Diverging diamond interchange proposed for Greenwood

A new Interstate 65 interchange could take some getting used to for Johnson County drivers.

One of the designs the Indiana Department of Transportation is considering for a new I-65 interchange in Greenwood is so novel that you won’t find it anywhere else in the state.

Drivers would briefly cross over to the wrong side of the road, something they normally wouldn’t do unless passing a slowpoke. But that configuration lets motorists merge onto the highway ramps without having to turn left in front of oncoming traffic.

France came up with the idea for the diverging diamond interchange, where vehicles crisscross into the opposite lanes before getting onto the highway ramps or just continuing straight. Missouri brought the highway exit design to the United States three years ago.
