The N20 road is a national primary road in Ireland, connecting the cities of Cork and Limerick. Buttevant, Croom, Charleville, Mallow and Blarney are major towns along the route. Part of the route is a motorway, designated as the M20 Motorway.

The route starts at junction 1 at the Rosbrien interchange (south of Limerick City) where it connects to the M7 and the N18 which form the Limerick Southern Ring Road. The route continues from this interchange as motorway (see thumbnail). This route was redesignated as motorway in August 2009. The route bypasses Dooradoyle and Raheen, through which the old N20 route used to run until the early 2000s. Interchanges and link roads connect to these locations. Two further interchanges are located on the motorway, at either end of Patrickswell. At the latter, the M/N20 route leaves the main road (which continues as the N21 to Tralee), i.e. one must turn off the dual carriageway to stay on the M/N20.
A wide two lane road brings traffic along the Croom bypass (prior to the opening of this bypass at a cost of €20 million on 12 July 2001, the route went through the town).[1] Past this new section of road, narrow two-lane road commences, ending at Charleville. The route passes through the town, running along Main Street. The road between Charleville and the next town, Buttevant is of similar design. At Mallow a relatively high specification road is encountered , with an older bypass of the town (early 1990s) passing up the hill from it as dual carriageway. A viaduct brings the road across the Blackwater River and Valley. The rest of the route to Cork is of high quality wide two lane, with a section of 2+1 road (a pilot installation) south of Mallow. The route becomes dual carriageway on the approach to Cork. New relief roads in Cork bring the route into the city centre while avoiding the winding streets through which the route ran until around 2000.

Under the government's collapsed Transport 21 initiative,[2] the Atlantic Corridor road project aimed to link Letterkenny to Waterford via Limerick and Cork with high quality roadway. A major part of this project involved the upgrading of the N20 route between Cork and Limerick.
It was proposed to upgrade or replace the entire N20 with a new M20 motorway, approximately 90 km (56 mi) in length, with up to eight newly constructed junctions or re-configured junctions. It was to be constructed in two stages: a southern section and a northern section.[3] It is hoped that this project will be progressed as a PPP scheme. Details of progress on the scheme can be found on the Cork National Roads Office website.[4]
The first segment of M20 motorway came into existence on 28 August 2009 following the approval by the Minister for Transport to redesignate a 10 km (6 mi) of existing N20 dual-carriageway between Rossbrien and Attyflin as motorway.[5]
On 10 November 2011, owing to funding issues caused by the current financial crisis in Ireland, the government announced that the planned completion of the M20 motorway is to be shelved for the foreseeable future, along with a number of other insfrastructural projects.
