PythagorAs - he wasn't Roman, you know.

Intersection is not PC anymore. It's interchange now. When was the last person executed for uttering "crossroad" in public?

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?
