The M50 motorway is a C-shaped orbital motorway in Dublin and the busiest motorway in Ireland. The current route was built in various sections over the course of 27 years, from 1983 to 2010. It begins at Dublin Port, running northward through the Dublin Port Tunnel and along a portion of the Airport Motorway. It then turns west at its junction with the M1, circling the northern, western and southern suburbs of Dublin, before merging with the M11 at Shankill in South East Dublin. The road forms 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. Driving is on the left-hand side of the road. 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.
The N7 road is a national primary road in Ireland, connecting Limerick and Dublin. The majority of the route is motorway standard and is designated as the M7 motorway. At the Rosbrien interchange in Limerick the route continues as the N18 dual carriageway to Galway, Shannon and Ennis. The road passes through the midlands of Ireland, and acts as a trunk route out of Dublin for the N8 and N9 national primary routes to Cork and Waterford respectively. It forms part of European route E20.
The M7 motorway is a motorway in Ireland. The motorway runs continuously from the outskirts of Naas in County Kildare to Rossbrien on the outskirts of Limerick city. The M7 forms part of the Dublin to Limerick N7 national primary road. The section of the motorway bypassing Naas, an 8 km stretch, was the first section of motorway to open in Ireland, in 1983. Following substantial works to extend the M7 to Limerick, by the end of 2010, the motorway replaced all of the old single-carriageway N7 route which is now designated as R445. At 166.5 km, the M7 is the longest motorway in Ireland.
The N8 road is a national primary road in Ireland, connecting Cork with Dublin via the M7. The N8 is further classified by the United Nations as the entirety of the European route E 201, part of the trans-Europe International E-road network. The road is motorway standard from junction 19 on the M7 to the Dunkettle interchange in Cork City and is designated as the M8 motorway. From here the route continues into Cork city centre and terminates at the N22 road at St. Patrick's Street. The M8 motorway was completed in May 2010, replacing the single carriageway sections of the old N8 and bypassing towns on the main Cork to Dublin road. It is now possible to travel from Cork to Dublin on the M/N8 in about 2 hours 30 minutes. The route commences just south of Portlaoise, and reaches Cork via the midlands and the Golden Vale, through counties Laois, Kilkenny, Tipperary, Limerick and Cork.
The N22 road is a national primary road in Ireland which goes through counties Kerry and Cork, from Tralee in the west through Killarney, Macroom and Ballincollig to Cork City Centre in the east.
Carrigaline is a town and civil parish in County Cork, Ireland, situated on the River Owenabue. Located about 12 kilometres (7.5 mi) south of Cork city, and with a population of 18,239 people, it is one of the largest commuter towns in the county. The R611 regional road passes through the town, and it is just off the N28 national primary route to Ringaskiddy. Carrigaline grew rapidly in the late 20th century, from a village of a few hundred people into a thriving commuter town although some locals still refer to it as "the village". The town is one of the key gateways to west Cork, especially for those who arrive by ferry from France. Carrigaline is within the Cork South-Central Dáil constituency.
Ringaskiddy is a village in County Cork, Ireland.

The village is a port with passenger ferry, with two bi-weekly sailings to Roscoff in France. A ferry service to Swansea in Wales closed in 2012.
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.
The N21 road is a national primary road in Ireland. The route runs from the M20 outside Limerick to Tralee with connecting roads to other parts of County Kerry. It is 84.37 km (52.43 mi) in length. It runs through the towns of Abbeyfeale, Newcastle West, Adare and the village of Templeglantine. Prior to October 2010 the N21 also ran through the town of Castleisland. The town has since been bypassed. Rathkeale was also bypassed in 1992.

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.
The M8 motorway is an inter-urban motorway in Ireland, which forms part of the motorway from the capital Dublin to Cork city. The 149 km motorway commences in the townland of Aghaboe, County Laois and runs through the counties of Kilkenny, Tipperary and Limerick, terminating at the Dunkettle interchange in Cork City. First called for in the Road Needs Study (1998), it was later incorporated into the National Development Plan (2000–2006) and later still formed part of the Irish Government's Transport 21 plan for infrastructural development. The majority of the M8 (115 km) was built between 2006 and 2010. On 28 May 2010, the motorway was completed and had replaced almost all of the single-carriageway N8 except for a short section of urban road in Cork City.
Shanbally is a small village located in south east County Cork on the N28 road. Shanbally is home to a Catholic church, a primary school, a pub, a shop and Shamrocks GAA club. The village is located close to Ringaskiddy, Monkstown and Carrigaline.
In Ireland, the highest category of road is a motorway, indicated by the prefix M followed by a one- or two-digit number. The motorway network consists entirely of motorway-grade dual carriageways and is largely focused upon Dublin. There are also several three-lane motorways, while Ireland's busiest road, the M50, incorporates four-lane, five-lane, and six-lane stretches.
The R613 road is a regional road in Ireland which runs west-east from the N71 near Ballinhassig to the N28 in the centre of Ringaskiddy.
The N40 road is a national primary road in Cork City, Ireland. It is partial ring road skirting the southern suburbs of the city, from the N22 west of Ballincollig, via the Jack Lynch Tunnel under the River Lee, to the Dunkettle Interchange where it meets the N25 and N8/M8. The present N40 designation was created on 23 February 2012 via statutory instrument by renaming parts of the N22 and N25. The N40 serves as both a commuter route and a bypass of the city centre for traffic between parts southwest and east. The National Transport Strategy envisages building a "Cork North Ring Road" to complete the circuit in the 2030s.
