There's also the chance a single segment of the road has several names. For example when crossing a bridge or a round-about. Never mind all local names vs official names, old names and translations.
Correct, and indeed having the same name on different sides of the same road. I just recalled another example from Edinburgh[0] where one side of the street is called "Lochrin Buildings" while the other side of the street is called "Gilmore Place" (then both sides of the street become Gilmore Place, which then invisibly changes its name to Granville Place before changing into Polwarth Gardens.
