For me, it still depends on the size and importance of the road in question.
The house I grew up was in a long, wide, completely residential road - let's call it Westdown Avenue. I said then, and I still say, that that house was/is in Westdown Avenue. The flat I live in now is on a long, wide, major road that runs for over 3 miles from the centre of town to a fairly rural area nearby. Let's call it Lewis Road. I now say that my flat is on Lewis Road.
