A cloverleaf interchange is a type of road junction that allows for smooth traffic flow between two highways. It features four loop ramps that connect the highways, enabling vehicles to change directions without stopping. This design minimizes the need for traffic signals and reduces congestion. The name "cloverleaf" comes from the shape of the interchange, which resembles a cloverleaf plant. These interchanges are commonly found in urban areas and are designed to accommodate high volumes of traffic, making them efficient for drivers traveling on interstate highways or major roads.
