Why Are Some Roads Called Highways?
Hundreds of years ago, in England, certain main roads were built higher than the surrounding ground.
This was done to protect the road from flooding during rainy weather. Because they were higher, these roads were called highways.
Today, any main road or thoroughfare used by the public is called a highway. Highways have different names, depending on the type of highway it is.
Freeways, for example, are divided highways which carry a free flow of fast traffic. Other names for highways are expressways, thruways, and turnpikes.
