What is an interchange in reference to a freeway?

An interchange refers to the connection of a freeway to another road or freeway through a series of ramps designed to allow vehicles to change routes without interfering with the flow of traffic. This design enhances safety and efficiency, as it enables smooth transitions for vehicles moving from one roadway to another without the need to stop at traffic signals or intersections.

Interchanges are critical features of freeway systems, as they facilitate the flow of traffic and help to minimize congestion. They can take various forms, such as cloverleafs, diamond interchanges, and others, depending on the geographical layout and traffic requirements. Understanding interchanges is essential for safe navigation on freeways and for comprehending how to effectively merge, exit, or transition to other routes. Other choices do not accurately describe the function or structure of an interchange.
