Key commuter and delivery routes take priority over rest of network
Published 04/04/2011 | 05:00
IRELAND has almost 100,000 kilometres of roads, of which 5,500km are national routes.
The national routes carry more than half of all traffic, and are the key commuting routes and arteries for delivery of food, goods and fuel. Half are designated national primaries, which include motorways and dual carriageways; 2,700km are national secondary roads.
The secondary roads connect major towns and cities to each other and the national primary routes, while also providing accessibility to parts of the country with high tourism or amenity value.
National secondary roads carry medium to heavy volumes of traffic, with an annual average daily traffic of more than 2,000 vehicles.
The remaining 95,000km of roads include the lesser classed regional and local roads. Local authorities are responsible for upgrading and maintaining these routes.
