And as long as I'm venting a bit here, what is it with Europeans and compass points? Their road signs tend to be gloriously well designed and easy to decipher, but they never include the words north, south, east, or west. So when you get to a crossroad, all the sign tells you is that one direction takes you to, say, Chard, and the other direction takes you to Axminster. Unless you've memorized the map, or happen to be a local who doesn't really need the sign in the first place, you don't know which direction to go. (If you're lucky, one of the cities on the sign is the one you want to go to, which makes things easy. Usually it's not.) But although I might not know every town and village in the area, I always know from a quick look at a map which general direction I want to go. So why not add the words north and south here? Some sort of EU-wide directive to banish directional notation, or what?JHM writes to ask:
Does the linked article ring true to you? If it is true that road signs tend not to indicate compass direction, I find this very odd indeed (even though (in New England at least) six or seven times out of ten the posted compass direction has a very low correlation to an actual compass point).JHM often writes to ask if things that he's read about Britain ring true for me, and I think I always say "yes, it's ringing". I suppose that illustrates the extent to which we get so accustomed to things being one way that we never imagine them being another way. In this case, I have to say "yes, it rings true, but..."
When I lived in South Africa (and had a car), I don't remember ever seeing a sign on a (BrE) motorway/(AmE) highway* with a direction on it. This got me lost in the (AmE) boondocks when I needed to get from a rural hotel in the Northern Province to Swaziland. None of the signs said which way was north or east, and none indicated how to get to the major towns in the province (or to the border). Instead, at each (chiefly AmE) intersection there were signs pointing toward(s) the next town on the road. One thus needed to know every single town along one's route in order to make sense of the signs. I imagine GPS is very useful there these days.
While I don't drive in the UK, on occasions I'm a passenger for a longish car journey (Americans would usually say trip, but that tends to be reserved for shorter journeys in BrE). Initially, I was only travel(l)ing for southeastern Scrabble league matches, and thus only

In Britain, people don't talk about "the A27 West" (though Google the phrase, and you'll think me a liar; but really, no one says it! At least not with the same name-like intonation that one says "Route 31 West"). When you join the A27, the sign will tell you about upcoming towns, not whether you're going east or west. If you're on that road driving east from Portsmouth, you have to get past Chichester before you start seeing signs for Brighton, if I remember correctly. So, if you want to get from Portsmouth to Brighton, you'd better know that Chichester is on the way. You need to constantly make decisions about which town to head toward on roads like the A27, since for the most part, they are not limited-access roads with on-ramps and off-ramps. They have roundabouts (often called traffic circles in the US, but rarely seen there--though I believe New Hampshire has quite a few). Lots of them. The signs on the roundabout exits will indicate the number of the routes and some number of upcoming towns/landmarks, as in the picture below.
So far, so much like my South African experience. But then I graduated from southeastern Scrabble events to national ones, and got to be a passenger on the M-roads, the national

Incidentally, in England people talk about the East (meaning the east of England, not 'the Orient') a lot less than the other directions. There are two reasons for this, I think. (1) There's a lot more West than East here--in that the island juts out, particularly in the Southwest. (2) London is treated (rightly or wrongly, depending on where you live) as the hub of the universe (sorry, Boston), and it's fairly eastward. So, striking out from London, there's very little to the East. Well, there's Essex (Americans: that's where Jamie Oliver is from. English folk: make it a new joke if you're going to make it). So, while you hear/see the North, the South and the West, and the Northeast/west and Southeast/west, you rarely hear about the East.
Back to the American side... as JHM notes, the directions on particular routes may bear little

Rather than designating the different types of route by letter, American route types are distinguished by the shapes of the shields on their signs (images/links courtesy of Wikipedia):
Interstate Highways | |
U.S. Routes | |
State Routes |
Side notes:
* Highway is probably the most dialect-neutral term in the US, and can apply to various types of routes--the key is that there's no stopping and starting on a highway. On the west coast, one tends to hear freeway. For limited-access roads in/around cities, I'd say expressway. Major toll roads, run by individual states, have their own names. In New York, it's the Thruway. Several other states have turnpikes, which is sometimes shortened to pike, as in the Mass Pike--that is, the Massachusetts Turnpike.
** Two things to know about AmE regionalisms when it comes to routes:
- Some Americans say route like root, others say it like rout. I grew up with the former, but the latter sometimes creeps into my speech because of other places I've lived. These dialect survey maps indicate that the 'rout' pronunciation is more common in the South and Midwest. In a forum on Canadian English, someone named Kirk says:
About "route," I use both pronunciations of the word depending on context. For instance, I've never heard anyone say "rowt 66"...it's always "root 66" for "route 66." So, if I see an official route as in a state route I definitely pronounce it "root." When I was younger I had a paper route and I almost always pronounced it "rowt" in that context. In other, general usages of the word, I use "root" and "rowt" pretty interchangeably.
My pattern and Kirk's pattern are the same. I grew up saying 'paper root', but now tend to say 'paper rout'.
- Southern Californians (and perhaps others) prefix route numbers with the, but Northeasterners like me don't. So, I'd say Take (Route) 5 but an Angeleno would say Take the 5.
