663:, about 15 miles (24 km) south of the I-64 crossing. This particular interchange is a conversion from a four-loop design at the location of one of the toll booths on the Bluegrass Parkway before its conversion into a freeway. Toll booths were located directly below US 127; through traffic used the through lanes, while both entering and exiting traffic shared a lane directly to the right of the through lanes. The old design was standard for interchanges at toll booths in Kentucky's parkway system of controlled-access toll roads; even though tolls have been removed from all of the roads, many of the old designs still exist at former toll booth sites.
424:, where the ramps can be added without widening the street overpass/underpass to include deceleration lanes (normally needed on the A4 in order to safely enter the loop ramps that lead to the freeway). The parclo A2 and B2 ramps are also usually longer and allow for higher speeds than their A4 counterparts because of rural land availability. It is possible to upgrade an A2 to an A4 by adding directional ramps, serving arterial-to-freeway traffic that would otherwise be forced to make a left turn to enter the loop ramps.

A single large barrier can serve each onramp/offramp pair simultaneously, reducing construction and operation expenses at through junctions. When possible, such as at terminal junctions,

is one of the most popular designs, as all movements from the arterial road to the entrance ramps are made by right-hand turns, providing for a safer entrance to the freeway by eliminating left-hand turns into opposing traffic (which require queues waiting to make such turns). This also makes logical

The parclo A4 (also called "six-ramp partial cloverleaf") contains six ramps. On each side on the freeway, there is an (often multi-lane) exit ramp, followed by a loop ramp and directional ramp entering the freeway. The on-ramps are in the same configuration as a cloverleaf interchange, but there is
452:
Some parclos have the right-turning (directional) on-ramp leave the arterial road after the exit ramp intersection. This configuration is often used when another road meets the freeway off-ramp and gives traffic from this road the option of turning right to use the directional on-ramp to enter the

Traffic exiting the freeway to the arterial road is provided with a long, relatively straight exit ramp, preventing most speed-related rollovers. These exit ramps are also frequently multi-laned to accommodate traffic turning left, right, or going straight ahead in some cases. Traffic signals are

Parclo A2 and B2 configurations contain four ramps. On each side of the freeway there is a loop ramp and a directional ramp. In parclo A2, the loop ramps serve as on-ramps and the directional ramps serve as off-ramps. In parclo B2 the roles are reversed. Both on- and off-ramps require controlled

The parclo B4 interchange superficially appears to be a mirror image of the parclo A4. However, the B4 design provides freeway-to-arterial ramps without traffic lights, while traffic turning left from the arterial must cross opposing traffic. Although this design has the potential to flood the

arterial with more freeway traffic than the parclo A4, one particular advantage is the ability to coordinate the traffic signals on the arterial in both directions independently. This is useful when there is more through-movement traffic on the arterial than turning traffic.

The number designates how many quadrants of the interchange contain ramps. In left-hand drive countries, the ramps function the same as in right-hand drive countries, but ramps with the same designation appear visually reversed. Common parclo configurations include the

The junction of
Saskatchewan Highway 1 (east-west), Saskatchewan Highway 39 (south, part of the CanAm route) and Saskatchewan Highway 301 (north) is an A4 parclo. Highway 1 serves as the freeway, while Highway 39/301 is the arterial road.
