text: Thanks.   As for dead end, I'm not sure, I was just noting what I saw as I was riding by.   Reading the wiki with the usual 100 grams of salt, it seems noexit=yes is used when the end is close to something else that there's a valid armchair question if it should be connected, but that's no the case there.   There are tags for signs, but I don't see dead end on the list. 
  
  I guess there might or might not be a turning circle, but I didn't see anything, so that's not part of this.
