That's why we have the good ol' cloverleaf interchange. Works wonders at the crossing of two highways, and you can always get from any direction to any other quickly and easily. Oddly enough, to go back where you came from you make two lefts - not two rights.

The cloverleaf would get my vote for "best", because where you need one it's well worth all the space it takes up.
