What Does the Term Highway Interchange Mean?
An interchange is a point at which two or more highways cross. The term is most commonly used to refer to a road junction where one highway crosses another highway or a freeway interchange where one freeway crosses another.
A highway interchange typically includes ramps and other features to allow traffic to move between the highways without having to stop.
The number and design of the ramps will vary depending on the amount of traffic that is expected to use the interchange.
The first highway interchanges were built in the 1930s and they have become increasingly common as the number of vehicles on the road has increased. Highway interchanges can be found all over the world, and they are particularly common in the United States.
The term interchange can also be used to refer to a railway junction where two or more railways cross. However, this usage is less common than the usage of interchange to refer to a road junction.
