## Project summary

Transport Infrastructure Ireland’s December 2024 Major Roads & Greenways Projects Active List identifies “N25 Midleton to Youghal (bypasses Castlemartyr)” in Cork, on the N25 from Lakeview Roundabout in Midleton to the Youghal Bypass at Ballyvergan. The entry lists the project at Phase 1 Concept & Feasibility. Its length is circa 20 km but remains to be determined, the cross-section is undetermined, and route options are under development. Potential Castlemartyr and Killeagh bypasses and multi-modal transport solutions are identified for further assessment; none is confirmed as selected scope.

The listed next IG Gateway is Gate 1 Approval in Principle; the entry does not report that it has been achieved. Construction is listed as post-2030, with timing to be confirmed. The forecast cost range is TBC, subject to planning and design, and the benefit-cost ratio is pending project development.

The entry describes congestion and safety concerns and reports AADT in excess of 17,000 at Castlemartyr, with heavy goods vehicles accounting for 5%, AADT of 13,000 east of Killeagh, and identified High Collision Locations on this N25 section. Decarbonisation, lower greenhouse-gas emissions, and improved air and noise quality are presented as objectives or anticipated benefits, not achieved outcomes.

## Evidence limits and unknowns

- The final route, length, cross-section, and whether either potential bypass or multi-modal solutions will form part of the selected project are not established in the December 2024 entry.
- The entry lists Gate 1 Approval in Principle as the next gateway but does not give its outcome or establish whether approval has since been obtained.
- The December 2024 entry does not establish later project status, procurement, financing, or project roles.
- This account covers the December 2024 list’s cover and N25 project entry (pp. 1 and 23); other pages and graphical content were not assessed.
