T and L roads (Ireland)

From Roader's Digest: The SABRE Wiki
Jump to navigation Jump to search

First- and second-class roads in the Republic of Ireland (and, before that, the Irish Free State) were originally classified as respectively Trunk (T) and Link (L) roads.

Road numbers pre-dated the partition of Ireland with the formation of the Road Committee by Ministry of Transport Act 1919. A 1926 act, post-partition, refers to "The route letter and number of a road", suggesting that roads had begun to be classified but had not been widespread. Route numbers were added to the edge of fingerposts signs, which were put at junctions. They were notorious for being over-detailed, intermittent and having too many signs in one place, resulting in tourists getting frequently lost.

T roads between 1 and 8 were radial routes from Dublin, while others were cross-country routes roughly in decreasing order of importance.

Trunk and Link roads were never formally written into law. In the late 1960s, the government planned to introduce a formal national road network. Trunk and Link roads were phased out in 1977, to be replaced by a comprehensive new classification system of National, Regional, and Local roads.
