National Primary Route 22

The county of Kerry suffers from poor access. Towns such as Dingle. Cahersiveen, Listowel, and even large Tralee are far from any major trunk routes. Dual carriageway penetrating the county as far as Tralee and coming from both the Limerick and Cork directions would do much to redress this problem. The distances involved are great, however: over 100 kilometres would be needed. The N22 is programmed for some improvements west of Cork city, but since the 2010 spending review only the Ballyvourney-Macroom section is secure. There is no specific plan for the route west of that as far as Tralee, but a dual carriageway will eventually be needed.
