I don't agree, since it was very annoying for me there with the bike (had to go back to Mariedal). There are signs everywhere, especially for people on bikes to use the southern route if the bicycle boat is out of season. So even if it might be illegal, thats how the municipality handles it.

(But: I cant check how exactly it is tagged atm, just wanted to make sure, that the bicycle route doesnt follow this way, so consider resolving/closing this again)
