Sure, thanks. Fall on my sword for that! I knew it wasn't right. And I knew the spelling really. You know those days when a word, even if spelt right, just doesn't look right?

What's un-pc about "Intersection"?

When was ANYONE executed for it! ???? Or intersection?

To us an interchange is where 2 or more motorways (freeways/interstates/turnpikes) merge or diverge, with all the ensuing spaghetti.

>Speaking of PC road talk, I noticed yesterday that "bridge freezes before freeway". Which got me quite confused - what about the locked-up-way, highway, parkway, driveway, road, route, turnpike (my apologies if I left any out)? In which particular order do they freeze, if ever, and is it before or after the bridge?

Must admit that sprang to my mind when I read it too.

Here, when exiting a motorway, say, for the service area, they have a sign "End of Motorway Regulations". I used to debate with myself as to whether it was "end of regulatuions that apply when on a motorway" or "special regulations you have to obey at the end of the motorway" :-)
