Partial cloverleaf interchange
（重定向自Partial cloverleaf）
A partial cloverleaf interchange or parclo is a modification of a cloverleaf interchange. The parclo interchange was developed by the Ontario Ministry of Transportation as a replacement for the cloverleaf on 400-Series Highways where full grade separation is not required, removing the dangerous weaving patterns and allowing for more acceleration and deceleration space on the freeway.
