These are used extensively here in Utah. Most new interchanges are done this way and many older ones are being rebuilt to the new configuration. They can get quite complex when dealing with frontage roads, but they still work better than the original.

Cloverleafs use a lot of space.

They also like the Displaced Left-Turn Intersection here for busy surface streets.
