[OSM-talk-ie] Deriving reference numbers for L roads

I've come across a handy trick for determining the reference number for a L
road here in Tipperary - the county council
publishes the Speed Limit By-Laws; and nicely refers to most roads by the
L-ref value. The by-laws are available for free download off their website.

In most cases this makes it  rather easy to determine what the reference
number for a given road is if there's a speed-limit road-sign on it.

Not all county-councils seem to follow this practice of identifying the
roads in this manner, but where they do checking their By-Laws for such
information is rather useful.

hoping this helps,
