National secondary road
From Wikipedia, the free encyclopedia
A national secondary road is a category of road in the Republic of Ireland. These roads form an important part of the national route network, but are secondary to the main arterial routes (which are classified as national primary roads. Secondary roads are designated route numbers higher than those used for primary roads, but with the same "N" prefix. Routes N51 and higher are all secondary roads.
National secondary roads have a default speed limit of 100 km/h, as along with national primary routes, they fall into the speed limit category of national roads.
Secondary routes are generally more poorly maintained than primary routes, but often carry more traffic than regional roads. Some sections of secondary roads (usually approaching urban centres) are dual-carriageway, while many are narrow two-lane country roads, indistinguishable from regional roads.
Many national secondary roads, though not arterial routes between major cities, connect large areas to major population centres. For example, the N59 through County Galway and County Mayo, the N70 road through County Kerry (see Ring of Kerry), the N71 through West Cork. For this reason, many national secondary roads are well-travelled by tourists.
