I fed you this message, knowing you'd dine out on it! :-)

Yes, we have cross roads just the same, but a general intersection is a junction.

To us an interchange is where two or more motorways meets - all that spaghetti.

>Ah but then someone may get confused and think "finally one that works" and just step on it. But they also can't say "road being built" because it's too long, or "road building" because it's too ambiguous (would that be a "roadhouse", or "what is this road building now" or - this is one of those where you have ambiguity with not enough context to disambiguate); and it also can't be "road under building" because everyone would say "under which building? I don't see any" - so it's the shortest unambiguous phrase possible: "road under construction".

Quite finished ? .....

Ha Ha. We don't have that sign - just the "no entry" disc at the "wrong way" end.

Sorry - meant "median" - comes from living within spitting distance of the Greenwich Meridian here :-)

Actually, I think you'll find that the rear luggage compartment on the old horse buggies is still called the boot. To us a trunk is the large box you drag onto passenger liners.
