Greenwood breaks ground on “Diverging Diamond” Interchange

GREENWOOD, Ind. (WISH) – Greenwood officials broke ground on its new $16 million interchange off I-65. But it’s not any regular highway exit. It’s called a Diverging Diamond Interchange.

Driver will sort of make a figure eight as they go through it.

It’s a new concept in Central Indiana and Greenwood officials are hoping it brings new business south of Indianapolis.

“As I-65 continues to grow and the I-65 corridor grows we’ve seen a big noon on the south side of the city. But we need this interstate exchange to open up,” said Mayor Mark Meyers

The exit will be between exits 99 and 95. But at the end you won’t make your regular left or right. As you exit the highway or pass over Worthsville Road you will stay to the left. Once you pass over you will then be directed back to the right.

“It’s a safer intersection, moves traffic better than traditional concepts and it will help free up traffic along this corridor into the future,” said Adam Burns of Crawford, Murphy & Tully which designs traffic patters for INDOT.

But in order for the interchange to be built, something had to go. The state made land purchases and used eminent domain to make the project happen

Much of the land around the exit is empty farmland. But some property was seized by the state. Negotiations with land owners stalled the project for years

“You’re not going to make everybody happy all the time but we are trying as hard as we can. We’re being as reasonable as we can,” said Mayor Meyers.

The Diverging Diamond design as only been used in Indiana in the Fort Wayne area.

But by using it, officials say it saved $6 million and shortened the project’s time frame. It’s scheduled to open by next Thanksgiving. provides commenting to allow for constructive discussion on the stories we cover.
