The initial applications proposed the following roads be redesignated as motorways: Route Proposed motorway section Destinations N6 road Kinnegad (M6 J2) – Athlone[4] (Dublin) – Galway N7 road South of Borris-in-Ossory to Annacotty[5] Dublin – Limerick N8 road Urlingford – Fermoy[6] (Dublin) – Cork N9 road Kilcullen – Waterford (junction with proposed N25 road)[7] (Dublin) – Waterford The consultation procession lasted until 28 March 2008. On 17 July 2008 the Minister signed a statutory instrument reclassifying all the HQDCs then either under construction or recently completed on the N7/M7, and N8/M8 as well as parts of the N6/M6 and N9/M9 as motorway.[8] The redesignations came into effect on September 24, 2008.[9] The Carlow bypass and Kilbeggan-Athlone roads opened with motorway signage but with temporary 100 km/h (62 mph) general speed limits between their opening and their official re-designation as motorways. These roads now operate under motorway restrictions with motorway signage and use the M prefix. The standard speed limit on these roads is now 120 km/h (75 mph). On 30 September 2008, the NRA proposed that the following dual-carriageways be re-designated as motorways: Route Proposed motorway section Destinations N2 road Junction 2 – north of Ashbourne[10] Dublin – Derry N3 road Mulhuddart – Dunboyne[11] Dublin – Ballyshannon N4 road Kinnegad – McNead's Bridge[12] Dublin – Sligo N6 road Athlone – Galway[13] (Dublin) – Galway N7 road Annacotty – Limerick[14] Dublin – Limerick N8 road Watergrasshill – Cork[15] (Dublin) – Cork N11 road Ashford – Rathnew and Arklow – Gorey[16] (Dublin) – Wexford N18 road Ennis – Galway[17] Limerick – Galway N20 road Limerick – Patrickswell[18] Limerick – Cork The closing date for submissions was 14 November 2008. The statutory instrument passed in early 2009 and will came into effect in mid-2009, with the exception of the N6 Athlone Bypass (remains dual-carriageway/HQDC).
