The dual-carriageway ends after bypassing Midleton with an ordinary two-lane road continuing east to Youghal.

This consisted of widening of 3.5 kilometers of single carriageway to include a hard shoulder on both sides of the road.

[7] East of the town, the N30 diverges and connects northeast to Enniscorthy, Clonroche and the M11 Dublin – Wexford motorway.

Part of the N25 dual carriageway in Midleton is to have all its junctions grade-separated and all direct accesses removed from the route (by the construction of a parallel road), thus making it suitable for upgrade to motorway status.

[citation needed] As of the early 21st century, TII was examining the possibility of a new road from Midleton to Youghal, with route options being investigated.

[10] On 27 March 2017, a light aircraft crashed in a field adjacent to the road, killing the elderly pilot.
