Interchanges

Cloverleaf

Four symmetrical loops — it's impossible to miss a cloverleaf. If you can find one, that is.

A junction with no bridges and not much choice if you're on the side road.

Fork

It might be the simplest type of interchange there is. One way on and one way off: a fork in the road.
