I have a doubt about which is which between "highway", "freeway" and "expressway"... (and the dictionary didn't help me!) I feel the translation will be a problem, since most probably we don't call them the same in Argentina/ Cuba/ Spain/ etc., so I guess an English-speaker could explain the difference among them to me? (which one is free, which one has toll, with/without exits, etc?).
thanks a lot!
