An interchange in Tulsa, Oklahoma, earned the name "Tulsa Stonehenge," or "Traffic Henge," due to rows of empty bridge piers. Now construction has begun on those empty piers to complete a long-delayed construction plan.

The Oklahoma Department of Transportation (ODOT) began on Monday, April 8 for an interchange improvement project at I-44 and US-75. The abandoned bridge piers were part of the first phase of the project, which was completed in 2023.
