Yeah, that's pretty much it. A parclo requires traffic lights on one road as it's a freeway-arterial interchange. But since the speed limit on Pembina is 50 or 60 in that area, it doesn't really need to be free flowing.

A parclo (only one in the city is Pembina and Bishop) takes all the exiting traffic off the highway, then provides separate merge lanes for entering traffic. Whereas with a cloverleaf, cars are accelerating up to 100 to merge as well as slowing down for the loop exit ramp, all in the same small strech of lane.

It's relatively cheap to convert a cloverleaf to a parclo, as all you have to do is close 2 loop ramps and realign/expand right turn ramps into exit ramps. The government could probably even make some money off it by selling the newly-freed up land just south of De Vos Road.
