Tulsa launches diverging diamond interchange to improve traffic flow and safety

The City of Tulsa is set to enhance traffic safety and efficiency with the upcoming construction of a diverging diamond interchange (DDI) at the intersection of Memorial Drive and the Creek Turnpike. This innovative traffic solution aims to reduce congestion and accidents, which have been a significant concern in the area.

Currently, the intersection experiences approximately 47,000 vehicles daily and reports around 34 accidents each year. The DDI design allows vehicles to temporarily switch to the opposite side of the road, facilitating smoother traffic flow and minimizing points of conflict between cars and pedestrians. This method has proven effective in other communities, reducing collisions by about one-third and increasing overall traffic efficiency.

As Tulsa prepares for this new interchange, officials emphasize the importance of public awareness and patience. Drivers will notice new overhead signage guiding them through the DDI, which will help navigate the changes. While the DDI is a relatively new concept in Oklahoma, with only one existing example in Elk City, it promises to significantly improve safety and traffic conditions in Tulsa.

City leaders encourage residents to stay informed about the project and its benefits. For more details on the diverging diamond and other ongoing transportation projects, residents can visit the South Tulsa Roads page on the Tulsa Council website. The city appreciates the community's patience during this transition, assuring that the long-term benefits will be worth the initial adjustment period.
