Life In Rome, Italy

There is a haphazard relationship, at best, between a thoroughfare's function and its name. For example, London's Abbey Road serves all the vital functions of a street, despite its name, and locals are more apt to refer to the "street" outside than the "road". A desolate road in rural Montana, on the other hand, may bear a sign proclaiming it "Davidson Street", but this does not make it a "street" except in the original sense of a paved road.
In the United Kingdom many towns will refer to their main thoroughfare as the High Street (in the United States it would be called the Main Street — however, occasionally "Main Street" in a city or town is a street other than the de facto main thoroughfare), and many of the ways leading off it will be named "Road" despite the urban setting. Thus the town's so-called "Roads" will actually be more street like than a road.
Some streets may even be seen as highways. Hurontario Street in Mississauga, Ontario, Canada, is commonly referred to as "Highway 10" — even though such a highway designation no longer officially exists. This is probably due to the fact that the street is a modern suburban arterial that was urbanized after decades of having the status and function a true highway, so people continued to use the number because of force of habit.
In some other English-speaking countries, such as New Zealand and Australia, cities are often divided by a main "Road," with "Streets" leading from this "Road", or are divided by thoroughfares known as "Streets" or "Roads" with no apparent differentiation between the two. In Auckland, for example, the main shopping precinct is around Queen Street and Karangahape Road.
