It is characterized by its distinctive pattern of curved ramps that resemble the leaves of a four-leaf clover when viewed from above.

The word "cloverleaf" is used primarily in the context of transportation, civil engineering, and urban planning to describe a specific, common design for freeway interchanges. It functions as a countable noun.
Examples
