Our National Road Network

Transport Infrastructure Ireland operates, maintains and improves the national primary and secondary road network in Ireland.

Ireland's Primary and Secondary Road Network

The primary and secondary road network in Ireland is some 5,306km long and is made up of motorways, dual carriageways and single lane roads. Approximately 320km of the 916km motorway network is being operated by Public Private Partnerships.

Other sections are managed by Motorway Maintenance and Renewal Contract operators. Our network carries approximately 45% of the country's total road traffic and most of Ireland's freight is distributed by road.
