€34m bypass to divert 70% of traffic from Castleisland bottleneck
Castleisland is one of Kerry’s most notorious bottlenecks and the long-awaited bypass is projected to divert 70% of all traffic and more than three-quarters of heavy goods vehicles from the town centre. The 5.5km road bypasses Castleisland to the west of the town and links the Killarney, Limerick and Tralee roads.
The Limerick Road-Tralee Road section consists of 3.4km of dual carriageway, while a single carriageway links the N21 Tralee Road to the N23 Killarney Road.
