Wikipedia:Articles for deletion/Three Digit System of Highways in Puerto Rico
per NE2.  I was about to say what he said, pretty much word for word, but he beat me to it.  Most of the articles on state highway systems in the US have a section on the numbering pattern, and the vast majority of these (as far as I've seen) are unreferenced.  I haven't found the page on WSDOT's website yet that explains why the highways are numbered the way they are, probably because it doesn't exist.  But any state map can be used as a reference to say that a pattern exists.  That being said, calling it a "system" and having a separate article like this is |neologism-ish, and largely unnecessary.  When/if it is merged, it can probably be condensed a good deal
