You will note the "no lights" is being acomplished with a flyover; which as I said before requires a lot of space.

That looks somewhat similar to the Crowchild / Glenmore flyover. Appears to be a good (but expensive?) solution when one leg of the cloverleaf is expected to handle a lot of traffic. Could get icy quick in the wintertime though.
