The gateways are the main actors at national level. The strategy also designates hubs to support and extend the effect of the gateways. They are strategically located and also have the capacity to lead the development of their catchment areas. They take the form of either single or linked towns. This depends on location, size, population base and on the facilities, employment functions and services they offer, as well as their capacity for development. Linked gateways and linked hubs will require a co-ordinated approach to their development. This is a challenge to local authorities to adopt a new way of doing business. The linked hubs are Tralee-Killarney and Ballina-Castlebar. The other hubs are Cavan, Monaghan, Tuam, Ennis, Mallow, Kilkenny and Wexford.
