A cloverleaf interchange provides unrestricted movements between a freeway and another high-capacity roadway (including another freeway or an expressway). There are eight ramps total in this configuration. In addition to an outside diamond configuration, the cloverleaf interchange also features internal loop ramps so that traffic signals and stop signs are not required. The cloverleaf interchange is so named because the internal connecting ramps look like a four-leaf clover from above. Due to the weaving that is required to get between the loop ramps and main lanes, many cloverleaf interchanges have been replaced with single point urban interchanges (SPUI), diverging diamond interchanges (DDI) or parclo interchanges where two of the loop ramps are simply removed. See Kurumi’s Cloverleaf Interchanges for more.
