The M1 motorway is a motorway in Ireland. It forms the large majority of the N1 national primary road connecting Dublin towards Belfast along the east of the island of Ireland. The route heads north via Swords, Drogheda and Dundalk to the Northern Irish border just south of Newry in County Armagh, where it joins the A1 road and further on, the M1 motorway in Northern Ireland. It also forms a significant part of the road connection between Dublin and the Northern Irish cities of Newry, and Lisburn. The route is part of European route E01.
The island of Ireland, comprising Northern Ireland and the Republic of Ireland, has an extensive network of tens of thousands of kilometres of public roads, usually surfaced. These roads have been developed and modernised over centuries, from trackways suitable only for walkers and horses, to surfaced roads including modern motorways. The major routes were established before Irish independence and consequently take little cognisance of the border other than a change of identification number and street furniture. Northern Ireland has had motorways since 1962, and has a well-developed network of primary, secondary and local routes. The Republic started work on its motorway network in the early 1980s; and historically, the road network there was once somewhat less well developed. However, the Celtic Tiger economic boom and an influx of European Union structural funding, saw national roads and regional roads in the Republic come up to international standard quite quickly. In the mid-1990s, for example, the Republic went from having only a few short sections of motorway to a network of motorways, dual carriageways and other improvements on most major routes as part of a National Development Plan. Road construction in Northern Ireland now tends to proceed at a slower pace than in the Republic, although a number of important bypasses and upgrades to dual carriageway have recently been completed or are about to begin.
National Development Plan was the title given by the Irish Government to a scheme of organised large-scale expenditure on (mainly) national infrastructure. The first five-year plan ran from 1988 to 1993, the second was a six-year plan from 1994 to 1999 and the third ran as a seven-year plan from 2000 to 2006. A fourth National Development Plan ran from 2007 to 2011. The main elements of the third plan were the development of a national motorway network between the major cities in Ireland. The upgrading of the rail network was a secondary scheme.
The N4 road is a national primary road in Ireland, running from Dublin to the northwest of Ireland and Sligo town. The M6 to Galway diverges from this route after Kinnegad, while the N5 to Westport diverges at Longford town. The section of the N4 that is motorway-standard is designated the M4 motorway.
A dual carriageway or divided highway is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation. Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways.
The A3 is a motorway in northeast Switzerland, running diagonally from France toward the southeast border, and passing by Zürich on the way. The total length of the A3 motorway spans roughly 180 kilometres (110 mi), but parts of the road share sections of the A1 and A2 motorways.
The A13 is a motorway, at times an Autostrasse (expressway), which runs from St. Margrethen in northeastern Switzerland through to Ascona in southern Switzerland, crossing the main chain of the Alps in the Grisons area. It is the southern half of European route E43.
The N3 road is a national primary road in Ireland, running between Dublin, Cavan and the border with County Fermanagh. The A509 and A46 roads in Northern Ireland form part of an overall route connecting to Enniskillen, and northwest to the border again where the N3 reappears to serve Ballyshannon in County Donegal.
The N1 is a national route in South Africa that runs from Cape Town through Bloemfontein, Johannesburg, Pretoria and Polokwane to Beit Bridge on the border with Zimbabwe. It forms the first section of the famed Cape to Cairo Road.
The European route E 20 is part of the United Nations International E-road network.
The N18 road is a national primary road in Ireland, connecting the cities of Limerick and Galway. Ennis and Gort are two major towns on the route, and Shannon Airport is reached via the connecting N19. The west coast route continues on to Sligo as the N17. The section from Limerick to the N19 junction forms part of European route E20, and the entire route is part of the proposed Atlantic Corridor. The section of motorway from Shannon to Claregalway is designated the M18 motorway. The tolled Limerick Tunnel forms part of the route.
A national primary road is a road classification in Ireland. National primary roads form the major routes between the major urban centres. There are 2649 km of national primary roads. This category of road has the prefix "N" followed by one or two digits. Motorways are prefixed "M" followed by one or two digits.
Mollis is a former municipality in the canton of Glarus in Switzerland. Effective from 1 January 2011, Mollis is part of the municipality of Glarus Nord.
The A505 is an A-class road in England. It follows part of the route of the Icknield Way and the corresponding Icknield Way Path and runs from Leighton Buzzard, Bedfordshire to the A11, Cambridgeshire near Abington and Sawston. Being built in the East of England countryside, the majority of the road is flat, and some of the road is raised.
A High-quality dual carriageway (HQDC) is a category of road in Ireland. It is an all-purpose dual carriageway road type built to near motorway standards, but without motorway classification or motorway restrictions. High-quality dual carriageways have full grade-separated access and do not have junctions with minor roads. Such roads in the Republic of Ireland have been built as part of the 2000-2006 and 2007-2013 National Development Plans, including interurban routes from Dublin to other cities.
The A278 is a road running north-south in north Kent, England. The whole length of the road is dual carriageway, within Medway Council but is a non-primary route.
