1.highway
指城市街道的還有highway，不過這個指的是市區外的可以通行各種機動車輛的交通幹線，也可以指我們常說的高速公路。
例如：
The small village hugs the highway.
It would be connected by highway and rail to the capital and by rail only to Russia.
2.motorway
這個也是指高速公路，會更正式，特指的是為車輛快速通行而修建的專線，美語的話為freeway或者expressway。
例如：
Several cars piled up after ignoring the fog warning on the motorway.
What if he got out on the gridlocked freeway and went down the emergency exit; would the course of his life change?
I drove down another back road which will run next to the expressway and saw a frontloader knocking down a house.
