Dunkettle Interchange is a major road junction east of Cork city, at which the N8 meets the N25, M8 and the N40. It is

- junction 19 of the N8.
History
The roundabout was originally constructed as part of the offline dual carriageway works involving the N25 eastwards towards Midleton in the late 1980s. It was originally a simple at-grade roundabout, where the then N8 met the N25 and R623. It received an east - west flyover from the N25 to the N8 in 1997 and was linked to Jack Lynch tunnel (now N40) in 1999 to give its present layout. The roundabout was signalised in 2006. The HQDC N8 joining the interchange from the north was subsequently reclassifed as M8 and the route to the south has recently been reclassified as N40 (was N25).
In 2012, plans were announced for a comprehensive grade separation of the other routes. Clearance started in Jaunary 2018 and the road is expected to open in 2019.
