The diverging diamond interchange

American interchanges can take many forms – see this field guide to highway interchanges from The Infrastructurist – including one called “the diverging diamond.” The goal is to provide better traffic flow from a road onto a highway through switching the lanes of traffic through the interchange area. That is, traffic entering on the right side of the road are then driving on the left through the interchange and vice versa.

Illinois Department of Transportation officials are considering this design, primarily being touted by Missouri officials, for an interchange in Naperville. See the design here and the background to the interchange here.
