A cloverleaf is a type of interchange used in road systems, designed to allow vehicles to change directions without stopping. It features a series of looping ramps that connect different roads, enabling smooth transitions between highways and local streets. This design helps reduce traffic congestion and improves safety by minimizing the need for traffic signals. Cloverleaf interchanges are commonly found in urban areas where multiple highways intersect. They are named for their shape, which resembles a four-leaf clover when viewed from above. This efficient layout is often used in conjunction with other road designs, such as overpasses and underpasses, to facilitate the flow of traffic.
