Interesting idea, but then Resseldar’s suggestion of the number referring to a road doesn’t fit, as Wikipedia explains, they don’t have “A” roads in the RoI.
Roads in the Republic are classified as motorways (shown by the letter M followed by a route number, e.g. M7), national roads (shown by the letter N followed by a route number, e.g. N25), regional roads (shown by the letter R followed by a route number, e.g. R611) and local roads (shown by the letter L followed by a route number, e.g. L4202). There are two types of national roads: national primary routes and national secondary routes.
