Best I could come up with for a UK contribution is the oddly hyphenated (oddly-hyphenated?) “St. Martin-in-the Fields Church Path”. I double checked on Google Street View and that is indeed how it’s spelled.
It’s a pedestrianised thoroughfare though, so I don’t know if it counts as a road as per the OP’s title.
No…we didn’t cut down those oak trees…they ran away in the middle of the night…I think that loud chainsaw noise you heard must have scared them…they’re probably in a forest right now having a good time with their other tree friends…I tell you what, we’ll even name the street after them.
According to this site (https://atkinsbookshelf.blog/tag/longest-street-name-in-us/ ) the longest street name in US is Northeast Kentucky Industrial Parkway in Northeast Kentucky, but they don’t say how they found or verified that, so it might be incorrect.
Clos des Compagnons Batisseurs, a street in Evere near the Belgian capital
and the slightly longer
Burgemeester Baron van Voerst van Lyndenstraat in Gramsbergen, Overijsssel (sic, all three s’s)
Again, it’s not obvious to me that these are correct. But the are long.

I could swear I once saw a city where the similar street was the full title “Reverend Doctor Martin Luther King Jr.” which would be hard to fit on a sign.
The longest street name I ever saw was when I lived in NC; I frequently drove along NC-54 west of Chapel Hill, and was always amused by “Bethel Hickory Grove Church Road”.
Houston has Staff Sergeant Macario Garcia Drive, abbreviated(it would have to be) on street signs as: S/Sgt Macario Garcia Dr. Google misinterprets the “S” for Staff as South.
Named after the famous London Church of St Martin-in-the-Fields (which used to be in the country some distance outside the city walls before London grew around it).
In Portsmouth, UK, there’s a street that was renamed “The Ocean at the End of the Lane” in honour of Neil Gaiman’s book of the same title (Neil Gaiman spent part of his early life in the area).
The council actually had trouble naming the street in their systems, because the ‘lane/road/street/avenue/etc’ suffix of the road names is usually stored in a separate database field, so this road would have been called ‘The Ocean at the End of the’, ‘Lane’. There was much debate about breaking database conventions, but I think in the end, they accepted it has no suffix, and ‘Lane’ is part of the name.
