Not quite related to apostrophes, but I feel the need to point out my favourite street name of all time (as read on a street sign): St John St (-> Saint John Street)

I've seen Doctor King Drive (Dr King Dr) in a few different towns too. One of them typographically differentiated it like "DR King Dr" though.

Formally, that should be “St John St.”
