If I'm giving directions I will specify the road's actual signed name, but when I'm speaking of the topic in general, then any road that is part of the Federal Highway System and has an "I-##" name is an interstate, and every other kind of road that has two yellow lines down the middle of a good part of it (and a speed limit of 50 mph or higher) is a highway. (Normally a "highway" is 4 lanes nowadays, but sometimes I'll still encounter a 2-lane.)
My area does not have any toll roads, and the area where I grew up didn't have them, either. For that reason I refer to them as "toll roads" rather than tollways. I might use the term freeway, expressway, or thruway if I were travelling and needed to make myself understood, but those are all alien terms to me, they don't come naturally.
I do a fair amount of driving in greater Chicago, where the major highways have names as they pass through the city, and I've gotten into the habit of using the names because those are the designations that the traffic reporters use. So when Chicago is the topic, then you might hear me say "the Dan Ryan" or "the Eisenhower", but I don't do that anywhere else.
