The Oklahoma Department of Transportation (ODOT) has announced plans to build a new 'diverging diamond' interchange near the Tulsa Hills shopping center. The construction project at the intersection of U.S. 75 and West 81st Street is scheduled to start in June 2026 and is expected to be completed nearly two years later.

Why it matters

Diverging diamond interchanges are becoming more common across the U.S. as they can improve traffic flow and safety at busy highway intersections. This new interchange is aimed at easing congestion and enhancing access to the popular Tulsa Hills shopping destination.

The details

The diverging diamond design will require drivers to briefly drive on the left side of the road as they pass through the interchange, allowing for more efficient left turns onto the highway. ODOT says the project will take nearly two years to complete due to the complexity of the construction.

  • Construction on the new interchange is set to begin in June 2026.
  • The project is expected to be finished nearly two years after the start of construction.
