A partial cloverleaf interchange or parclo is a modification of a cloverleaf interchange.

The design, originally invented by the Ontario Ministry of Transportation has been well received, and has since become one of the most popular freeway-to-arterial interchange designs in North America, because it is a modified cloverleaf interchange that maximizes traffic flow and but eliminates weaving. It has also been used occasionally in some European countries, such as Germany, Hungary, Italy, the Netherlands, and the United Kingdom.
