# N-M20 Cork-to-Limerick project Publisher: CapexCue Canonical dossier: Dossier reference: release 1 (33a31511-2994-44b9-9a6a-82fbf2b65dc7) Released project intelligence Oldest supporting observation: 2026-10-03T09:45:21.338978+00:00 Dossier released: 2026-10-15T16:39:20.662676+00:00 Source report dates and capture dates are listed per fact below; neither establishes an event date. ## Project summary The N-M20 Cork-to-Limerick project is described as being advanced by Limerick City and County Council with Cork County Council, Cork City Council, Transport Infrastructure Ireland and the Department of Transport; formal implementation and ownership roles are not assigned. The preferred option describes 80 km of new and improved dual carriageway and 80 km of active-travel infrastructure. It combines reuse of parts of the existing N20 with bypass sections and ties into the existing M20 near Patrickswell. The option is 500 m wide; road type and junction strategy remain to be developed. The page describes Phase 3 as conditional on approvals and programmed for two years, with a later Phase 4 planning submission conditional on government approval; it supplies no start date for these steps. It also describes expected bus-service benefits and recommends, rather than confirms delivery of, an additional hourly rail service. ## Evidence limits and unknowns - The reviewed text does not give the project page's publication date, current approval status, current phase or a confirmed start date. Its forward-looking programme does not establish present status. - The precise alignment and road design are not settled beyond the 500 m-wide preferred option; road type and junction strategy remain to be developed. - The page does not specify financing, procurement, contractor or formal asset-ownership arrangements. - The supplied text does not establish that the described public-transport measures have been approved or delivered. - Linked documents and images were not assessed, and the whole document was not reviewed. Current purchasing availability: unknown. Source-dated plans do not establish current progress or available supplier packages. ## Project metadata Country: Ireland Region: Europe Physical assets: Road Derived from the exact released evidence; unresolved fields remain unclassified. ## Project category Transport and logistics Derived from the reviewed scope statement; delivery stage remains unclassified. The proposed road works comprise 80 km of new and improved dual carriageway between Cork City and Patrickswell, with 30%–40% reuse of the existing N20. The preferred option includes online reuse and offline bypass sections: it starts on the existing N20 between Cork City and Blarney, continues on the N20 to Mourneabbey, bypasses Mallow, New Twopothouse and Buttevant to the east, reuses the N20 north of Buttevant, bypasses Ballyhea, Charleville and Banoge to the west, reuses the Croom Bypass, and ties into the existing M20 at Attyflin near Patrickswell. The page also describes 80 km of active-travel infrastructure connecting communities along the corridor. Road type, junction strategy and other design elements remain to be developed within a 500 m-wide preferred option.

It recommends an additional hourly Cork–Limerick rail service via Limerick Junction, and describes mobility hubs integrating Mallow and Charleville rail stations and Park & Ride sites in Blarney and Raheen. The rail service is expressly a recommendation; the source does not establish that these public-transport measures are approved or delivered.

The active-travel corridor is described as connecting communities from Cork through to Limerick.

The page says consultation will continue through later phases; it does not report that the required approvals have been granted.

It says a formal planning submission to An Bord Pleanála would follow in Phase 4, subject to government approval. Engineering and environmental surveys are also described as future work to inform design, with direct consultation of potentially affected land and property owners as the design matures. No start date or evidence that these steps have commenced is supplied.
