It doesn't seems to fit the description of the wiki though, but maybe I'm not understanding what you are trying to tag, conceptually. What is the difference between strandslagen, strandafrit and strandslag ? 

From what I understand, it represents the "beach entrance", so the access way to the beach, is that correct ? If so, I don't really get what is the semantic difference between the existing higway line leading to the beach, and the node you added
