The City of Tulsa is set to undergo a significant transformation in traffic management with the introduction of a diverging diamond interchange (DDI) at the intersection of Memorial Drive and the Creek Turnpike. This approximately $13 million project, funded through a combination of federal and state resources, aims to enhance safety and efficiency for the 47,000 vehicles that navigate this busy intersection daily.
The DDI, a relatively new traffic design, will allow vehicles to temporarily cross to the opposite side of the road while navigating the interchange. This innovative approach is expected to reduce the number of vehicle and pedestrian interactions, thereby decreasing the annual accident rate, which currently stands at about 134 incidents. Nationally, DDIs have been shown to reduce collisions by approximately one-third, making them a promising solution for Tulsa's traffic woes.
As construction progresses, city officials emphasize the importance of public education regarding the new traffic patterns. Drivers will need to adapt to navigating on the left side of the roadway while passing through the interchange before returning to the right side. New overhead signage will guide motorists, ensuring they are aware of lane requirements for turning onto the highways or continuing straight.
The DDI is not only expected to improve safety but also to enhance traffic flow, allowing for quicker movement through the intersection. With the successful implementation of this project, Tulsa will join Elk City as one of the few locations in Oklahoma to feature a diverging diamond interchange, with another planned for Gold Bay.
City officials urge residents to exercise patience as they adjust to this new traffic system, assuring them that the long-term benefits will lead to a safer and more efficient travel experience.
