Which of the following is a possible example of a "system interchange"?

A system interchange is a type of interchange that connects two or more major highways or freeways, allowing for the smooth transition of traffic between them. The primary purpose of these interchanges is to facilitate high-capacity travel without the disruption that might arise from intersections.

In the case of a cloverleaf interchange, it is designed specifically to handle large volumes of traffic flowing between two intersecting roadways, typically freeways. This type of interchange uses loop ramps to allow vehicles to enter and exit without direct stop-and-go situations, effectively managing the flow and improving traffic conditions. With its configuration of circular loops and bridges, a cloverleaf interchange exemplifies a system interchange that enhances connectivity and operational efficiency between major routes.

Other options like a diamond interchange or a partial cloverleaf may be suitable for connecting roads but are typically meant for situations with lower traffic volumes or at grade intersections rather than the high-capacity demands seen in system interchanges. The single point urban interchange (SPUI), while efficient in urban settings, serves specific configurations and does not represent the broader, largely highway-focused nature of system interchanges like the cloverleaf does.
