Britain does have its shares of expressways, although not many. A fine example is the A38(M) Aston Expressway in northern Birmingham. It runs from the M6 at Spaghetti Junction towards the city centre. Even though it has motorway status, it is not grade separated. It goes for a few miles, and then turns into a Queensway, an urban Expressway right through the city centre of Birmingham, going through tunnels.

There are several dual carriageways (with physically separated carriageways) with at-grade intersections, though. Wouldn't you refer to those as "dual carriageways"?

Yes I would. In fact they are.

We agree, then

Defining concepts like "motorway", "freeway", "expressway", "highway" etc in a way that satisfies both native speakers and gives non-natives a common ground for discussion, isn't particularly easy. Different nations - even within Europe - sign these things differently, and definitions may differ. Italian "Superstrada" covers, the way I understand it, both divided and undivided roads, just like German "Kraftfahrstrasse" - or Norwegian "motortrafikkvei". In the UK, there is no such road category, as far as I know.

No not really. There are motorways, dual carriageways, expressways or Queensways and anything else are A or B roads.

Edit: country lanes. Wow!

Not really. Superstrada is a divided road which is not a motorway. Undivided road, although seldom referred to as "superstrada", are more commonly called "strada a scorrimento veloce".

Bear in mind that "superstrada" is not an official term, so its meaning may vary according to who's using it.

The term "Gelbe Autobahn" is also not an official one. The official term is an "Autobahnähnliche Straße" (motorway-like road). Although this term is generally not applied for two-lane roads in Germany. The term autoweg in Dutch is an official status, but is used for both 2-lane roads and 4-lane divided roads.

The meaning of the blue car sign varies by country. In most cases these are used for 4-lane expressways only, but in other countries, such as the Netherlands, Switzerland and Germany, it is used for two-lane roads as well, which may or may not have grade-separated interchanges.

This makes the term expressway somewhat vague, because its construction form varies by country and also within countries. A 4-lane divided and controlled-access highway that does not have motorway status is generally understood to be an expressway. Google Maps gives them the same colors as a full motorway.

In the Netherlands the blue car sign has the official name of "autoweg". In Austria and Germany a "bundestrasse" could mean anything, but they are always B-roads.

Are you sure? In the United States, an expressway is defined by the federal government’s Manual on Uniform Traffic Control Devices as a divided highway with partial control of access. But yes, in Europe we have our own definition of the word expressway (I guess that's in the Globish language).

Google maps is a mess in this sense, at least in Italy. Full motorways like A21 racc are rendered as expressways, and expressways like SS76 around Fabriano like normal roads. I wouldn't rely on Gmaps for a classification.

True, it used to be much better. Google Maps is destroying itself by poor quality control.

Circonvallazione = ring road.
Raccordo = spur
Tangenziale = connector or bypass (depending on context)

The technical name for divided controlled-access highways that are not autostrade is strada extraurbana principale. For 1+1 undivided controlled-access highways, the name is strada extraurbana secondaria.

The problem is that the blue highway symbol refers to strada extraurbana principale, whereas the blue car symbol only indicates that it is a road reserved for motor vehicles.

Tangenziale not ringroad or orbital?

Tangenziale is not necessarily a ring road: as its name may suggest, it's a road which is tangent to the city ring.

Mostly, yes. But terminology may vary. GRA is a ringroad but it is commonly known as Raccordo, because part of it was originally built to connect A1 and A2.

As Spinoza says, Tangenziale means only that goes tangent to the city. In Milan there are 3 tangenziali, but they are not orbital (unless you drive on all of them, but you have to pass 3 junctions).

In Rome there are 2 ring roads: GRA (Grande Raccordo Anulare is the name that has been made up from the surname of its creator, Engineer Gra, in facts it is not properly a Raccordo) which is a normal motorway (130 km/h, 3 lanes + emergency, completely grade-separated, green sings) and Tangenziale EST, deeper inside the city, but it is not completely grade-separated, limit is 40/50/70 km/h (depends on where you are) and the signs are white. It is almost completely round, but it is called Tangenziale.

Actually, tangenziale, raccordo, superstrada... all this terms are not legally recognized: so everyone uses as he prefers...

There is also another one... "Bretella".

Take a look at Lecce: the ring road there is formed by two tangenziali and one 'variante'

Bretella in english means suspender(s)... in the field of motorways it is mostly associated with A1 section Fiano Romano-San Cesareo, inaugurated in 1988 to connect directly A1 and (then) A2 without entering GRA.
