Toronto has Avenue Road.
I’m quite sure that the name of the street I live on is unique for the whole planet. It’s because it’s called after an old name for the landmark, like many, especially rural streets in Germany, after meadows, forests, creeks, ridges, mountains and so on.
I was going to mention that, while I don’t live on it, my city does have a street called Lois Lane.
A bit of Googling reveals, however, that there are a number of cities and towns that have such a street. So not unique, but still interesting.
That’s actually not far off from the name of the street I live on.
It’s nationally for mine, it’s not just Google maps.
The only place that shares the name of the street that I’ve been able to find is a tiny cluster of a few houses in Ireland, but that has a second part to the name as well.
There’s lots of tautological street names, such as that one, out there. Wikipedia, naturally, has a list. Some time back I greatly expanded this section and could have done even more, but I got tired of doing it.
A great many (perhaps most) streets in Hawaii have Hawaiian names, most of which are probably globally unique.
Names like Kalakaua Blvd., Kapiolani St., Piikoi St., Waialae Av., and Kalanianaole Highway.
A guy on Craigslist had some shit I wanted. It was close, so worth the trip. Called him up, got the address. Something like 1857 Bramstetter (or something similiar)
I get out there, met the guy, pick some shit, get to talking to him. His name is Daryll Bramstetter. I asked him if his family owned much of the property out there (kinda remote, down a desert road).
He says, “Nope. Just a coincidence”. Bramstetter? I poked a little on this, but he wouldn’t budge. Okay.
Lois Lane?
There is a street — well, a lane — called Lois Lane in a suburb of Fremantle, Western Australia. Like a lot of streets in Fremantle it’s named after a ship; the “Lois”, a three-masted barque of 393 tons that struck a reef and sank in 1890. I’m guessing the street was named before Superman was a thing.
The street sign is regularly stolen.
Toronto also has a number of streets that, when printed, have little relation to how they are pronounced.
Yonge Street: “Young” Street
Strachan Avenue: “Strawn” Avenue
Baby Point Road: “Bobby” Point Road
And then there are the thoroughfares in Toronto that, in spite of being designated as a road, avenue, or street, etc., take a definite article instead: The Danforth, The Lakeshore, for example.
Toronto is complicated. I lived there for forty years or more, and I get it. If you’ve never been there, and are visiting—you won’t get it.
I used to live on Sopadilla, which as far as I could figure was a misspelling of sapodilla, a tropical fruit. The neighboring streets were correctly spelled fruit trees.
Based on a quick google, the road I currently live on is the only one of that name; and the road I grew up on is also unique.
Anyone beat two?

As I mentioned, the street I live on now is unique, and the street I grew up on as well, as it’s also named after a neighboring village that has a unique name. The road I lived on in between is named after the river and its valley it follows, and is equally unique. So I’m up to three.
Looks like I’m at two, also.
The street where I grew up also seems to be unique in the US. It’s a much longer name, prepended with “East.” Without the “East,” it’s not unique. With it, it seems to be the only one in the country.
Well, that was a pretty brief moment in the limelight…

My late Mom, who was NOT a sports nut, lived on a very short dead end street when the town decided it had to have a name - the next door neighbor desperately wanted it named after his favorite basketball player, and she ended up with her home assigned the address 4 Larry Bird Drive. She often wondered, if the neighbor loved the game so much why he didn’t think of Larry Bird COURT…
I grew up in Kaukauna, WI, which used *produce Kaukauna Klub cheese. I don’t know the whole (possibly apocryphal) story, but somebody commented on the “Hawaiian cheese”. To be fair, it does sound Hawaiian.

* The production facilities moved to nearby Little Chute. The company was bought by the Bel group. At the original location there is a small park with a large crock shaped monument. I personally call it the “tomb of the unknown cheese”
We live in a street with an ‘interesting’ name.
It’s in the form of many, many very common street names like ‘Riverbank’ or ‘‘Mountainview’ - except that it has a bonus ‘s’ in the middle - so it’s like ‘Riversbank’ or ‘Mountainsview’ - it’s just wrong. It took us some time to get used to it when we moved in, and now, whenever we have to give our address to friends or tradespeople or delivery companies etc, we always automatically spell it out - it just saves time when they repeat it back to us, saying ‘Riverbank’, and we have to say - ‘No - Riversbank’ etc.
You do not see that very often. Most street names repeat all over the place, so having one that is truly unique in the whole country is pretty cool. It makes it easier to give directions and it stands out right away.
