A Michigan left is an at-grade intersection design which replaces each left turn with a permutation of a U-turn and a right turn. The design was given the name due to its frequent use along Michigan roads and highways since the late 1960s. In other contexts, the intersection is called a median U-turn crossover or median U-turn. The design is also sometimes referred to as a boulevard turnaround or a thru turn intersection.
