Interchange (road) - Wikipedia
In the field of road transport, an interchange (American English) or a grade-separated junction (British English) is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through ...
Interchanges facilitates the change of direction of traffic from one highway to another highway at intersections. A type of road junction linking one controlled-access highway (freeway or motorway) facility to another, to other roads, or to a rest area or motorway service area.
Main Design of Highway Interchanges
There is a wide variety of interchange designs, with the most common including: Trumpet interchange.

Also called T interchange and allows one highway to end/begin perpendicularly to another highway.
